pre_clear_scheduled_hook WordPress Filter Hook
The pre_clear_scheduled_hook hook is called before a scheduled event is cleared from the database. This hook can be used to perform any necessary actions before an event is deleted, such as cleaning up any associated data.
apply_filters( 'pre_clear_scheduled_hook', null|int|false|WP_Error $pre , string $hook , array $args , bool $wp_error ) #
Filter to preflight or hijack clearing a scheduled hook.
Description
Returning a non-null value will short-circuit the normal unscheduling process, causing the function to return the filtered value instead.
For plugins replacing wp-cron, return the number of events successfully unscheduled (zero if no events were registered with the hook) or false if unscheduling one or more events fails.
