_set_cron_array() WordPress Function

The set_cron_array() function is used to schedule events to be executed by the WordPress cron system. The function takes an array of cron event objects as its parameter. Each cron event object must contain a 'schedule' property, which defines when the event should be executed, and a 'hook' property, which is the name of the action hook that will be called when the event is executed.

_set_cron_array( array[] $cron, bool $wp_error = false ) #

function _set_cron_array( $cron, $wp_error = false ) {
	if ( ! is_array( $cron ) ) {
		$cron = array();
	}

	$cron['version'] = 2;
	$result          = update_option( 'cron', $cron );

	if ( $wp_error && ! $result ) {
		return new WP_Error(
			'could_not_set',
			__( 'The cron event list could not be saved.' )
		);
	}

	return $result;
