pre_clear_scheduled_hook ›

apply_filters( 'pre_clear_scheduled_hook', null, $hook, $args )
Parameter: (3)
  • (null|int|false) $pre Value to return instead. Default null to continue unscheduling the event.
    Erforderlich: Ja
  • (string) $hook Action hook, the execution of which will be unscheduled.
    Erforderlich: Ja
  • (array) $args Arguments to pass to the hook's callback function.
    Erforderlich: Ja
Definiert in:

Filter to preflight or hijack clearing a scheduled hook.

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.
