Attach Content Plugin

Saves dynamic topic text to an attachment


This plugin puts any text between a %STARTATTACH{"filename"}% and %ENDATTACH% into an attachment with the given filename.

Pass filename, topic, web or comment as parameters.

The plugin refreshes the attachment when the topic is saved, or viewed.

This plugin is written specifically to be able to put css into topic(s) and still be able to have efficient stylesheets: i.e., without the overhead of TWiki processing. The feature can be used for many other things where you want TWiki to generate a plain text file a smart way.
For example: write a SEARCH in a topic and save the search results to an XML file. The XML data can be used for efficient look-up.

Syntax Rules



You can pass a number of parameters:


Parameter Description Default Example
topic Topic to save the attachment to. none (the current topic is used) topic="WebHome"
web Web where the save topic is located. none (the current Web is used) web="Main"
comment Attachment comment text. the default ATTACHCONTENTCOMMENT text is defined in the plugin Configuration settings comment="User data as of %DATE%"
hide Use hide="on" to hide the attachment in normal topic view. off hide="on"
keeppars Keep paragraph <p /> tags, <nop> tags, and square bracket type links The default KEEPPARS setting is defined in the plugin Configuration settings keeppars="on"
attachonview Do/not do action in view The default ATTACHONVIEW setting is defined in the plugin Configuration settings ) attachonview="1"

Special note on use of attachview

If the global flag is enabled (using configure), attachments are saved every time on page view which could

  • slow down page views
  • increase server load
  • makes pages look updated even if there is no update (recent changes and e-mail notification)
  • saves pages regardless of access control (for example as TWikiGuest if not logged in)

The attachview parameter allows a targeted save on view, to apply only on the pages that need this feature


Creating a color scheme

See: PatternSkinColorSettings. This topic uses AttachContentPlugin to write a CSS file for colors. Color values are set dynamically in the topic. On topic save the CSS file is attached to the topic and can be referred to using variable USERCOLORSURL.

User data XML

Update user data XML

%STARTATTACH{"userdata.xml" comment="User data as of %DATE%"}%
<?xml version="1.0" encoding="ISO-8859-1"?>
%SEARCH{ "[F]irstName.*value=.*()" web="%MAINWEB%" type="regex" nonoise="on" excludetopic="UserForm,TWikiContributor,TWikiGuest,UnknownUser" format="<user><firstname><![CDATA[$formfield(FirstName)]]></firstname><lastname><![CDATA[$formfield(LastName)]]></lastname><url><![CDATA[%SCRIPTURL{view}%/%WEB%/$topic]]></url></user>" }%

Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, i.e. %CACHECONTENTPLUGIN_SHORTDESCRIPTION%

  • One line description, is shown in the TextFormattingRules topic:
    • Set SHORTDESCRIPTION = Saves dynamic topic text to an attachment

  • Debug plugin: (This needs to be set up in configure. This setting will have no effect. See output in data/debug.txt)
    • Set DEBUG = 0
