FYI function should look like this:

// bail early if is in admin
if( is_admin() ) {
return;
}

// bail early if not main query
// – allows custom code / plugins to continue working
if( !$query->is_main_query() ) return;

// get meta query
$meta_query = $query->get(‘meta_query’);

$meta_query = array(
‘relation’ => ‘AND’,
);
foreach ($GLOBALS[‘my_query_filters’] as $key => $name) {

if (!empty($_GET[$name])) {

$values = explode(‘,’, $_GET[$name]);

$meta_query[] = array (
‘key’ => $name,
‘value’ => $values,
‘compare’ => ‘IN’,
);

}
}

$query->set(‘meta_query’, $meta_query);

return;
