Hi,
I have multisite and I have created custom options by following this steps:
https://www.advancedcustomfields.com/add-ons/options-page/

So for ex now I have category as text fields exist for every site as an acf-options.

I want to get the sites by that custom acf-option.

I tried to run this query:

$sites = get_sites(
                array(
                'search' => get_search_query(),
		'search_columns' => array('path','domain','category') 
               )
            );

And I tried as well to write hook for site_search_columns to add the category column:

function custom_hook( $search_columns, $search ) {
    $search_columns[] = 'category';
    return $search_columns;	
}
add_filter( 'site_search_columns', 'custom_hook', 10, 3 );

But that’s dose really work, Any idea how to add the custom acf-options to site_search_columns ?

Thanks
