TWiki Access Control

Restricting read and write access to topics and webs, by Users and groups

TWikiAccessControl allows you restrict access to single topics and entire webs, by individual user and by user Groups, in three areas: view; edit & attach; and rename/move/delete. Access control, combined with TWikiUserAuthentication?, lets you easily create and manage an extremely flexible, fine-grained privilege system.

An Important Control Consideration

Open, freeform editing is the essence of WikiCulture - what makes TWiki different and often more effective than other collaboration tools. For that reason, it is strongly recommended that decisions to restrict read or write access to a web or a topic are made with care - the more restrictions, the less Wiki in the mix. Experience shows that unrestricted write access works very well because:

  • Peer influence is enough to ensure that only relevant content is posted.

  • Peer editing - the ability for anyone to rearrange all content on a page - keeps topics focussed.

  • In TWiki, content is transparently preserved under revision control:
    • Edits can be undone by the TWikiAdminGroup (the default administrators group; see #ManagingGroups).
    • Users are encouraged to edit and refactor (condense a long topic), since there's a safety net.

As a collaboration guideline:

  • Create broad-based Groups (for more and varied input), and...
  • Avoid creating view-only Users (if you can read it, you should be able to contribute to it).

Authentication vs. Access Control

Authentication: Identifies who a user is based on a login procedure. See TWikiUserAuthentication?.

Access control: Restrict access to content based on users and groups once a user is identified.

Users and Groups

Access control is based on the familiar concept of Users and Groups. Users are defined by their WikiNames. They can then be organized in unlimited combinations by inclusion in one or more user Groups. For convenience, Groups can also be included in other Groups.

Managing Users

A user can create an account in TWikiRegistration?. The following actions are performed:

  • WikiName and encrypted password are recorded in .htpasswd if authentication is enabled.
  • A confirmation e-mail is sent to the user.
  • A user home page with the WikiName of the user is created in the Main web.
  • The user is added to the TWikiUsers topic.

Users can be authenticated using Basic Authentication (htaccess) or SSL (secure server). In either case, TWikiUserAuthentication? is required in order to track user identities, and use User and Group access control.

The default visitor name is TWikiGuest. This is the non-authenticated user.

Managing Groups

Groups are defined by group topics created in the Main web, like the TWikiAdminGroup. To create a new group:

  1. Edit TWikiGroups by entering a new topic with a name that ends in Group. Example:
    • SomeGroup
  2. Set Preferences for two Variables in the new group topic:
    • Set GROUP = < list of Users and/or Groups >
    • Set ALLOWTOPICCHANGE = < list of Users and/or Groups >
    • The GROUP variable is a comma-separated list of Users and/or other Groups. Example:
      • Set GROUP = Main.SomeUser, Main.OtherUser, Main.SomeGroup
    • ALLOWTOPICCHANGE defines who is allowed to change the group topic; it is a comma delimited list of Users and Groups. You typically want to restrict that to the members of the group itself, so it should contain the name of the topic. (This prevents Users not in the Group from editing the topic to give themselves or others access. For example, for the TWikiAdminGroup topic write:
    • Set ALLOWTOPICCHANGE = Main.TWikiAdminGroup

Restricting Write Access

You can define who is allowed to make changes to a web or a topic.

Deny Editing by Topic

Denying editing of a topic also restricts file attachment; both privileges are assigned together.

  • Define one or both of these variables in a topic, preferably at the end of the page:
    • Set DENYTOPICCHANGE = < list of Users and Groups >
    • Set ALLOWTOPICCHANGE = < list of Users and Groups >

  • DENYTOPICCHANGE defines Users or Groups that are not allowed to make changes to the topic, with a comma-delimited list. Example:
    • Set DENYTOPICCHANGE = Main.SomeBadBoy, Main.SomeBadGirl, Main.SomeHackerGroup

  • ALLOWTOPICCHANGE defines Users or Groups that are allowed to make changes to the topic. It is a comma delimited list of Users and Groups. Example:
    • Set ALLOWTOPICCHANGE = Main.SomeGoodGuy, Main.SomeGoodGirl, Main.TWikiAdminGroup

  • DENYTOPICCHANGE is evaluated before ALLOWTOPICCHANGE. Access is denied if the authenticated person is in the DENYTOPICCHANGE list, or not in the ALLOWTOPICCHANGE list. Access is granted in case DENYTOPICCHANGE and ALLOWTOPICCHANGE is not defined.

Deny Editing by Web

Restricting web-level editing blocks creating new topics, changing topics or attaching files.

  • Define one or both of these variable in the WebPreferences topic:
    • Set DENYWEBCHANGE = < list of Users and Groups >
    • Set ALLOWWEBCHANGE = < list of Users and Groups >

The same rules apply as for restricting topics, with these additions:

  • DENYTOPICCHANGE (in topic) overrides DENYWEBCHANGE (in WebPreferences)
  • ALLOWTOPICCHANGE (in topic) overrides ALLOWWEBCHANGE (in WebPreferences)

Restricting Rename Access

You can define who is allowed to rename, move or delete a topic, or rename a web.

Deny Renaming by Topic

To allow a user to rename, move or delete a topic, they also need write (editing) permission. They also need write access to change references in referring topics.

  • Define one or both of these variables in a topic, preferably at the end of the topic:
    • Set DENYTOPICRENAME = < list of Users and Groups >
    • Set ALLOWTOPICRENAME = < list of Users and Groups >

  • DENYTOPICCRENAME defines Users or Groups that are not allowed to rename the topic. It is a comma delimited list of Users and Groups. Example:
    • Set DENYTOPICRENAME = Main.SomeBadBoy, Main.SomeBadGirl, Main.SomeHackerGroup

  • ALLOWTOPICRENAME defines Users or Groups that are allowed to rename the topic. It is a comma delimited list of Users and Groups. Example:
    • Set ALLOWTOPICRENAME = Main.SomeGoodGuy, Main.SomeGoodGirl, Main.TWikiAdminGroup

  • DENYTOPICRENAME is evaluated before ALLOWTOPICRENAME. Access is denied if the authenticated person is in the DENYTOPICRENAME list, or not in the ALLOWTOPICRENAME list. Access is granted in case DENYTOPICRENAME and ALLOWTOPICRENAME is not defined.

Deny Renaming by Web

You can define restrictions of who is allowed to rename a TWiki web.

  • Define one or both of these variable in the WebPreferences topic:
    • Set DENYWEBRENAME = < list of Users and Groups >
    • Set ALLOWWEBRENAME = < list of Users and Groups >

The same rules apply as for topics, with these additions:

  • DENYTOPICRENAME (in topic) overrides DENYWEBRENAME (in WebPreferences)
  • ALLOWTOPICRENAME (in topic) overrides ALLOWWEBRENAME (in WebPreferences)

Restricting Read Access

You can define who is allowed to see a web.

Deny Viewing by Topic

ALERT! Technically it is possible to restrict read access to an individual topic based on DENYTOPICVIEW / ALLOWTOPICVIEW preferences variables, provided that the view script is authenticated. However this setup is not recommended since all content is searchable within a web - a search will turn up view restricted topics.

Deny Viewing by Web

You can define restrictions of who is allowed to view a TWiki web. You can restrict access to certain webs to selected Users and Groups, by:

  • obfuscating webs: Insecure but handy method to hide new webs until content is ready for deployment.
  • authenticating all webs and restricting selected webs: Topic access in all webs is authenticated, and selected webs have restricted access.
  • authenticating and restricting selected webs only: Provide unrestricted viewing access to open webs, with authentication and restriction only on selected webs.

Obfuscate Webs

The idea is to keep a web hidden by not publishing its URL and by preventing the all webs search option from accessing obfuscated webs. Do so by enabling the NOSEARCHALL variable in WebPreferences:

  • Set NOSEARCHALL = on

This setup can be useful to hide a new web until content its ready for deployment.

