How to use the WordPress Cron event list
1. Use plug-ins such as WP Crontrol or Advanced Cron Manager to view Cron events directly in the background; 2. You can also view cron key values by accessing the database wp_options table; 3. When debugging exceptions, you can disable WP-Cron and set system Cron tasks to improve reliability; 4. Manually running or deleting events can be achieved through plug-ins or adding code. It is recommended to give priority to using plug-in management. Users who are familiar with SQL can choose database operations, and pay attention to the trigger mechanism and the impact of visits during debugging.
If you want to know how to view and manage a list of Cron events in WordPress, there are actually several ways to do it. WordPress comes with a pseudo-timed task system called WP-Cron, which is not really timed execution like the server's Cron, but is enough for most plugins and themes.
However, by default WordPress does not provide an intuitive interface to let you see all Cron events directly. To view or manage these events, you need to use some tools or manual operations.
How to view the current list of WP-Cron events
The easiest way is to use plugins such as WP Crontrol or Advanced Cron Manager . Both plugins allow you to see all registered Cron events directly in the background, including their execution time, frequency, and corresponding hook functions.
If you don't want to install plugins, you can also view them through the database. The Cron event is stored in the wp_options table and the key name is cron . You can use phpMyAdmin or other database tools to find this entry, then decode its contents (usually serialized data), and you can see detailed event information.
- Using plug-ins is the most convenient way
- The database method is suitable for users who are familiar with SQL
- It is recommended to back up the data before viewing to avoid misoperation
How to debug WP-Cron execution exception problem
Sometimes you will find that a timing task is not running as expected. At this time, you must first confirm whether your website has been accessed and triggered WP-Cron. Because the default WP-Cron depends on page access, if the website visits are low, Cron will not be executed in time.
You can disable the default WP-Cron in wp-config.php and use the system's Cron to call it instead:
define('DISABLE_WP_CRON', true);
Then add a real Cron task on the server, such as once a minute:
*/1 * * * * curl https://your-site.com/wp-cron.php
This allows timed tasks to run more reliably.
How to manually run or delete a Cron event
Sometimes you want to test whether a timing task works properly or you want to clean up tasks that you no longer need. Using a plugin like WP Crontrol , it is easy to run an event manually or delete it directly from the list.
If you choose not to use plugins, you can also operate through code. For example, add the following code to the theme's functions.php file to manually trigger a hook:
wp_schedule_single_event( time(), 'your_custom_hook_name' );
Or delete an event:
wp_unschedule_event( $timestamp, 'your_custom_hook_name' );
Remember to delete the code after the operation is completed, otherwise it may be executed repeatedly.
Basically that's it. Although viewing and managing WP-Cron events is not particularly complicated, it is indeed easy to ignore details, especially when debugging. As long as you master the basic methods, it is not difficult to deal with most problems.
