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.

$pre_option 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 false (to skip past the short-circuit).

$option string

Option name.

$network_id int

ID of the network.

$default mixed

The fallback value to return if the option does not exist.
Default false.
