I have a custom taxonomy lets call it "indications". We use it with a custom post type "Product". We use a hierarchy for the terms Parent->Child. The Parent has never an connection with a product. I use it to make a custom select field and would need the parents to be the optgroup header.

Is use this structure
Parent

• sub child 1 (2 posts according to backend)
• sub child 2 (1 post according to backend)

But if I query for the child theme and check the count it always shows with NULL. In the WordPress Dashboard it shoes it correctly with 2 and 1.

Why not in the front end.

  $args = array(
          'hide_empty' => false, 
          'orderby' => 'name'
  );
      
  $ins = get_terms('indikationen', $args);

if($ins):
    echo "<select>";
    foreach($ins as $in):

      
        if ( count( get_term_children( $in->term_id, 'indikationen' ) ) > 0 ):
        echo '<optgroup label="'.$in->name.'">';
          foreach($ins as $sub):
            if($sub->parent == $in->term_id):
                echo "<option value='".$sub->term_id."'>".$sub->name. " count: ".$sub->count."</option>";
          // SUB-COUNT is always NULL but has correct count in backend
            
            endif;
          endforeach;
        echo '</optgroup>';
        
        else:
          if($in->count):
            echo "<option value='".$in->term_id."'>" .$in->name. " (".$in->count.")</option>";
          endif;
        endif;  
    
    endforeach;
    echo "</select>";
  endif;

What am I doing wrong?

var_dump($sub);
// shows me for count also NULL

Thanks
