apply_filters( 'pre_unschedule_hook', null|int|false|WP_Error $pre, string $hook, bool $wp_error )

Filter to preflight or hijack clearing all events attached to the 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

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

$hook

Action hook, the execution of which will be unscheduled.

$wp_error

Whether to return a WP_Error on failure.
