Extended functions and parameters

Extenders are sets of extra parameters, functions, placeholders and filters that extend Ditto's functionality. Several extenders are installed by default with Ditto 2.1, including

• Summary - generate content for [+summary+] placeholder in blogs etc.
• Tagging - support for tags in blog posts, categories etc.
• Request - set Ditto parameters via URL (see also config files)
• DateFilter - filter by date in specified field

With sufficient knowledge of PHP and the inner workings of Ditto, and a good supply of wet towels to cool the brain, it is possible to create your own extender using the example file that is supplied with Ditto.

The &extenders parameter adds one or more extenders (names separated by commas) to your Ditto call. The tagging extender is added automatically when you use the &tagData parameter in a Ditto call.

Here's a Ditto call covering a set of documents that can have one or more of three tags (set by a checkbox template variable). Links to individual items and tagged sets of items are simple to create using the placeholders. (View template)
