Filter to preflight or hijack unscheduling of events.

Syntax Syntax

apply_filters( 'pre_unschedule_event', null|bool $pre, int $timestamp, string $hook, array $args )

Description 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 true if the event was successfully unscheduled, false if not.

Parameters Parameters


Value to return instead. Default null to continue unscheduling the event.


Timestamp for when to run the event.


Action hook, the execution of which will be unscheduled.


Arguments to pass to the hook's callback function.
