Examples

Schedule an hourly event

To schedule an hourly event in a plugin, call wp_schedule_event on activation (otherwise you will end up with a lot of scheduled events!):

register_activation_hook(__FILE__, 'my_activation');
add_action('my_hourly_event', 'do_this_hourly');

function my_activation() {
	wp_schedule_event(time(), 'hourly', 'my_hourly_event');
}

function do_this_hourly() {
	// do something every hour
}
