TIP RenderFormPlugin is not installed on Foswiki.org.


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

  • easy to use: 1. define a form, 2. put the %RENDERFORM{...}% tag 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 DataForms (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 override 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{"DataFormDefinition"}% (=%RENDERFORM{form="DataFormDefinition"}%)

Quick Start Guide

  1. Create a new topic (e.g. TestForm) for your DataForms 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 DataForms 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

Form Layout

Usage: %RENDERFORM{"<form definition>" ... layout="<layout topic>"}%
-or- %RENDERFORM{"<form definition>" ... layout="<layout topic>#<layout name>"}%

  • a form layout is surrounded with the tags %STARTRENDERFORMLAYOUT% and %STOPRENDERFORMLAYOUT%, e.g:
       -- a default layout --
    < your layout >
       -- OR a named layout --
    %STARTRENDERFORMLAYOUT{"< layout name >"}% 
    < your layout >
       -- OR a named layout for view mode --
    %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@

Following tags are reserved and replaced by ...
Tag Replaced by
@FORMTOPIC@ the form topic name
@OPTION(<attribute name>)@ the attribute value, e.g. @OPTION(mode)@
@SUBMIT@ a submit button or empty string in view mode (hint: change the button text with the createbutton or editbutton attributes)
@SWITCH@ a link to switch between edit and view mode
@TOPIC@ the (target) topic name of the topic with a form

  • The default field marker '@' can be changed with the fieldmarker attribute.
  • Put the complete layout definition between <verbatim>...</verbatim> tags to make the definition visible in the topic view.

Form Layout Example:
|  *@TOPIC@@SWITCH@ / @FORM@*||
|  Question%RED%*%ENDCOLOR% | @Question@ |
|  Details | @Details@ |
|  %RED%*%ENDCOLOR% indicates mandatory fields||
