Tell us what you are trying to do?

Is it possible to set in view or wordpress archive view a filter that filters out posts from loop that do not have featured image?

Hello,

It is possible with custom codes, you can try the views filter hook wpv_filter_query, for example, for a normal post view( ID 123), you can add below codes into your theme file functions.php:

add_filter( 'wpv_filter_query', 'add_filter_by_thumbnail', 10, 3 );
function add_filter_by_thumbnail ( $query, $view_settings, $view_id ) {
  if( $view_id == 123) {
    $args = array(
      'relation' => 'AND',
      array(
        'key' => '_thumbnail_id',
        'compare' => 'NOT EXISTS'
      )
    );
    // add these arguments to your meta query
    $query['meta_query'] = isset($query['meta_query']) ? $query['meta_query'] : [];
    $query['meta_query'][] = $args;
  }
  return $query;
}

Please replace 123 with your view's ID

Hi, thanks for the code!

I've added these lines in functions.php and replaced ID with my wordpress archive view id.

Still, it's displaying posts without featured image. Here is a link: hidden link

Hmm, still nothing has changed.

I'm sending functions.php SC in attachment

I assume we are talking about the "apartment" term's archive page

For the WordPress archive, you will need to try WordPress built-in filter hook "pre_get_posts", for example, you can change the PHP codes as below:

add_action( 'pre_get_posts', 'add_filter_by_thumbnail', 99);
function add_filter_by_thumbnail ( $query ) {
  if( ! is_admin() && $query->is_main_query() && is_tax('property-type', 'apartment') ) {
    $args = array(
      'relation' => 'AND',
      array(
        'key' => '_thumbnail_id',
        'compare' => 'EXISTS'
      )
    );
	$meta_query = (array)$query->get('meta_query');
    $meta_query[] = $args;
	$query->set( 'meta_query', $meta_query );
  }
  return $query;
}

Nice! It works 😀

Is it possible to apply this code to all "property-type" archives? or I need to add this code for each property type category?

For istance, other than apartment I have hotels, rooms, camping, etc. And also translation of them.

You can change this code from:
is_tax('property-type', 'apartment')

To:
is_tax('property-type')
