Create new topics with simple forms like TWikiForms.


The RenderFormPlugin handles the variable %RENDERFORM{...}%. The variable will be replaced by a form that is defined and looks like TWikiForms. It helps you to create a new topic with TWikiForms or to edit or view existing topic form data. The form data can be changed without pushing the topic edit button. The variable can be used at any topic to show, edit or create TWikiForms data from any other topic.


  • easy to use: 1. define a form, 2. put the %RENDERFORM{...}% variable on a topic (you do not need to register a form or edit a page to add the form to a topic)
  • supports all form field types of TWikiForms (text, textarea, checkbox, checkbox+buttons , date, select, select+multi, radio, label)
  • supports 3 modes (mode option): create (default), edit, view (default if a topic exists)
  • mode switching: edit to view and view to edit
  • simple JavaScript based form field validator for mandatory fields
  • hide some form fields (hidden option)
  • change display order of form fields (order option)
  • use URL parameters to overwrite options (query parameter names: rfp_<attribute>)
  • define your own (mode dependent) form layout (layout option)

Syntax Rules

  • Usage: %RENDERFORM{attr1="val1" attr2="val2" ...}%
  • Example: %RENDERFORM{"TWikiFormDefinition"}% (=%RENDERFORM{form="TWikiFormDefinition"}%)

Quick Start Guide

  1. Create a new topic (e.g. TestForm?) for your TWikiForms definition and put the following to the new topic (ALERT! EditTablePlugin required):
    | *Name* | *Type* | *Size* | *Values* | *Tooltip message* | *Attributes* |
  2. Add some new rows to your TWikiForms definition by editing the definition table.
  3. Create a new topic (e.g. MyTestTopic?) and put the following to this new topic:
    %SEARCH{search="MyTestTopic\d+" scope="topic" type="regex"}%
  4. Have fun by creating new topics with forms (e.g. topic names: MyTestTopic0?, MyTestTopic1?, ...). smile

       -- a default layout --
    < your layout >
       -- OR a named layout --
    %STARTRENDERFORMLAYOUT{"< layout name >"}% 
    < your layout >

    %STARTRENDERFORMLAYOUT{"< layout name >" mode="view"}% 
    < your layout >
  • the layout names 'view', 'create' and 'edit' are reserved and should be used for mode specific layout definitions
  • if you use the mode option in %STARTRENDERFORMLAYOUT% this layout definition will be used only in the given mode (allowed modes: create,edit,view)
  • you can use form data values (view mode) or form fields (create/edit mode) by typing a tag like @< form field  name >@, e.g. @Question@
