Delete all scheduled events with a particular hook

Question

I have several cron jobs all hooked to the same hook, but each with a different argument (a post ID). It appears wp_clear_scheduled_hook only clears job which match the argument passed with it (or jobs without any arguments, if no argument is provided).

Is there a way to delete all the cron jobs associated with a hook, regardless of the argument that job has? (Without doing so 'manually' by looping through the IDs).

Seems an answer was deleted! To clarify what I would like to achieve: each post has an expiration date - and I would like to delete the post after this date.

(An alternative option is to have one cron job - repeating every 24 hours that deletes any expired posts).

However, I decided to create a one-off job for each post - but it seems you can't delete all the jobs at once without cycling through them.

Answer 1

4.9.0 introduced wp_unschedule_hook()

Answer 2

I have just quickly wrote the below function, it will clear all crons for the specified hook, irrespective of the cron time and the hook argument.

NOTE: I have NOT TESTED the function, so please don't run it on your live site.

function wpse39681_clear_all_crons( $hook ) {
    $crons = _get_cron_array();
    if ( empty( $crons ) ) {
        return;
    }
    foreach( $crons as $timestamp => $cron ) {
        if ( ! empty( $cron[$hook] ) )  {
            unset( $crons[$timestamp][$hook] );
        }

        if ( empty( $crons[$timestamp] ) ) {
            unset( $crons[$timestamp] );
        }
    }
    _set_cron_array( $crons );
}
