filter is not described

pre_site_option_(option) filter-hook . 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.


add_filter( 'pre_site_option_(option)', 'filter_function_name_2087', 10, 4 );
function filter_function_name_2087( $pre_option, $option, $network_id, $default ){
	// filter...

	return $pre_option;
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 name.
ID of the network.
The fallback value to return if the option does not exist.
Default: false
