wp_clear_scheduled_hook() WP 1.0

Unschedules all events attached to the hook with the specified arguments.

Works based on: wp_unschedule_event()

No Hooks.


Nothing (null).


wp_clear_scheduled_hook( $hook, $args );
$hook(string) (required)
Action hook, the execution of which will be unscheduled.
Arguments that were to be passed to the hook's callback function.
Default: array()

Code of wp clear scheduled hook: wp-includes/cron.php VER 5.0.3

function wp_clear_scheduled_hook( $hook, $args = array() ) {
	// Backward compatibility
	// Previously this function took the arguments as discrete vars rather than an array like the rest of the API
	if ( !is_array($args) ) {
		_deprecated_argument( __FUNCTION__, '3.0.0', __('This argument has changed to an array to match the behavior of the other cron functions.') );
		$args = array_slice( func_get_args(), 1 );

	// This logic duplicates wp_next_scheduled()
	// It's required due to a scenario where wp_unschedule_event() fails due to update_option() failing,
	// and, wp_next_scheduled() returns the same schedule in an infinite loop.
	$crons = _get_cron_array();
	if ( empty( $crons ) )

	$key = md5( serialize( $args ) );
	foreach ( $crons as $timestamp => $cron ) {
		if ( isset( $cron[ $hook ][ $key ] ) ) {
			wp_unschedule_event( $timestamp, $hook, $args );
