pre_reschedule_event filter-hookWP 5.1.0

Filter to preflight or hijack rescheduling of a recurring event.

Returning a non-null value will short-circuit the normal rescheduling process, causing the function to return the filtered value instead.

For plugins replacing wp-cron, return true if the event was successfully rescheduled, false or a WP_Error if not.
