wp_unschedule_event() WP 1.0

Unschedule a previously scheduled event.

The $timestamp and $hook parameters are required so that the event can be identified.

Возвращает

true/false. True if event successfully unscheduled. False for failure.

Usage

wp_unschedule_event( $timestamp, $hook, $args );

$timestamp(int) (required)

Unix timestamp (UTC) of the event.

$hook(string) (required)

Action hook of the event.

$args(array)

Array containing each separate argument to pass to the hook's callback function. Although not passed to a callback, these arguments are used to uniquely identify the event, so they should be the same as those used when originally scheduling the event.
Default: array()

	 * @param string    $hook      Action hook, the execution of which will be unscheduled.
	 * @param array     $args      Arguments to pass to the hook's callback function.
