Methods

hasAction()

hasAction(string  $hook, callable|boolean  $function_to_check = false) : boolean|integer

Check if any action has been registered for a hook.

Parameters

string $hook

The name of the action hook.

callable|boolean $function_to_check

Optional. The callback to check for. Default false.

Returns

boolean|integer —

If $function_to_check is omitted, returns boolean for whether the hook has anything registered. When checking a specific function/method, the priority of that hook is returned, or false if the function/method is not attached. When using the $function_to_check argument, this function/method may return a non-boolean value that evaluates to false (e.g.) 0, so use the === operator for testing the return value.