ALERT! Obfuscating webs is insecure, as anyone who knows the URL can access the web.

Authenticate all Webs and Restrict Selected Webs

Use the following setup to authenticate users for topic viewing in all webs and to restrict access to selected webs:

  1. Restrict view access to selected Users and Groups. Set one or both of these variables in its WebPreferences topic:
    • Set DENYWEBVIEW = < list of Users and Groups >
    • Set ALLOWWEBVIEW = < list of Users and Groups >
    • Note: DENYWEBVIEW is evaluated before ALLOWWEBVIEW. Access is denied if the authenticated person is in the DENYWEBVIEW list, or not in the ALLOWWEBVIEW list. Access is granted in case DENYWEBVIEW and ALLOWWEBVIEW is not defined.
  2. Hide the web from an "all webs" search. Enable this restriction with the NOSEARCHALL variable in its WebPreferences topic:
    • Set NOSEARCHALL = on
  3. Add view to the list of authenticated scripts in the .htaccess file.

HELP This method only works if the view script is authenticated, which means that all Users have to login, even for read-only access. (An open guest account, like TWikiGuest, can get around this, allowing anyone to login to a common account with, for example, view-only access for public webs.) TWikiInstallationGuide? has more on Basic Authentication, using the .htaccess file.

Authenticate and Restricting Selected Webs Only

Use the following setup to provide unrestricted viewing access to open webs, with authentication only on selected webs:

  1. Restrict view access to selected Users and Groups. Set one or both of these variables in its WebPreferences topic:
    • Set DENYWEBVIEW = < list of Users and Groups >
    • Set ALLOWWEBVIEW = < list of Users and Groups >
    • Note: DENYWEBVIEW is evaluated before ALLOWWEBVIEW. Access is denied if the authenticated person is in the DENYWEBVIEW list, or not in the ALLOWWEBVIEW list. Access is granted in case DENYWEBVIEW and ALLOWWEBVIEW is not defined.
  2. Hide the web from an "all webs" search. Enable this restriction with the NOSEARCHALL variable in its WebPreferences topic:
    • Set NOSEARCHALL = on
  3. Enable the $doRememberRemoteUser flag in lib/TWiki.cfg as described in TWikiUserAuthentication?. TWiki will now remember the IP address of an authenticated user.
  4. Copy the view script to viewauth (or better, create a symbolic link)
  5. Add viewauth to the list of authenticated scripts in the .htaccess file. The view script should not be listed in the .htaccess file.

When a user accesses a web where you enabled view restriction, TWiki will redirect from the view script to the viewauth script once (this happens only if the user has never edited a topic). Doing so will ask for authentication. The viewauth script shows the requested topic if the user could log on and if the user is authorized to see that web.

ALERT! Authenticating webs is not very secure, as there is a way to circumvent the read access restriction. It can be useful in certain situations - for example, to simplify site organization and clutter, by hiding low traffic webs - but is not recommended for securing sensitive content.

Hiding Control Settings

TIP To hide access control settings from normal browser viewing, place them in comment markers.

<!--
   * Set DENYTOPICCHANGE = Main.SomeGroup
-->

The SuperAdminGroup

By mistyping a user or group name in the ALLOWTOPICCHANGE setting, it's possible to lock a topic so that no-one can edit it from a browser. To avoid this, you can create Web-based superusers:

  • Set the $superAdminGroup variable in lib/TWiki.cfg to the name of a group of Users who are always allowed to edit/view topics.
$superAdminGroup = "TWikiAdminGroup";
  • The default setting is not to have superusers.

TWiki Text Formatting

Working in TWiki is as easy as typing in text - exactly like email. You don't need to know HTML, though you can use it if you prefer. Links to topics are created automatically when you enter WikiWords. And TWiki shorthand gives you all the power of HTML with a simple coding system that takes no time to learn. It's all laid out below - refer back to this page in a pop-up window from the Edit screen.

TWiki Editing Shorthand

Formatting Command: Example: You write: You get:
Paragraphs:
Blank lines will create new paragraphs.
1st paragraph

2nd paragraph
1st paragraph

2nd paragraph

Headings:
At least three dashes at the beginning of a line, followed by plus signs and the heading text. One plus creates a level 1 heading (most important), two pluses a level 2 heading; the maximum is level 6. Note: A Table of Content can be created automatically with the %TOC% variable, see TWikiVariables. Any heading text after !! is excluded from the TOC; for example, write ---+!! text if you do not want to list a header in the TOC.
---++ Sushi

---+++ Maguro

Verbatim Mode:
Surround code excerpts and other formatted text with <verbatim> and </verbatim> tags.
Note: Use <pre> and </pre> tags instead if you want that HTML code is interpreted.
Note: Each tag must be on a line by itself.
<verbatim>

Table:
Any number of lines of text. Each line is one row of the table consisting of one or more cells. Each cell starts and ends with a vertical bar '|'. Any spaces at the beginning of a line are ignored.
Notes:
| *bold* | cells are displayed as table headers.
|   center-spaced   | cells are displayed center aligned.
|     right-spaced | cells are displayed right aligned.
| 2 colspan || cells are displayed as multi-span columns (i.e., a cell with no text spans a column).
|^| cells with a caret indicate follow-up rows of multi-span rows (this functionality is provided by TablePlugin?).
• If a row contains a large amount of text, and you want it to be more readable while editing the table, split the row into multiple text lines by ending each line with a backslash character '\'.
• Table cells wrap automatically as determined by the browser.

WikiWord Links:
CapitalizedWordsStuckTogether (or WikiWords) will produce a link automatically.
Note: In case you want to link to a topic in a different TWiki web write Otherweb.TopicName. (The link label is the the name of the web in case the is WebHome, else it is the topic name)
WebNotify

Main.TWikiUsers
WebNotify

TWikiUsers

Forced Links:
You can create a forced internal link by enclosing words in double square brackets.
Note: Text within the brackets may contain optional spaces; the topic name is formed by capitalizing the initial letter and by removing the spaces; for example, [[text formatting FAQ]] links to topic TextFormattingFAQ. You can also refer to a different web and use anchors.
Note: To "escape" double square brackets that would otherwise be a correct link, prefix the leading left square brackets with an exclamation point, that is, begin with ![[....
[[wiki syntax]]

[[Main.TWiki users]]

escaped:
![[wiki syntax]]
wiki syntax

Main.TWiki users

escaped: [[wiki syntax]]

Specific Links:
Create a link where you can specify the link text and the link reference separately, using nested square brackets like [[reference][text]]. Internal link references (e.g. WikiSyntax) and external link references (e.g. http://TWiki.org/) are supported.
Note: The same Forced Links rules apply for internal link references.
Note: For external link references, you can simply use a space instead of ][ to separate the link URL from the descriptive text.
Note: Anchor names can be added as well, like [[WebHome#MyAnchor][go home]] and [[http://gnu.org/#Action][GNU Action]].
[[WikiSyntax][syntax]]

[[http://gnu.org][GNU]]

[[http://xml.org XML]]
syntax

GNU

XML

Anchors:
You can define a link reference inside a TWiki topic (called an anchor name) and link to that. To define an anchor write #AnchorName at the beginning of a line. The anchor name must be a WikiWord. To link to an anchor name use the [[MyTopic#MyAnchor]] syntax. You can omit the topic name if you want to link within the same topic.
[[WikiWord#NotThere]]

[[#MyAnchor][Jump]]

#MyAnchor To here
WikiWord#NotThere

Jump

To here

Prevent a Link:
Prevent a WikiWord from being linked by prepending it with an exclamation point.
!SunOS
SunOS
Disable Links:
You can disable automatic linking of WikiWords by surrounding text with <noautolink> and </noautolink> tags.
Note: Each tag must be on a line by itself.
Note: This also works for TWiki tables, but only if you add a blank line between the end of the table and the closing </noautolink> tag (known issue of the TablePlugin?).
 <noautolink>
 RedHat &
 SuSE
 </noautolink>
RedHat & SuSE
Mailto: Links:
To create 'mailto:' links that have more descriptive link text, specify subject lines or message bodies, or omit the email address, you can write [[mailto:user@domain descriptive text]].
[[mailto:a@z.com Mail]]

[[mailto:?subject=Hi Hi]]
Mail

Hi

Using HTML

You can use just about any HTML tag without a problem - however, there are a few usability and technical considerations to keep in mind.

