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 value other than false from the filter will short-circuit retrieval and return that value instead.

Usage

add_filter( 'pre_site_option_(option)', 'wp_kama_pre_site_option_filter', 10, 4 );
