Is there a way to automatically flush permalinks in Word Press?

  Kiến thức lập trình

I need to save the permalinks on a site a few times daily, and want to know if it’s possible to have this done automatically.

The Word Press function to flush permalinks is flush_rewrite_rules(). Is it possible to get this function to run on its own on a timer? Once an hour?

I found this code here, but it does not work, and I do not understand how it would run 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;
