Filter to preflight or hijack clearing a scheduled hook.

Syntax Syntax

apply_filters( 'pre_clear_scheduled_hook', null|int|false $pre, 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 the number of events successfully unscheduled (zero if no events were registered with the hook) or false if unscheduling one or more events fails.

Parameters Parameters


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


Action hook, the execution of which will be unscheduled.


Arguments to pass to the hook's callback function.