HTML and TWiki Usability

  • TIP TIP: On collaboration pages, it's preferable NOT to use HTML, and to use TWiki shorthand instead - this keeps the text uncluttered and easy to edit.
  • ALERT! NOTE: TWiki is designed to work with a wide range of browsers and computer platforms, holding to HTML 4.0 and XHTML 1.0 compatibility in the standard installation - adding raw HTML, particularly browser-specific tags (or any other mark-up that doesn't degrade well) will reduce compatibility.
  • Recommondations when using HTML:
    • Use XHTML 1.0 Transitional syntax
    • Do not span a tag over more then one line
    • Remove all empty lines. TWiki inserts <p /> paragraph tags on empty lines, which causes problems if done between tags that do not allow paragraph tags, like for example between table tags.

TWiki HTML Rendering

  • TWiki converts shorthand notation to XHTML 1.0 for display. To copy a fully marked-up page, simply view source in your browser and save the contents.
    • TIP If you need to save HTML frequently, you may want to check out TWiki:Plugins/GenHTMLAddon - it will "generate a directory containing rendered versions of a set of TWiki pages together with any attached files."
  • ALERT! NOTE: The opening and closing angle brackets - <...> - of an HTML tag must be on the same line, or the tag will be broken.
    • This feature allows you to enter an unclosed angle bracket - as a greater than or less than symbol - and have it automatically rendered as if you had entered its HTML character, &lt;, ex: a < b
    • TIP If you're pasting in preformatted HTML text and notice problems, check the file in a text processor with no text wrap. Also, save without hard line breaks on text wrap, in your HTML editing program.

TWiki and JavaScript

You can use JavaScript for your TWiki applications. Since TWiki rendering might interfere with JavaScript code you need to escape it with HTML comments and <pre> tags:

<script type="text/javascript">
<!-- Hide JavaScript and <pre> escape TWiki rendering
... put your JavaScript code here...
// Stop hiding and stop </pre> escaping TWiki rendering -->
</script>

Hyperlinks

Being able to create links without any formatting required is a core TWiki feature, made possible with WikiWords. New TWiki linking rules are a simple extension of the syntax that provide a new set of flexible options.

Internal Links

  • GoodStyle is a WikiWord that links to the GoodStyle topic located in the current TWiki web.

  • NotExistingYet? is a topic waiting to be written. Create the topic by clicking on the ?. (Try clicking, but then, Cancel - creating the topic would wreck this example!)

External Links

  • http://..., https://..., ftp://..., gopher://..., news://..., file://..., telnet://... and mailto:...@... are linked automatically.

  • Email addresses like name@domain.com are linked automatically.

  • [[Square bracket rules]] let you easily create non-WikiWord links.
    • You can also write [[http://yahoo.com Yahoo home page]] as an easier way of doing external links with descriptive text for the link, such as Yahoo home page.

TWiki Variables

Variables are names that are enclosed in percent signs % that are expanded on the fly.

  • %TOC% : Automatically generates a table of contents based on headings in a topic - see the top of this page for an example.

  • %WEB% : The current web, is Tutorial.

  • %TOPIC% : The current topic name, is TextFormattingRules.

  • %ATTACHURL% : The attachment URL of the current topic. Example usage: If you attach a file to a topic you can refer to it as %ATTACHURL%/image.gif to show the URL of the file or the image in your text.

  • %INCLUDE{"SomeTopic"}% : Server side include, includes another topic. The current TWiki web is the default web. Example: %INCLUDE{"TWiki.SiteMap"}%

  • %SEARCH{"sushi"}% : Inline search showing the search result embedded in a topic. FormattedSearch gives you control over formatting, used to create web-based applications.

  • TWikiPreferences? defines site-wide variables. Among others:
    • Line break: Write %BR% to start a new line.
    • Colored text: Write: %RED% Red %ENDCOLOR% and %BLUE% blue %ENDCOLOR% colors to get: Red and blue colors.
    • Documentation Graphics: Write: %H% Help, %T% Tip, %X% Alert to get: HELP Help, TIP Tip, ALERT! Alert. For more info see TWikiDocGraphics.

  • To "escape" a variable, prefix it with an exclamation point. Write: !%SOMEVARIABLE% to get: %SOMEVARIABLE%.

TWikiPlugin Formatting Extensions

Plugins provide additional text formatting capabilities and can extend the functionality of TWiki into many other areas. For example, the optional SpreadSheetPlugin lets you create a spreadsheet with the same basic notation used in TWiki tables.

Available Plugins are located in the Plugins web on TWiki.org. Currently enabled plugins on this TWiki installation, as listed by %PLUGINDESCRIPTIONS%:

  • DefaultPlugin: This plugin can be used to specify some simple custom rendering rules. It also renders depreciated *_text_* as bold italic text.
  • SpreadSheetPlugin: Add spreadsheet calculation like "$SUM( $ABOVE() )" to tables located in TWiki topics.
  • BibliographyPlugin: cite bibliography in one topic and get a references list automatically created.
  • CommentPlugin: Allows users to quickly post comments to a page without an edit/preview/save cycle.
  • EditTablePlugin: Edit TWiki tables using edit fields, date pickers and drop down boxes
  • InterwikiPlugin: Link ExternalSite:Page text to external sites based on aliases defined in the InterWikis topic
  • PhotoarchivePlugin: PhotoarchivePlugin? creates nice image galleries
  • RenderListPlugin: Render bullet lists in a variety of formats
  • SlideShowPlugin: Create web based presentations based on topics with headings.
  • SmiliesPlugin: Render smilies as icons, like  :-) for smile or  :cool: for cool!
  • TablePlugin: Control attributes of tables and sorting of table columns
  • TopicVarsPlugin: Set variables in arbitrary topics and refer to them from other topics within the same web
  • TreePlugin: Dynamic generation of TWiki topic trees

Check on current Plugin status and settings for this site in TWikiPreferences?.

Common Editing Errors

TWiki formatting rules are fairly simple to use and quick to type. However, there are some things to watch out for, taken from the TextFormattingFAQ:

  • Q: Text enclosed in angle brackets like <filename> is not displayed. How can I show it as it is?
    • A: The '<' and '>' characters have a special meaning in HTML, they define HTML tags. You need to escape them, so write '&lt;' instead of '<', and '&gt;' instead of '>'.
      Example: Type 'prog &lt;filename&gt;' to get 'prog <filename>'.

  • Q: Why is the '&' character sometimes not displayed?
    • A: The '&' character has a special meaning in HTML, it starts a so called character entity, i.e. '&copy;' is the © copyright character. You need to escape '&' to see it as it is, so write '&amp;' instead of '&'.
      Example: Type 'This &amp; that' to get 'This & that'.

TWiki Variables

Special text strings expand on the fly to display user data or system info

TWikiVariables are text strings - %VARIABLE% - that expand into content whenever a page is rendered for viewing. VARIABLES are replaced by data, either user-entered or automatically generated by TWiki (like the date, or the current username). There are predefined variables, and Preference variables that you can configure. You can also define custom variables, with new names and values.

Notes:

  • To leave a variable unexpanded, precede it with an exclamation point, e.g. type !%TOPIC% to get %TOPIC%.
  • Variables are expanded relative to the topic they are used in, not the topic they are defined in.

