pre_site_option_(option) хук-фильтр . WP 3.0.0

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 truthy value from the filter will effectively short-circuit retrieval and return the passed value instead.
