=== Plugin Dependencies === Contributors: scribu Tags: plugin, dependency Requires at least: 3.1 Tested up to: 3.3 Stable tag: 1.2 License: GPLv2 or later License URI: http://www.gnu.org/licenses/gpl-2.0.html Plugin dependency management == Description == This meta-plugin allows regular plugins to specify other plugins that they depend upon. Example: ` /* Plugin Name: BuddyPress Debug Depends: BuddyPress, Debug Bar */ ` What this does: * Disables activation of *BuddyPress Debug* until both *BuddyPress* and *Debug Bar* are already activated. * When either *BuddyPress* or *Debug Bar* are deactivated, *BuddyPress Debug* will also be deactivated. Links: [Plugin News](http://scribu.net/wordpress/plugin-dependencies) | [Author's Site](http://scribu.net) == Frequently Asked Questions == = Error on activation: "Parse error: syntax error, unexpected..." = Make sure your host is running PHP 5. The only foolproof way to do this is to add this line to wp-config.php (after the opening `<?php` tag): `var_dump(PHP_VERSION);` <br> = What happens if a user doesn't have Plugin Dependencies installed? = Nothing. The *Depends:* header will simply be ignored. = Can I have grand-child plugins? = Yes, the dependency chain can go as deep as you want. = Defining virtual packages = Say you have some useful functions that you would like to package up as a library plugin: ` /* Plugin Name: Facebook Lib Provides: lib-facebook */ ` Now, dependant plugins can specify 'lib-facebook' as a dependency: ` /* Plugin Name: Cool Facebook Plugin Depends: lib-facebook */ ` Besides being more robust, the *Provides:* header allows multiple plugins to implement the same set of functionality and be used interchangeably. == Screenshots == 1. Activation prevention 2. Cascade deactivation == Changelog == = 1.2 = * added ability to use plugin names as dependencies * [more info](http://scribu.net/wordpress/plugin-dependencies/pd-1-2.html) = 1.1 = * added 'Provides:' header * replaced 'Dependencies:' with 'Depends:' * [more info](http://scribu.net/wordpress/plugin-dependencies/pd-1-1.html) = 1.0.1 = * fixed critical bug when not running MultiSite * better network activation handling = 1.0 = * initial release * [more info](http://scribu.net/wordpress/plugin-dependencies/pd-1-0.html)
