pre_unschedule_event │ filter-hook │ WP 5.1.0

Filter to override unscheduling of events.

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 true if the event was successfully unscheduled, false or a WP_Error if not.

Usage

add_filter( 'pre_unschedule_event', 'wp_kama_pre_unschedule_event_filter', 10, 5 );
