I created a custom taxonomy and some post meta values, stored in the database. They are used for a taxonomy filter I am working on. The values are related to a custom post type (advertisement). When the user selects the filter option(s), a form is submitted (method is post, no ajax). I’m fetching the post variables in the filter via a function call.
As said, your suggestion works fine and with the filter I can achieve what I want, but I have the feeling that it’s a makeshift solution I’ve created😉.

Hello Tom,
Based on your suggestions, I’ve created a filter (see below, sorry for the lengty code here), and it works fine! Still some additions to make, though. E.g. I don’t like the way I’m passing variables right now. Via a function inside the filter I collect some $_POST data, but I can’t find onother a way to pass variables to the filter. As far as I know that’s not possible, or am I overlooking something? I’m a bit reluctant to pass global variables.
// Filter query arguments for WP Show Posts add_filter( 'wpsp_query_args', function( $args, $settings ) { // Declare variables $bd_location_key = $bd_location_value = ''; $bd_filter_data = []; // Get location data ( passed via $_POST and already sanitized/escaped ) $bd_filter_data = bd_get_location_post(); // Assign location data to variables // Because not all location data have to be passed, // we start at the top level (country), down to the most detailled level (city) // Descending order: Country -> State -> County - City [ ... in my script, here are the conditionals tot assign value to $bd_location_key and $bd_location_value. I've skipped them here ... ] // Add query arguments to WP Show Posts // Also create a custom order clause, so we can filter on // the avarage rating, stored in post meta if ( 97 === (int) $settings[ 'list_id' ] ) { $args[ 'meta_query' ] = array( array( 'key' => $bd_location_key, 'value' => array_shift( $bd_location_value ), 'compare' => 'LIKE', 'orderby' => 'meta_value', 'order' => 'ASC', ), 'bd_rating_order_clause' => array( 'key' => 'bd_post_average_rating' ), ); $args[ 'orderby' ] = array( 'bd_rating_order_clause' => 'DESC' ); } return $args; }, 10, 2 );I have added an extra argument to the filter and changed the number of arguments to 3, but that throws an error.