Predefined Variables

Most predefined variables return values that were either set in the lib/twiki.cfg file, when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you format the appearance of the display results.

  • TIP Take the time to thoroughly read through ALL preference variables. If you actively configure your site, review variables periodically. They cover a wide range of functions, and it can be easy to miss the one perfect variable for something you have in mind. For example, see %INCLUDINGTOPIC%, %INCLUDE%, and the mighty %SEARCH%.

This version of TWiki - 04 Sep 2004 $Rev: 1742 $ - expands the following variables (enclosed in % percent signs):

ATTACHURL -- full URL for attachments in the current topic

ATTACHURLPATH -- path of the attachment URL of the current topic

BASETOPIC -- base topic where an INCLUDE started

  • The name of the topic where a single or nested INCLUDE started - same as %TOPIC% if there is no INCLUDE
  • Syntax: %BASETOPIC%
  • Related: BASEWEB, INCLUDINGTOPIC, INCLUDE, TOPIC

BASEWEB -- base web where an INCLUDE started

  • The web name where the includes started, e.g. the web of the first topic of nested includes. Same as %WEB% in case there is no include.
  • Syntax: %BASEWEB%
  • Related: BASETOPIC, INCLUDINGWEB, INCLUDE, WEB

DISPLAYTIME -- display time

DISPLAYTIME{"format"} -- formatted display time

  • Formatted time - either GMT or Local server time, depending on setting in TWiki.cfg. Same format qualifiers as %GMTIME%
  • Syntax: %DISPLAYTIME{"format"}%
  • Example: %DISPLAYTIME{"$hou:$min"}% expands to 11:48
  • Related: DISPLAYTIME, GMTIME, SERVERTIME

ENCODE{"string"} -- encodes a string

  • Syntax: %ENCODE{"string"}%
  • Supported parameters:
    Parameter: Description: Default:
    "string" String to encode required (can be empty)
    type="entity" Encode special characters into HTML entities, like a double quote into &#034; URL encoding
    type="url" Encode special characters for URL parameter use, like a double quote into %22 (this is the default)
  • Example: %ENCODE{"spaced name"}% expands to spaced%20name
  • Related: URLPARAM

FORMFIELD{"format"} -- renders a field in the form attached to some topic

  • Syntax: %FORMFIELD{"fieldname"}%
  • Supported parameters:
    Parameter: Description: Default:
    "fieldname" The name of a TWiki form field required

Setting Preferences

  • The syntax for Preferences Variables is the same anywhere in TWiki (on its own TWiki bullet line, including nested bullets):
    [multiple of 3 spaces] * [space] Set [space] VARIABLENAME [space] = [value]
    Examples:
  • Set VARIABLENAME = value
    • Set VARIABLENAME = value

Creating Custom Variables

  • You can add your own Preference Variables for us across an entire site or a single web, using the standard Preferences syntax. Whatever you include in your Variable will be expanded on display, exactly as if it had been entered directly. You can place formatted text, page links, image paths.

Example: Create a custom logo variable the Tutorial web
  • To place a logo anywhere in a web by typing %MYLOGO%, define the Variable on the web's WebPreferences page, and upload a logo file, ex: mylogo.gif. You can upload by attaching the file to WebPreferences, or, to avoid clutter, to any other topic in the same web, ex: LogoTopic:
    • Set MYLOGO = %PUBURL%/TWiki/LogoTopic/mylogo.gif

File Attachments

Each topic can have one or more files of any type attached to it by using the Attach screen to upload (or download) files from your local PC. Attachments are stored under revision control: uploads are automatically backed up; all previous versions of a modified file can be retrieved.

What Are Attachments Good For?

File Attachments can be used to create powerful customized groupware solutions, like file sharing and document management systems, and quick Web page authoring.

Document Management System

  • You can use Attachments to store and retrieve documents (in any format, with associated graphics, and other media files); attach documents to specific TWiki topics; collaborate on documents with full revision control; distribute documents on a need-to-know basis using web and topic-level access control; create a central reference library that's easy to share with an user group spread around the world.

File Sharing

  • For file sharing, FileAttachments on a series of topics can be used to quickly create a well-documented, categorized digital download center for all types of files: documents; graphics and other media; drivers and patches; applications; anything you can safely upload!

Web Authoring

  • Through your Web browser, you can easily upload graphics (or sound files, or anything else you want to link to on a page) and place them on a single page, or use them across a web, or site-wide.
    • NOTE: You can also add graphics - any files - directly, typically by FTP upload. This requires FTP access, and may be more convenient if you have a large number of files to load. FTP-ed files can't be managed using browser-based Attachment controls. You can use your browser to create TWikiVariables shortcuts, like this %H% = HELP.

Uploading Files

  • Click on the Attach link at the bottom of the page. The Attach screen lets you browse for a file, add a comment, and upload it. The uploaded file will show up in the File Attachment table.
    • NOTE: The topic must already exist. It is a two step process if you want to attach a file to a non-existing topic; first create the topic, then add the file attachment.
    • Any type of file can be uploaded. Some files that might pose a security risk are renamed, ex: *.php files are renamed to *.php.txt so that no one can place code that would be read in a .php file.
    • The previous upload path is retained for convenience. In case you make some changes to the local file and want to upload it, again you can copy the previous upload path into the Local file field.
    • TWiki can limit the file size. This is defined by the %ATTACHFILESIZELIMIT% variable of the TWikiPreferences?, currently set at 10000 KB.
      • ALERT! It's not recommended to upload files greater than a few hundred K through a browser. Large files can be extremely slow-loading, and often time out. Use an FTP site for large file uploads.

Downloading Files

  • ALERT! NOTE: There is no access control on individual attachments. If you need control over single files, create a separate topic per file and set topic-level access restrictions for each.

Moving Attachment Files

An attachment can be moved between topics.

  • Click Manage on the Attachment to be moved.
  • On the control screen, select the new web and/or topic.
  • Click Move. The attachment and its version history are moved. The original location is stored as topic Meta Data.

Deleting Attachments

Move unwanted Attachments to web Trash, topic TrashAttachment.

Linking to Attached Files

  • To reference an attachment located in another topic, enter:
    • %PUBURL%/%WEB%/OtherTopic/Sample.txt (if it's within the same web)
    • %PUBURL%/Otherweb/OtherTopic/Sample.txt (if it's in a different web)

  • Attached HTML files and text files can be inlined in a topic. Example:
    1. Attach file: Sample.txt
    2. Edit topic and write text: %INCLUDE{"%ATTACHURL%/Sample.txt"}%

  • GIF, JPG and PNG images can be attached and shown embedded in a topic. Example:
    1. Attach file: Smile.gif
    2. Edit topic and write text: %ATTACHURL%/Smile.gif
    3. Preview: text appears as Smile.gif, an image.

File Attachment Contents Table

Files attached to a topic are displayed in a directory table, displayed at the bottom of the page, or optionally, hidden and accessed when you click Attach.

Topic FileAttachment . { | | Move attachment | Cancel }

  • The first table is a list of all attachments, including their attributes. An h means the attachment is hidden, it isn't listed when viewing a topic.

  • The second table is all the versions of the attachment. Click on View to see that version. If it's the most recent version, you'll be taken to an URL that always displays the latest version, which is usually what you want.
    • To change the comment on an attachment, enter a new comment and then click Change properties. Note that the comment listed against the specific version will not change, however the comment displayed when viewing the topic does change.
    • To hide/unhide an attachment, enable the Hide file checkbox, then click Change properties.

Known Issues

  • Unlike topics, attachments are not locked during editing. As a workaround, you can change the comment to indicate an attachment file is being worked on - the comment on the specific version isn't lost, it's there when you list all versions of the attachment.


