Automatically sets VIEW_TEMPLATE and EDIT_TEMPLATE


This plugin sets the VIEW_TEMPLATE and EDIT_TEMPLATE variables according to a corresponding form definition. So when you attach a new form to a topic, this plugin will enable the corresponding view/edit template automatically. This comes in very handy for applications where users create new topics without the help of a topic creator wizard, e.g. creating a new topic for a yet non-existing WikiWord. Together with the appropriate application settings, this plugin will then assure that the data the user enters is handled appropriately during view and edit.

There are two modes on how the name of the template is derived:

  1. exist (default) and
  2. section.

Mode "exist"

A topic that has a MyForm TWikiForm attached to it, will be displayed using the view template MyView and editted using the MyEdit if they exist. The template name is derived by stripping off the suffix ...Form from the form name and appending ...View. The TWiki engine will then use the template name MyView to search for the correct template along the template search path, for example using a topic MyView.


You have a form called PurchaseRequestForm. The plugin will now search for PurchaseRequestViewTemplate, and PurchaseRequestEditTemplate.

Mode "section"

A topic with a MyForm will be displayed/editted using the template name stored in the named section viewtemplate/edittemplate . For example given the MyForm form definition topic contains a section viewtemplate whose only content is MyOtherView, then this will be used to view the topic. Likewise, the content of the edittemplate section in MyForm will read to find the edit template.

By default existing values for VIEW_TEMPLATE and EDIT_TEMPLATE have priority. You can change this behaviour in configure so that the form defined templates have priority.


We have a form called PurchaseRequestForm which contains the usual table that defined the form fields.

We want this form to define that the topics are viewed with ViewFormAtTopTemplate and edited with EditPurchaseRequestTemplate.

Below this we place the two sections that defines the templates to be used. Note that you must ommit the ...Template from the template names.
