Feature request: Purge page when custom post type is updated / added

[phwconz]

I often use custom post types and output them to a page. Would be great to be able to purge that page when a custom post is updated / added, i.e.: identical to the way the index page is purged when a new default post is created / updated.

Using the save_post_{$post_type} hook, which is fired whenever that custom post type is created or updated (see docs), you can add something like the following to your theme's functions.php file, or to a MU-Plugin, to clear the cache for a given page whenever a post with that custom post type is saved:

add_action( 'clear_cache_for_page_id_5', 'save_post_my-custom-post-type', 10, 1 );

function clear_cache_for_page_id_5( ) {
    $GLOBALS['quick_cache']->auto_purge_post_cache(5);
}

You'll want to change 5 to the ID of the Page/Post whose cache you'd like to clear when that custom post type is saved, and you'll want to change my-custom-post-type to the actual name of your Custom Post Type.

Awesome, thanks for the advice.
