Viewing Meta Data in Page Source |
|
<
< | When viewing a topic the Raw Text link can be clicked to show the text of a topic (i.e., as seen when editing). This is done by adding raw=on to URL. raw=debug shows the meta data as well as the topic data, ex: debug view for this topic |

Rendering Meta Data
Meta Data is rendered with the %META% variable. This is mostly used in the view, preview and edit scripts. |
|
<
< | Note: Rendering meta data is currently not supported in topic text. As a workaround, use FormattedSearch on the current topic only to render form fields. |
>
> | You can render form fields in topic text by using the FORMFIELD variable. Example:
%FORMFIELD{"TopicClassification"}%
For details, see TWikiVariables#VarFORMFIELD. |
