apply_filters( "pre_site_option_{$option}", mixed $pre_option, string $option, int $network_id, mixed $default )

Filters an existing network option before it is retrieved.


The dynamic portion of the hook name, $option, refers to the option name.

Passing a truthy value to the filter will effectively short-circuit retrieval, returning the passed value instead.



(mixed) The value to return instead of the option value. This differs from $default, which is used as the fallback value in the event the option doesn't exist elsewhere in get_network_option(). Default is false (to skip past the short-circuit).


(string) Option name.


(int) ID of the network.


(mixed) The fallback value to return if the option does not exist. Default is false.
