Opis — z kodu źródłowego

Filters the value of an existing network option before it is retrieved.

The dynamic portion of the hook name, $option, refers to the option name. Returning a value other than false from the filter will short-circuit retrieval and return that value instead.

Parametry

Parametr	Typ	Opis
`$pre_site_option`	mixed	The value to return instead of the option value. This differs from <code>$default_value</code>, which is used as the fallback value in the event the option doesn't exist elsewhere in get_network_option(). Default false (to skip past the short-circuit).
`$option`	string	Option name.
`$network_id`	int	ID of the network.
`$default_value`	mixed	The fallback value to return if the option does not exist. Default false.
