如何在wordpress中编写真正的cron作业？

Question

I have done define('DISABLE_WP_CRON', 'true'); in wp-config.php.

I set up the cron path but I actually do not know how to write code so that calling that URL will execute my code. I want to write real cron job over WordPress cron job.

I tried with this in function.php but it did not work:

if (! wp_next_scheduled ( 'my_hourly_event' )) {
    wp_schedule_event(time(), 'hourly', 'my_hourly_event');
    }
add_action('my_hourly_event', 'do_this_hourly');

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

Here is a link to the post that solve it for me: http://support.hostgator.com/articles/how-to-replace-wordpress-cron-with-a-real-cron-job

Takeaways:

• You seem to have prepared everything correctly - your code schedules the execution of do_this_hourly function every hour. However, due to define('DISABLE_WP_CRON', 'true'); in wp-config.php the function is only scheduled and never executed unless you make a request to http://yourwebsite.com/wp-cron.php?doing_wp_cron yourself.
• The only thing left to do is to setup system cron
• If you are on Unix-based system (Linux/Mac), then try crontab -e from the command line on your server, and add a line like this: wget -q -O - http://yourwebsite.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1

Don't forget to replace http://yourwebsite.com with whatever your website domain is.

Good luck!
