MediaCategories

Question

I want a painless way of implementing the Mediawiki markup for categories.

Answer

Media Categories simulates the style of the Mediawiki wiki markup. When categories are listed on a line it will label them and put them into a block.

Notes

To use this script, simply copy it into the cookbook/ directory and add the following line to config.php (or a per-page/per-groupcustomization file).

 include_once("$FarmD/cookbook/mediacat.php");

Throughout the document, you can place the categories, for example [[!ChickenRecipes]] and [[!Frog Recipes]]. These are pulled from the page, alphabetized, then added at the end of the page. This recipe allows you to set the singular/plural of the category list that is then appended to the end of the page like thus:

The categories are also encapsulated in a div statement (named "category") that allows the site administrator to customize the style for this block.

Install.

1. Download the mediacat.phpΔ file, and put in your cookbook directory.
2. Add this line to the appropriate config.php file include_once("$FarmD/cookbook/cookbook/mediacat.php");. It is better to put this line after any redesignation of $CategoryGroup. This variable is used establish the correct link.
3. Use it.

New in Version 2.2.4

The $McatShowCategoryLinksAsTitles has been added (can be set in config.php). If this option is set to true, then category links in the category block will display as the title of the category page (which may be set, on each Category/Whatever page, in the usual way, via the (:title:) directive). Defaults to false (i.e. the default behavior is the same as before—category links will display just as they appear on the page).

New in Version 2.2

Links of the form [[!MyCoolCategory]] (with an exclamation point) now also work, in addition to links of the form [[Category:MyCoolCategory]].

New in Version 2.1

Updated to play well with PmWiki's new built-in category functionality. This recipe now collects only links of the form [[Category:MyCoolCategory]] (a la MediaWiki), and places them in the div.category block at bottom.

New in Version 2.0

My friend Mateusz brought up some good points in a list of notes. In the spirit of friendly competition, I chose to respond by making a better product. Granted, it took me a few months to notice the comments. BenWilson May 07, 2006, at 04:44 PM

• MediaCategories now pulls free links? using the PmWiki syntax [[!Category Name]], even with spaces.
• Categories can appear anywhere in the page. After being inventoried, these categories are appended to the end of the page.
• This version does not rely on spaces, which presented a serious problem in v1.0

Customizable Variables:

$McatLabelS

This sets the singular form of the category label. Defaults to "Category:"

$McatLabelP

This sets the plural form of the category label. Defaults to "Categories:"

$McatSep

This determines what the seperator format is. Defaults to ' | '

$McatBlockStart

This creates the markup that creats the block.

$McatBlockEnd

This creates the markup that terminates the block.

$McatCSSStyle

This is the CSS that is added to $HTMLStylesFmt when categories are marked up by this script.

$McatShowCategoryLinksAsTitles

If this option is set to true, then category links in the category block will display as the title of the category page. Defaults to false.

$McatShowCategoriesOnIncludedPages

If this option is set to true, then category links from included pages are shown on the currently displayed page. Defaults to false. (Note that this does not cause the current page to be added to those categories.)
