Hi, I’m try to query post only if in a post object field there is an ID.
I’ve tried with this and similar query but not work.

$query_args = array(
     'post_type'      => 'post_type',
     'posts_per_page' => 10,
     'orderby'	      => 'title',
     'order'	      => 'ASC',
     'paged'          => $paged
);
                                            
if(isset($nome) && $nome) { 
$query_args['meta_query'][] = array('key' => 'nome', 'value' => $nome, 'compare' => 'LIKE'); }
                                            
if(isset($ref) && $ref) {
$query_args['meta_query'][] = array('key' => 'collegamento', 'value' => '"' . $ref . '"', 'compare' => 'LIKE'); }

I think is possible but I can not find the right code.

Thanks for help!
