[edit] Description
Fast and simple extension, that lists pages included in several specified categories at once. By default, user can specify up to 5 such categories, and optionally up to 3 categories to exclude from search. The maximum number of categories is set in two corresponding variables in source code, so you can easily change it at any time. On many requests, drop-down lists support was added in version 1.3.
[edit] Purpose and usage
The extension is indispensable if you need, for example, to find all articles about american comedy movies released in 1990 on your cinema-related wiki. Then you go to page [[Special:MultiCategorySearch]], specify three categories: "USA films", "Comedy films" and "1990 films", and click on search button. That's it - you get the list of movies.
[edit] Installation
- Download the extension code.
- Unzip and save the code files in your wiki's
extensionsdirectory in aMultiCategorySearchsubdirectory. - Changes your wiki's LocalSettings.php file to include the line:
require_once("$IP/extensions/MultiCategorySearch/MultiCategorySearch.php");
[edit] Configuration
General configuration settings are set in variables in the beginning of MultiCategorySearch_body.php file. Here are sample settings and their description.
Maximum number of categories, that user can search for:
var $inCategoriesNumber = 5;
Maximum number of categories, that user can exclude from search:
var $exCategoriesNumber = 3;
Default method of HTTP parameters passing. Change to 'get', if you need it.
var $paramsPassMethod = 'post';
When set to true, inserts MediaWiki:Edittools at the bottom of search form. But remember, that EditTools require Extension:CharInsert to be installed and AJAX to be enabled (global $wgUseAjax variable must be set to true in LocalSettings.php file).
var $insertEditTools = false;
When set to true, allows to use custom drop-down lists for categories selection. Options for drop-down lists must be manually set in the body of showDropdownLists() function in the end of MultiCategorySearch_body.php script.
var $useDropdownLists = false;
[edit] Transclusion
By transclusion the multi-category search results could be dynamically shown on some other page. Transclusion format is: {{Special:MultiCategorySearch/include=Category 1/include=Category 2/exclude=Category 3}}
[edit] Database compatibility note
Extension won't work on some very old database engines, that don't support SQL subqueries. In that case, please, upgrade your database engine.
