Topic Create Plugin

This Plugin allows you to automatically create topics or attach files at topic save time. This is typically used by Foswiki applications to create a set of template based topics.

TOPICCREATE - Automatically Create a Set of Foswiki Topics

  • The %TOPICCREATE{}% macro is useful for creating topics based on templates
  • Example scenario: You have a notebook application where users can create new notebooks based on a notebook template topic. Each time a user creates a new notebook you would like to create a set of child topics, each based on a separate template.
  • Syntax: %TOPICCREATE{ <attributes> }%
  • Attributes recognized
    Attribute Meaning Valid input Default
    template="" Name of Foswiki topic to be used as template Any valid Foswiki topic (required)
    topic="" Name of new Foswiki topic to create Any valid topic name (required)
    parent="" Parent of the newly created topic Any existing topic Current topic
    disable="" Name of the template topic containing this use of TOPICCREATE Any valid topic name (WikiWord) recommended
    <anything else>="" Any other parameters are passed to a child topic to initialize any urlparams. Any string None
  • The action to create the Foswiki topic will not occur until one hits the Save Changes button in preview
  • The %TOPICCREATE{}% macro will be removed upon saving of the topic
  • Any attachments that are in the template will also be copied to the new topic
  • %TOPICCREATE% is recursive
  • Write %TOPICCREATE{ template="MyTemplate" topic="%TOPIC%MyNewTopicName" MyParameterName="MyParameterValue" Hello="Goodbye" }% to create a foswiki topic based on another topic MyTemplate with the name %TOPIC%MyNewTopicName. Any %URLPARAM{}% with the name MyParameterName and Hello present in MyTemplate will be replaced with MyParameterValue and Goodbye.
  • To prevent the action from happening in your template topic you should either include the disable argument, or escape it: %TOPICCRE%NOP%ATE{...}%. The %NOP% gets removed when a topic gets instantiated based on a template.

TOPICATTACH - Automatically Copy Attachments to a Topic

  • Example scenario: You have a template topic and would like to attach a file whose content or name is determined by URL parameters at topic creation time. This is usually done for a topic that was just created via TOPICCREATE as described above.
  • Syntax: %TOPICATTACH{ <attributes> }%
  • Attributes recognized
    Attribute Meaning Valid input Default
    fromtopic="" Topic (or Web.Topic) that contains the attachment Any valid Foswiki topic (required)
    fromfile="" The attachment to copy from Any attached file from fromtopic (required)
    disable="" Name of the template topic containing this use of TOPICATTACH Any valid topic name (required)
    comment="" Comment to appear for the attachment within this topic, replacing the comment that was in the fromtopic a one line string {omit parameter if no change desired}
  • Write %TOPICATTACH{ fromtopic="SourceTopic" fromfile="Sample.jpg" name="Snoopy.jpg" disable="..."}% to attach Sample.jpg from topic SourceTopic as Snoopy.jpg
  • The parameter value comment is used to change the comment (description) that shows for the topic in the table of attachments
  • The "hidden" attribute of the topic is removed: the attachment can be hidden in the fromtopic if desired
  • The fromtopic can specify a different web if desired. For example Foswiki.SomeTemplate would be valid as a fromtopic
  • To prevent the action from happening in your template topic you must provide the disable parameter with the topic name containing the %TOPICATTACH%.


  • Before version 1.4 of this plugin, the extra TOPICCREATE parameters were passed in using a special parameters attribute, as follows:
       %TOPICCREATE{ template="MyTemplate" topic="%TOPIC%MyNewTopicName" parameters="MyParameterName=MyParameterValue&Hello=Goodbye" }%
    This is now depreciated. Instead, extra parameters are automatically passed through, as documented above.
  • The TOPICATTACH must be in the 'top level' topic being saved by a TOPICCREATE. It can not be in a recursive/subordinate topic invoked by the TOPICCREATE
  • There is a half-baked %TOPICPATCH% implementation which requires completing, testing and documenting. You are more than welcome to implement this if you would find it useful.

Plugin Settings

Plugin settings are stored as preferences values. You can override the defaults for these preferences in SitePreferences, the WebPreferences topic of the current web, or in individual topics that use the plugin. Changing them here will have no effect! This allows you to upgrade the plugin without having to worry about losing your settings.
