How to Flush Permalinks Once Per Hour Cron Job

Are you looking for a way to flush the permalinks once in every hour? While there’s probably a plugin for this, we have created a quick code snippet that you can use to flush permalinks once per hour cron job in WordPress.

To confirm permalinks are being flushed, simply add a comment just before # END WordPress in the .htaccess file. Once permalinks are flushed, the comment will disappear.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

// Flush permalinks every hour 
add_action('my_hourly_event', 'do_this_hourly');

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

add_action('wp', 'my_activation');

function do_this_hourly() {
	global $wp_rewrite;
	$wp_rewrite->flush_rules();
}
