pre_unschedule_hook хук-фильтр . WP 5.1.0

Filter to preflight or hijack clearing all events attached to the hook.

Returning a non-null value will short-circuit the normal unscheduling process, causing the function to return the filtered value instead.

For plugins replacing wp-cron, return the number of events successfully unscheduled (zero if no events were registered with the hook) or false if unscheduling one or more events fails.


add_filter( 'pre_unschedule_hook', 'filter_function_name_6695', 10, 3 );
function filter_function_name_6695( $pre, $hook, $wp_error ){
	// filter...

	return $pre;
Value to return instead.
По умолчанию: null to continue unscheduling the hook
Action hook, the execution of which will be unscheduled.
Whether to return a WP_Error on failure.

Список изменений

С версии 5.1.0 Введена.
С версии 5.7.0 The $wp_error parameter was added, and a WP_Error object can now be returned.