TWiki Forms

Form-based input in topics, with name/value pairs stored as Meta Data variables; choose one of multiple forms per web & topic

Overview

By adding form-based input to freeform content, you can structure topics with unlimited, easily searchable categories. When forms are enabled for a web and selected in a topic, a single form appears in edit mode, and the contents are rendered as a table when viewed on the display page. You can define unlimited forms per web. For each topic, you can select a template if more than one is defined, or remove forms entirely. Form input values are stored as TWikiMetaData?; all data is saved.

Form Templates replace TWikiCategoryTables from the 01-Dec-2000 version of TWiki. - see #FormsVsCategoryTables

Defining a Form Template

A Form Template is simply a page containing your form, defined as a table where each row is one form field.

Form Template Elements

  • form template - a set of fields defining a form (replaces category table definition)
    • A web can use one or more form templates
  • form - a topic containing additional meta data (besides the freeform TEXTAREA) that categorizes the content (replaces category table)
    • Within a form-enabled web, individual topics can have a form or no form
  • form field - a named item in a form (replaces category item name)
  • field type - selects the INPUT type:
    Input type Type field Size field Value field
    One or more checkboxes checkbox number of checkboxes per line comma list of checkbox labels
    One or more checkboxes, plus Set and Clear buttons checkbox+buttons (same) (same)
    Read-only label text label 1 (unused)
    One or more radio buttons radio number of radio buttons per line comma list of checkbox labels
    Drop-down menu or scrollable box select 1 for drop down, 2 and up for scrollable box comma list of options
    A one-line text field text text box width in number of characters (unused)
    A text box; size is 40x10 (columns x rows) textarea columns x rows, e.g. 40x6 (unused)
  • field value - one or more values from a fixed set (select, checkbox, radio type) or free-form (text). (replaces category item value)

Defining a Form in One Topic

  1. Create a new topic with your form name: YourForm, ExpenseReport, InfoCategory, RecordReview, whatever you need.
  2. Create a TWiki table, with each column head representing one element of an entry field: Name, Type, Size, Values, and Tooltip message (see sample below).
  3. For each field, fill in a new line; for the type of field, select from the list.
  4. Save the topic (you can later choose to enable/disable individual forms).

Example: WebForm
| *Name* | *Type* | *Size* | *Values* | *Tooltip message* |
| TopicClassification | select | 1 | NoDisclosure, PublicSupported, PublicFAQ | blah blah... |
| OperatingSystem | checkbox | 3 | OsHPUX, OsLinux, OsSolaris, OsWin | blah blah... |
| OsVersion | text | 16 | | blah blah... |

Name Type Size Values Tooltip message
TopicClassification select 1 NoDisclosure, PublicSupported, PublicFAQ blah blah...
OperatingSystem checkbox 3 OsHPUX, OsLinux, OsSolaris, OsWin blah blah...
OsVersion text 16   blah blah...

Defining a Form with Multiple Topics

Forms can also be defined by using form templates that retrieve field values from one or more separate topics:

  • A FormTemplate topic defines the Form, ex: YourFormTemplate.
  • For each field that has a value list - select, radio, checkbox - can use separate topic to define the available values.

Example: WebFormTemplate

  • WebFormTemplate main definition:
     
    Name Type Size Values Tooltip message
    TopicClassification select 1   blah blah...
    OperatingSystem checkbox 3   blah blah...
    OsVersion text 16   blah blah...

    ALERT! Leave the Values field blank.

  • TopicClassification field value definition:
     
    Name Type Tooltip message
    NoDisclosure option blah blah...
    PublicSupported option blah blah...
    PublicFAQ option blah blah...

  • Implementation Notes: This format allows you to define field items with or without WikiNames, depending on your needs.
    • Topics can be protected in the usual manner, using TWikiAccessControl, to limit who can change the form template and/or individual value lists.
    • [[...]] links can be used to force a link (at present, the [[...][...]] format is not supported).
    • The Tooltip message column is used as a tooltip for the field name (only if field name is a WikiName) - you only see the tooltip In edit.
    • The first item in the list is the default item. Alternative initial values can be set in a topic template, like WebTopicEditTemplate, with field=value, or, for checkboxes, field=1.
    • The topic definition is not read when a topic is viewed.

Enabling Forms by Web

Forms are enabled on a per web basis. The WEBFORMS variable in WebPreferences is optional and defines a list of possible form templates. Example:

  • Set WEBFORMS = BugForm, FeatureForm, BookLoanForm

  • With WEBFORMS enabled, an extra button is added to the edit view. If the topic doesn't have a Form, an Add Form button appears at the end of the topic. If a Form is present, a Change button appears in the top row of the Form. The buttons open a screen that enables selection of a form specified in WEBFORMS, or the No form option.

Including Forms in New Topics

  • A default Form Template (new topics get this default form) can be provided by creating the WebTopicEditTemplate topic in a web and adding a form to it. Initial Form values can be set there.

  • Additionally a new topic can be given a Form using the formtemplate parameter in the URL. Initial values can then be provided in the URLs or as form values:
    • other than checkboxes: name, ex: ?BugPriority=1
    • checkbox: namevalue=1, ex: ?ColorRed=1.
      Boxes with a tick must be specified.

Setting Up Multiple Form Options

  • The optional WEBFORMS variable defines alternative forms that can be selected by pressing Change in edit mode.

  • A topic template can use any form.

  • New topics with a form are created by simple HTML forms asking for a topic name. For example, you can have a SubmitExpenseReport topic where you can create new expense reports, a SubmitVacationRequest topic, and so on. These can specify the required template topic with its associated form.

Form Data Storage

The form topic name, fields and values are stored as TWikiMetaData? - the order of the field/value pairs is the same as in the template.

Using Form Data

TWikiForms accept user-input data, stored as TWikiMetaData?. Meta data also contains program-generated info about changes, attachments, etc. To find, format and display form and other meta data, see TWikiMetaData?, SEARCH and METASEARCH variables in TWikiVariables, and TWiki Formatted Search for various options.

Main Changes from Category Tables

The Form Template system is a more powerful, flexible replacement for the original TWikiCategoryTable. Data from existing category tables can be imported directly.

Form Templates Category Tables
defined in topics defined in templates
many forms per web one table per web
saved as Meta Data saved as HTML
Change & Add Form buttons UseCategory radio button

Importing Category Table Data

On upgrading from the previous TWiki, a Form Template topic has to be built for each web that used a Category Table, recreating the fields and values from the old twikicatitems.tmpl. The replacement Form Template must be set as the first item in the WebPreferences variable WEBFORMS. If missing, pages will display, but attempting to edit results in an error message.

The new Form Template system should work with old Category Table data with no special conversion. Data is assigned to Meta variables the first time an imported topic is edited and saved in the new system.

TIP NOTE: If things aren't working correctly, there may be useful entries in data/warning.txt.

Using Forms For Settings

Example process to change your WebPreferences to use forms instead of {3 spaces}* Set statements:

  1. create WebPrefencesForm topic
  2. fill it with a table like this:
    | *Name*|*Type*|*Size*|*Value*|*Tooltip message*|*Attributes*|
    | WEBTOPICLIST |textarea| |     | List of topics of the %WEB% web |S|
    | SITEMAPLIST  |select  |3| on, | list this web in the Site Map  |S|
    | SITEMAPWHAT  |textarea| |     | short web summary             |S|
    | WEBBGCOLOR   |text    |8|     | Web specific background color |S|
    etc...
  3. Edit WebPreferences and:
    • Add or Change the form to WebPrefencesForm
    • add WebPrefencesForm to the Set WEBFORMS line
    • Save
  4. Edit WebPreferences, jump straight down to the form ignoring all the textarea stuff, and set as you like
  5. if everything works as you like it, you can delete the Set statements (the form overrides set if they are both used).

Notes:

If it isn't working, double check that the S attribute has been specified (S for Setting). If you change the form, the changes will not take affect until you edit and save the preferences' topics again.

Using the TWiki:Plugins.EditTablePlugin on WebPreferencesForm makes adding new prefedrences a breeze.

