Is there a quick way to view the wp-cron schedule

Question

I'm trying to work which plugin is triggering wp-cron. I know about the code: http://codex.wordpress.org/Function_Reference/wp_get_schedules , but I'd prefer to do something in the sql backend rather than write a plugin.

Answer 1

Why don't you just create a cron job, make a database dump and look where the info about the cron job is kept? That's what I did. As suspected, WordPress 3.5.1 keeps its cron jobs in the {wp}_options table under the name 'cron'.

SELECT *
FROM `wp_options`
WHERE `option_name` LIKE '%cron%'

Or through functions.php:

$cron_jobs = get_option( 'cron' );
var_dump($cron_jobs);

Answer 2

You can use the WP-CLI.

From the command line, you can run the following command from the directory of your WordPress installation:

wp cron event list  

It will display a table of the scheduled events, when it's set to run, and how often it's rescheduled. Here is what was returned to me when I ran the command:

Answer 3

WordPress has an undocumented function, _get_cron_array(), that returns an array of all currently scheduled tasks. We are going to use a crude but effective method to dump out all the tasks using var_dump(). For ease of use place the following code in the plugin:

echo '<pre>';
print_r( _get_cron_array() );
echo '</pre>';
