Question

I need to create a function for WP that will check if the current category is both child of X category and parent to Z category.

Ideas?

Answer 1

I finally got to write this simple solution for getting both Parent and Children form the current viewed category in WordPress:

  $children = $wp_query->query_vars[category__in];
  $count = 0;

  echo 'Parent: ' . $wp_query->queried_object->parent;
        echo ' | ';
  echo 'Children: ';

  foreach ($children as $child) { 
   if (($wp_query->query_vars[category__in][$count]) != ($wp_query->query_vars[cat])) {
     echo $wp_query->query_vars[category__in][$count];
     echo ' ';
    }
   $count++;
  }