A possibly unwanted side effect for using forms for the SKINS setting in their personal user topic: because the User Preferences are final you can't have different skins for different webs as the user's setting always wins. A workaround is to simply omit SKIN in the form.

Another example, this one using EditTablePlugin, source:

%EDITTABLE{ header="|*Name*|*Type*|*Size*|*Values*|*Tooltip message*|*Attributes*|" format="|text,20|text,20|text,20|text,20|text,20|text,1|" }%

Result (after some editing):

TWiki Formatted Search Results

Inline search feature allows flexible formatting of search result

The %SEARCH{...}% variable documented in TWikiVariables has a fixed format for the search result, that is, a table consisting of topic names and topic summaries. Use the format="..." parameter to specify a customized format of the search result. The string of the format parameter is typically a bullet list or table row containing variables (such as %SEARCH{ "food" format="| $topic | $summary |" }%).

Syntax

Two parameters can be used to specify a customized search result:

1. header="..." parameter

Use the header parameter to specify the header of a search result. It should correspond to the format of the format parameter. This parameter is optional.
Example: header="| *Topic:* | *Summary:* |"

2. format="..." parameter

Use the format parameter to specify the format of one search hit.
Example: format="| $topic | $summary |"

Variables that can be used in the format string:

Name: Expands To:
$web Name of the web
$topic Topic name
$topic(20) Topic name, "- " hyphenated each 20 characters
$topic(30, -<br />) Topic name, hyphenated each 30 characters with separator "-<br />"
$topic(40, ...) Topic name, shortended to 40 characters with "..." indication
$parent Name of parent topic; empty if not set
$parent(20) Name of parent topic, same hyphenation/shortening like $topic()
$text Formatted topic text. In case of a multiple="on" search, it is the line found for each search hit.
$locked LOCKED flag (if any)
$date Time stamp of last topic update, e.g. 24 Aug 2019 - 11:48
$isodate Time stamp of last topic update, e.g. 2019-08-24T11:48Z
$rev Number of last topic revision, e.g. 1.4
$username Login name of last topic update, e.g. jsmith
$wikiname Wiki user name of last topic update, e.g. JohnSmith
$wikiusername Wiki user name of last topic update, like Main.JohnSmith
$createdate Time stamp of topic revision 1.1
$createusername Login name of topic revision 1.1, e.g. jsmith
$createwikiname Wiki user name of topic revision 1.1, e.g. JohnSmith
$createwikiusername Wiki user name of topic revision 1.1, e.g. Main.JohnSmith
$summary Topic summary
$formname The name of the form attached to the topic; empty if none
$formfield(name) The field value of a form field; for example, $formfield(TopicClassification) would get expanded to PublicFAQ. This applies only to topics that have a TWikiForm
$formfield(name, 10) Form field value, "- " hyphenated each 10 characters
$formfield(name, 20, -<br />) Form field value, hyphenated each 20 characters with separator "-<br />"
$formfield(name, 30, ...) Form field value, shortended to 30 characters with "..." indication
$pattern(reg-exp) A regular expression pattern to extract some text from a topic (does not search meta data; use $formfield instead). In case of a multiple="on" search, the pattern is applied to the line found in each search hit.
• Specify a RegularExpression that covers the whole text (topic or line), which typically starts with .*, and must end in .*
• Put text you want to keep in parenthesis, like $pattern(.*?(from here.*?to here).*)
• Example: $pattern(.*?\*.*?Email\:\s*([^\n\r]+).*) extracts the email address from a bullet of format * Email: ...
• This example has non-greedy .*? patterns to scan for the first occurance of the Email bullet; use greedy .* patterns to scan for the last occurance
• Limitation: Do not use .*) inside the pattern, e.g. $pattern(.*foo(.*)bar.*) does not work, but $pattern(.*foo(.*?)bar.*) does
• Note: Make sure that the integrity of a web page is not compromised; for example, if you include an HTML table make sure to include everything including the table end tag
$n or $n() New line
$nop or $nop() Is a "no operation". This variable gets removed; useful for nested search
$quot Double quote ("). Alternatively write \" to escape it
$percnt Percent sign (%)
$dollar Dollar sign ($)

Examples

Table showing form field values of topics with a form

In a web where there is a form that contains a TopicClassification field, an OperatingSystem field and an OsVersion field we could write:

| *Topic:* | *OperatingSystem:* | *OsVersion:* |
%SEARCH{ "[T]opicClassification.*?value=\"[P]ublicFAQ\"" scope="text" regex="on" nosearch="on" nototal="on" format="| [[$topic]] | $formfield(OperatingSystem) | $formfield(OsVersion) |" }%

Nested Search

Search can be nested. For example, search for some topics, then form a new search for each topic found in the first search. The idea is to build the nested search string using a formatted search in the first search.

Here is an example. Let's search for all topics that contain the word "culture" (first search), and let's find out where each topic found is linked from (second search).

  • First search:
    • %SEARCH{ "culture" format="   * $topic is referenced by: (list all references)" nosearch="on" nototal="on" }%
  • Second search. For each hit we want this search:
    • %SEARCH{ "(topic found in first search)" format="$topic" nosearch="on" nototal="on" separator=", " }%
  • Now let's nest the two. We need to escape the second search, e.g. the first search will build a valid second search string. Note that we escape the second search so that it does not get evaluated prematurely by the first search:
    • Use $percnt to escape the leading percent of the second search
    • Use \" to escape the double quotes
    • Use $dollar to escape the $ of $topic
    • Use $nop to escape the }% sequence

Write this:

%SEARCH{ "culture" format="   * $topic is referenced by:$n      * $percntSEARCH{ \"$topic\" format=\"$dollartopic\" nosearch=\"on\" nototal=\"on\" separator=\", \" }$nop%" nosearch="on" nototal="on" }%

To get this:

Note: Nested search can be slow, especially if you nest more then 3 times. Nesting is limited to 16 levels. For each new nesting level you need to "escape the escapes", e.g. write $dollarpercntSEARCH{ for level three, $dollardollarpercntSEARCH{ for level four, etc.

Most recently changed pages

Write this:

%SEARCH{ "\.*" scope="topic" regex="on" nosearch="on" nototal="on" order="modified" reverse="on"  format="| [[$topic]] | $wikiusername  | $date |" limit="7" }%

To get this:

Search with conditional output

A regular expression search is flexible, but there are limitations. For example, you cannot show all topics that are up to exactly one week old, or create a report that shows all records with invalid form fields or fields within a certain range, etc. You need some additional logic to format output based on a condition:

  1. Specify a search which returns more hits then you need
  2. For each search hit apply a spreadsheet formula to determine if the hit is needed
  3. If needed, format and output the result
  4. Else supress the search hit

This requires the TWiki:Plugins.SpreadSheetPlugin. The following example shows all topics that are up to exactly one week old.

Write this:

%CALC{$SET(weekold, $TIMEADD($TIME(), -7, day))}%
%SEARCH{ "." scope="topic" regex="on" nosearch="on" nototal="on" order="modified" reverse="on" format="$percntCALC{$IF($TIME($date) < $GET(weekold), <nop>, | [[$topic]] | $wikiusername | $date | $rev |)}$percnt" limit="100" }%

  • The first line sets the weekold variable to the serialized date of exactly one week ago
  • The SEARCH has a deferred CALC. The $percnt makes sure that the CALC gets executed once for each search hit
  • The CALC compares the date of the topic with the weekold date
  • If topic is older, a <nop> is returned, which gets removed at the end of the TWiki rendering process
  • Otherwise, the search hit is formatted and returned

To get this:

Embedding search forms to return a formatted result

Use an HTML form and an embedded formatted search on the same topic. You can link them together with an %URLPARAM{"..."}% variable. Example:

Write this:

<form action="%SCRIPTURLPATH%/view%SCRIPTSUFFIX%/%WEB%/%TOPIC%">
Find Topics: 
<input type="text" name="q" size="32" value="%URLPARAM{"q"}%" />
<input type="submit" value="Search" />
</form>
Result:
%SEARCH{ search="%URLPARAM{"q"}%" format="   * $web.$topic: %BR% $summary" nosearch="on" }%

To get this:

Find Topics:
Result: Number of topics: 0

TWiki Site Tools

Utilities for searching, navigation, and monitoring site activity

TWikiSiteTools include utilities for navigating, searching and keeping up with site activity. Preferences can be configured by web or site-wide. You are currently in the TWiki web. In particular, TWiki provides two highly configurable, automated site monitoring tools, WebNotify, to email alerts when topics are edited, and WebStats, to generate detailed activity reports.

