| | Overview
By adding form-based input to free-form content, you can structure topics with unlimited, easily searchable categories. When forms are enabled for a web and selected in a topic, the form appears in edit mode, and the contents are rendered as a table when viewing the actual page. When editing, can switch forms, if more than one is defined, or remove forms entirely. Form input values are stored as TWikiMetaData; all data is saved. |

Changes from the Category Table System
Form Templates more powerful, flexible replacement for the original TWikiCategoryTable. Data from existing category tables can be imported directly.
Main changes from TWikiCategoryTable:
| Form Templates | Category Tables |
|---|
| defined in topics | defined in templates |
| many forms per web | one table per web |
| saved as Meta Data | saved as HTML |
| Change & Add Form buttons | UseCategory radio button |
Importing Existing Category Table Data
On upgrading from the previous TWiki, a Form Template topic has to be built for each web that used a Category Table, recreating the fields and values from the old twikicatitems.tmpl. The replacement Form Template must be set as the first item in the WebPreferences variable =WEBFORM. If missing, pages will display, but attempting to edit results in an error message.
The new Form Template system should work with old Category Table data with no special conversion. Data is assigned to Meta variables the first time an imported topic is edited and saved in the new system.
NOTE: If things aren't working correctly, there may be useful entries in data/warning.txt. |
