Cos’è il Cron di WordPress?

The cron is a term derived from the Unix/Linux world that refers to a automatic activity planning service. In WordPress, the cron serves to programming e manage azioni ricorrenti o pianificate, come la pubblicazione di post, l’invio di email, la pulizia della cache e molto altro.

In practice, WordPress uses a system of pseudo-cron called WP-Cron. Unlike the traditional cron, which executes tasks at set times, WP-Cron is activated every time someone visits the site. This means that planned activities will not be executed until the site receives a visit. This approach has its pros and cons, which we will examine later.

How Does WP-Cron Work?

When a user visits your site, WordPress checks whether there are any scheduled tasks to be performed. If yes, these are executed immediately. This system is very useful for small websites o blog with limited traffic, where there is no need to perform cron actions at specific times.

Here is how the process works:

  1. Trigger: Each time a user visits the site, WP-Cron is activated.
  2. Control of activities: WP-Cron checks whether there are any planned events.
  3. Execution: If there are scheduled tasks, WP-Cron executes them immediately.

For example, if you have scheduled a post to be published at 10:00, but no one visits the site until 10:30, the post will only be published at 10:30.

Limitations and Problems of WP-Cron

Although WP-Cron is a very useful tool, it has some limits e problems worth considering:

  1. Dependence on traffic: If your site has little traffic, cron activities may not be performed in a timely manner.
  2. Server load: WP-Cron is executed every time a user visits the site, which can increase the load on the server if you have a site with a lot of traffic.
  3. Unreliability: In some cases, WP-Cron may not function properly, especially on shared hosting with limited resources.

How to Optimise WP-Cron

Se gestisci un sito con un traffico significativo o hai bisogno di un’esecuzione più affidabile delle attività cron, potresti voler disable WP-Cron and set up a true cron job at server level. This approach is more reliable and allows scheduled tasks to be executed at specific times, regardless of site traffic.

Here are the steps to optimise WP-Cron:

  1. Disable WP-Cron: You can do this by adding the following line to the wp-config.php of your site:
    define(DISABLE_WP_CRON', true);
  2. Create a cron job at server level: Depending on your hosting, you can access the control panel and set up a cron job that executes the script wp-cron.php every 15 minutes or at a time interval of your choice.