WebNotify Recent Changes Alert

Each TWiki web has an automatic email alert service that sends a list of recent changes on a preset schedule, like once a day. Users can subscribe and unsubscribe using WebNotify in each web. The Perl script mailnotify is called by a background process at regular intervals. The script sends an automated email to subscribed users if topics were changed in a web since the script was last run.

Format: TWiki handles entries in bullet list (<space><space><space>*) format containing the WikiName of a user; a WikiName with e-mail address; or a TWikiGroup. Examples:

  • Main.FredBloggs
  • Main.FredBloggs - secondary@home.com
  • Main.EngineeringGroup

The first entry is the default form, the notification gets sent to the e-mail address specified in the user's home page. The second entry lists an alternative e-mail address. The third entry specifies a group, the notification gets sent to each member of the group.

You can also use %MAINWEB% instead of Main, but this is not necessary even if you have renamed the main web by configuring $mainWebname in TWiki.cfg.

Configuring Outgoing Mail

TWiki will use the Net::SMTP module if it is installed on your system. Set this with the SMTPMAILHOST variable in TWikiPreferences?.

The notify e-mail uses the default changes.tmpl template, or a skin if activated in the TWikiPreferences?.

mailnotify also relies on two hidden files in each TWiki/data/[web] directory: .changes and .mailnotify. Make sure both are writable by your web server process. .changes contains a list of changes; go ahead and make this empty. .mailnotify contains a timestamp of the last time notification was done.

You can use an external mail program, like sendmail, if the Net::SMTP module is not installed. Set the program path in $mailProgram in TWiki.cfg.

  • HELP Net::SMTP can be easily disabled (ex: if there is an installation error) by setting SMTPMAILHOST in TWikiPreferences? to an empty value.

  • TIP You can set a separate SMTPSENDERHOST variable to define the mail sender host (some SMTP installations require this).

Setting the Automatic Email Schedule

For Unix platforms: Edit the cron table so that mailnotify is called in an interval of your choice. Please consult man crontab of how to modify the table that schedules program execution at certain intervals. Example:

% crontab -e
0 2 * * * (cd /path/to/twiki/bin; ./mailnotify -q)
The above line will run mailnotify nightly at 02:00. The -q switch suppresses all normal output.

For ISP installations: Many ISPs don't allow hosted accounts direct cron access, as it's often used for things that can heavily load the server. Workaround scripts are available.

On Windows NT/2000: You can use a scheduled task if you have administrative privileges. Note: AT on an NT machine is pretty limited. Microsoft lists several third-party replacements. TWiki:Codev/CronTabWin is a free scheduler for Windows.

WebStatistics Site Usage Log

You can generate a listing manually, or on an automated schedule, of visits to individual pages, on a per web basis. Compiled as a running total on a monthly basis. Includes totals for Topic Views, Topic Saves, Attachment Uploads, Most Popular Topics with number of views, and Top Contributors showing total of saves and attachment uploads. Previous months are saved.

Configuring for Automatic Operation

  • You can automatically generate usage statistics for all webs. To enable this:
    • Make sure variable $doLogTopicView, $doLogTopicSave and $doLogTopicUpload in TWiki.cfg are set. This will generate log file entries (see below).
    • The WebStatistics topic must be present in all webs where you want to have statistics. You can use the topic in the Main web as a template.
    • Call the twiki/bin/statistics script from a cron job, once a day is recommended. This will update the WebStatistics topics in all webs.
    • Attention: The script must run as the same user as the CGI scripts are running, which is user nobody on many systems. Example crontab entry:
      0 0 * * * (cd /path/to/TWiki/bin; ./statistics >/dev/null 2>&1)
    • There is a workaround in case you can't run the script as user nobody : Run the utility twiki/bin/geturl in your cron job and specify the URL of the twiki/bin/statistics script as a parameter. Example:
      0 0 * * * (cd /path/to/TWiki/bin; ./geturl mydomain.com /urlpath/to/TWiki/bin/statistics >/dev/null 2>&1)

Generating Statistics Manually by URL

  • The twiki/bin/statistics script can also be executed as a CGI script, just enter the URL in your browser. Examples:
    • Update current month for all webs:
      http://mydomain.com/twiki/bin/statistics
    • Update current month for Main web only:
      http://mydomain.com/twiki/bin/statistics/Main
    • Update January 2000 for Main web:
      http://mydomain.com/twiki/bin/statistics/Main?logdate=200001

Log File Details

TWiki generates monthly log files which are used by the statistics

WebSearch

WebSearch is an extremely fast and flexible search facility, part of the core TWiki feature set. Options include:

  • topic title or full-text search
  • regular expressions
  • search within web or site-wide
  • index-style A-Z alphabetical listing sorted topic title
  • many more

See also: TWikiVariables for including hard-coded searches in text.

WebChanges

To check for the most recently edited topics while on-site, use the WebChanges link, usually located on the upper toolbar. It lists the most recently modified topics, newest first, along with the first couple of lines of the page content.

This is simply a preset SEARCH. The number of topics listed by the limit parameter.:

%SEARCH{".*" web="Tutorial" regex="on" nosearch="on" order="modified" 
reverse="on" limit="50"}%

WebIndex

WebIndex lists all web topics in alphabetical order, with the first couple of lines of text. This is simply a preset SEARCH:

%SEARCH{"\.*" scope="topic" regex="on" nosearch="on"}%

Managing Topics

Browser-based rename, move, and delete for individual topics

Overview

You can use browser-based controls to change a topic's name, move it to another TWiki web, or delete it to a hidden Trash web.

How to Rename/Move/Delete a Topic

  1. Click on [More] (bottom right of page) on the topic to be changed, then, in the new screen, on [Rename/move]. You can now rename and/or move/delete in one operation:
  2. Move/Delete: Select the target web if other than the current web - choose Trash to delete a topic.
  3. Rename: Enter the new topic name - default is current name
    ALERT! NOTE: You'll be warned if any of the topics to be affected are locked (being edited), or if there is a name conflict.
  4. Prevent updates by unchecking individual items on the list of referring links - these topics will NOT to be updated with the new name (by default, all referring links will be updated).
  5. Click on [Rename/Move]: the topic will be renamed and links to the topic updated as requested.
    • If any of the referring pages are locked then they will be listed: you can correct these later by again pressing [Rename/Move].
    • HELP There is a Put back feature that allows you to undo a Rename/Move/Delete - an instruction line and undo link will appear at the bottom of the modified topic. This allows you to revert from the last modification only.

Deleted Topics: How to Clear the Trash

Deleted topics are moved to a special Trash web - they are NOT physically erased from the server. All webs share Trash - in case of a name conflict with a topic already Trash, the user is alerted and asked to choose a new name.

The Trash web should be be cleared periodically, by archiving (saving) the text and RCS files if required (recommended), then deleting them from the Trash directory.

  • ALERT! This can only be done from on the server, not through the browser.
    • TIP Since simple FTP access to the Trash directory is all that's required for maintenance, it's possible to grant Trash admin privileges to multiple users, while strictly limiting server access.

