WP hooks navigation: Home/browse • Actions index • Filters index
To save our bandwidth, we show only a snippet of code around each occurence of the hook. View complete file in SVN (without highlighting).
The best way to understand what a hook does is to look at where it occurs in the source code.
do_action( "hook_name" )apply_filters( "hook_name", "what_to_filter" ).Remember, this hook may occur in more than one file. Moreover, the hook's context may change from version to version.

| 203 | The following filter takes an associative array of external plugins for TinyMCE in the form 'plugin_name' => 'url'. |
| 204 | It adds the plugin's name to TinyMCE's plugins init and the call to PluginManager to load the plugin. |
| 205 | The url should be absolute and should include the js file name to be loaded. Example: |
| 206 | array( 'myplugin' => 'http://my-site.com/wp-content/plugins/myfolder/mce_plugin.js' ) |
