apply_filters( 'pre_clear_scheduled_hook', null|int|false $pre, string $hook, array $args )

Filter to preflight or hijack clearing a scheduled hook.

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

$pre

(null|int|false) Value to return instead. Default null to continue unscheduling the event.

$hook

(string) Action hook, the execution of which will be unscheduled.

$args

(array) Arguments to pass to the hook's callback function.
