Extension:Widgets

Widgets extension allows adding widgets to wiki by just creating pages in Widget namespace.

This extension was developed by Sergey Chernyshev for Ardorado.com and sponsored by Semantic Communities, LLC.

Usage
To add a widget to MediaWiki installation, just create a page in Widget namespace and then use  parser function to include it to the pages of the wiki.

parser function
To add defined widget to pages, users can use  parser function. The syntax is as follows:

Where WidgetName is a page name in Widget namespace (e.g. Widget:WidgetName) and param=value pairs are defining parameters defined within widget code.

Widget page syntax
Widget extension uses Smarty PHP templating engine to provide simple templating functionality within widget pages. All parameters passed to widget are converted into Smarty parameters.

You should use escape modifiers to make sure that user parameters can not expose hosting website to XSS (or any other) attacks.
