Removes a callback function from a filter hook.
This can be used to remove default functions attached to a specific filter hook and possibly replace them with a substitute. To remove a hook, the$callback
and $priority
arguments must match
when the hook was added. This goes for both filters and actions. No warning
will be given on removal failure.源码
function remove_filter( $hook_name, $callback, $priority = 10 ) { global $wp_filter; $r = false; if ( isset( $wp_filter[ $hook_name ] ) ) { $r = $wp_filter[ $hook_name ]->remove_filter( $hook_name, $callback, $priority ); if ( ! $wp_filter[ $hook_name ]->callbacks ) { unset( $wp_filter[ $hook_name ] ); } } return $r; }
