i'm trying to debug a plugin which i didn't create and i want to list all registered actions. i read this http://stackoverflow.com/questions/5224209/wordpress-how-do-i-get-all-the-registered-functions-for-the-content-filter but it's specific to one hook and it's about filters, not actions. Is there any variable like $wp_filter or something?

Filters and actions are both assigned to hooks. Functions assigned to hooks are stored in global $wp_filter variable. So all you have to do is to print_r it.

global $wp_filter;
print_r($wp_filter);

PS. add_action function makes a add_filter call. And the latter does $wp_filter[$tag][$priority][$idx].

my bad, shouldn't write global $wp_filter; –  Jacer Omri Jul 2 '13 at 15:03
    
OK, so you worked that out? –  Krzysiek Dróżdż Jul 2 '13 at 15:12