Redirecting from an Old Topic

You can use TWikiMetaData? to place a command in the WebTopicViewTemplate and WebTopicNonWikiTemplate that will indicate that a topic has been moved by searching for the tag %META:TOPICMOVED{...}%. Customize something like this:

%<nop>METASEARCH{type="topicmoved" web="%WEB%" topic="%TOPIC%" 
title="This topic used to exist and was moved to: "}%

How Rename/Move Works

  1. %SEARCH%, with a special template, finds and displays all occurrences of the topic name in other topics, site-wide. These referring links are by default automatically changed to the new topic and/or web name. This includes relevant TWikiMetaData? definitions.
    • User can omit one or more topics from the update list by unchecking them.
    • <pre> and <verbatim> are honoured - no changes are made to text within these areas.
  2. The topic is moved (if locks allow).
  3. References are changed (locks and permissions permitting).
  4. Any referring topics that can't be changed due to locks are listed - user can take note and change them at another time.

How Referring Topics Are Found

Referring topics are found using the %SEARCH% variable - see the template searchrenameview.tmpl. First, matching topics in the current web are listed - matches are to topic. Next, all webs (including the current one) are listed that match web.topic. Because %SEARCH% is used, webs marked in WebPreferences as NOSEARCHALL will not show up in the search for references to the topic being changed.

Changed references are kept are as short as possible, ex: topic is used in preference to web.topic.

Effect of User Access Settings

User permissions affect the Rename function in various ways. To rename a topic, you need both ALLOWTOPICCHANGE and ALLOWTOPICRENAME permission for that topic. To alter referring topics, you need change permission. See TWikiAccessControl for information on setting up access permissions.

Special Considerations

Consider carefully whether to make browser-based Rename/Move/Delete widely available, or to restrict it to an administrator/moderator group. Allowing all users to easily manipulate topics can be extremely useful in refactoring a busy web or site. However, there are at least two significant potential drawbacks to take into account:

  • When referring links are updated, the modified topics appear in WebChanges, creating the impression that editorial changes were made. This can undermine the usefulness of WebChanges.
  • Due to current limitations, fairly heavy use of Rename/Move/Delete functions can lead to an accumulation of minor technical problems (ex: broken links) and usability issues (ex: user confusion). If Rename... is used heavily, these negatives will obviously increase, in number and effect.

Ultimately, the size, objectives, and policies of your TWiki site, the real-world behavior of your user group, and most importantly, the initial TWiki site management leadership, will determine the most effective implementation of this feature, and the success of the site overall.

Known Issues

Rename/Move is fairly complicated due to the dynamic generation of links. Ideally, it would be possible to run the required part of rendering in a way that would allow identification of the text to be changed. Unfortunately, these hooks don't exist in TWiki at present. Instead, %SEARCH% is used with a special template to show the text to be changed, and the selected topics are then altered. One drawback is that search can show matches that will not be updated due to case differences. Other mismatches with actual rendered output are also possible as the approaches are so different.

The following shows some limitations of square bracket processing.

[[Old Topic]]  => [[NewTopic][Old Topic]]
[[old topic]]  => [[NewTopic][old topic]]
[[old t opic]] => not changed
[[OldTopic]]   => [[NewTopic]]

Managing Webs

Adding webs is a web based operation; renaming and deleting webs are manual operations done directly on the server

Overview

A TWikiSite is divided into webs; each one represents one subject, one area of collaboration. Administrators can add/rename/delete webs.

Choose Web Template

There are two methods used to create a new web. First you can use a specially designed TemplateWeb?. This is an invisible web that begins with an underscore "_" character. All topics in the _default template web will be copied into your new web.

The second method is to use an existing web as a template web. This may be useful if you already have a web that you like to use as a starting point. Only topics that have names beginning with Web... (like "WebHome", "WebNotify", etc.) are copied.

In either case you will want to be sure to verify that your new web has all the custom modifications that you desire.

Adding a New Web

Create a new web by filling out this form. Note: It is not recommended to create a new web for each little project. You can organize content within a web using TWikiForms and FormattedSearch. Cross-linking topics and search is easier if there are only a few larger webs.
Name of new web: Enter a short name of up to 10 characters. The name must start with an upper case letters, followed by optional upper or lower case letters or numbers
Based on web: Select a TemplateWeb?
Web color: Enter a StandardColors? code for the web
Description:
 
 

Enter a short description of the web. Write Web.TopicName instead of just TopicName if you include links. This will list the web in the SiteMap (leave field empty if you prefer not to update the directory.)
Use to...
 

Continue the sentence describing the intended use. This is also for the SiteMap
Exclude web from "search all": No   Yes Specify if you want to exclude the web from a "search all webs" search. Note that the SiteMap will not list the web if you select Yes.
 

Notes:

  • Attachments will NOT get copied over along with their topics
  • The manage script while creating the new web will update the following variables in the WebPreferences: WEBBGCOLOR, SITEMAPLIST, SITEMAPWHAT, SITEMAPUSETO and NOSEARCHALL. These variables are used to dynamically generate the SiteMap?
  • This script does not edit the TWiki.TWikiPreferences file to update the WIKIWEBLIST. This must be done by hand
  • As of TWiki Release 01 Sep 2004, a web name can be a WikiWord. Prior to that it could be only UPPER or UPPERlower. A side effect of this is that if you do use a wiki name, %WEB% must be written as <nop>%WEB% or else it will try to link to a non-existing topic of that name

Renaming or Deleting a Web

Renaming or deleting a web requires direct access to the installation files on the host server. There are currently no browser-based equivalents of the Rename/move/delete topic tools for working with webs.

  1. Prepare your site: Search each web for links to the target web, searching topic text for Oldwebname., including the dot so you'll find references like Oldwebname.SomeTopic
    • Make changes as required, to Newwebname.SomeTopic or better yet, to %MAINWEB%.SomeTopic
  2. Edit the TWikiPreferences? topic: Rename or delete the web from the WIKIWEBLIST variable
  3. Login to the TWiki server, via Telnet or FTP
  4. Go to twiki/data and rename or remove the web directory
  5. Go to twiki/templates and rename or remove the web directory if present
  6. Go to twiki/pub and rename or remove the web directory if present

Renaming the MAINWEB

If you plan to rename the Main web, remember that TWiki stores user and group topics in %MAINWEB%, default named Main. That means, every WikiName signature - Main.SomeUserName - points to it and would need updating (unless the variable, %MAINWEB%.SomeUserName, is used throughout).

Manage Users

Register users on your TWiki site; change/reset/install passwords; remove user accounts

Authentication and Access Control

  • TWikiUserAuthentication? describes options of user authentication
  • TWikiAccessControl describes how to define groups and how to restrict access to content

Register User

  • TWikiRegistration? is for users to fill out a form
  • NewUserTemplate? can be changed to customize user home pages

Change, Reset and Install Passwords

  • ChangePassword? is for users who remember their password
  • ResetPassword? is for users who do not remember their password; they are asked to send a request to the site administrator to install a new password
  • InstallPassword? is for the site administrator to install a password

Removing User Accounts

To remove a user account:

  1. Edit the data/.htpasswd file to delete their entry (only applies if you are using a .htpasswd file)
  2. Remove the FredQuimby line from the Main.TWikiUsers topic
  3. Remove user from all groups and from all the ALLOWWEB/ALLOWTOPIC... declarations, if any.
    Note: Otherwise this is a security hole as the first one to re-register with this name will be granted the permissions of the previous user.
  4. [optional] Remove their topic files: data/Main/FredQuimby.txt and data/Main/FredQuimby.txt,v

Note: Consider leaving the user topic file in place so their past signatures and revision author entries don't end up looking like AnUncreatedTopic?. If you want to make it clear the user is inactive on your site (e.g. PeterThoeny) or has been banished add a note to that effect and write protect the page (TWikiAccessControl). The existance of the UserName topic prevent that user name from being re-used.
