Create query_filter using multiple_domain value

Hi

Great plugin. I’m just trying to create a query filter, but can’t seem to get it to work. I want the meta_key, ‘author_email’ to match with the shortcode in meta_value.

I’ve used this guide to create the shortcode https://www.ads-software.com/support/topic/create-shortcode-based-on-multiple-domain-settings/

		function my_super_filter_function($query_args){
                     $query_args['meta_key'] = 'author_email';
                     $query_args['meta_value'] = <em>[multiple_domain_email]</em>;
                     return $query_args;
                }
               add_filter('my_super_filter', 'my_super_filter_function');

Thanks in advance ??
