pre_clear_scheduled_hook
Filter HookDescription
Filter to override clearing a scheduled hook. 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 or a WP_Error if unscheduling one or more events fails.Hook Information
