   <?php
   function post_child_of_cat($child_post_id, $categorie, $art)
   	{
   if ($art=='1'){
   		$cat_array = wp_get_post_categories($child_post_id);
   		foreach ($cat_array as $category)
   		{
   			if (cat_is_ancestor_of((int)$categorie, (int)$category))
   			{
   				return true;
   
   			}
   
   		}
   
   } Elseif ($art=='2')
   
   if (cat_is_ancestor_of((int)$categorie, (int)$child_post_id)or ($child_post_id == $categorie))
   			{
   				return true;
   
   			}
   
   return false;
   }
   /* ende der function */
   
   ?>
   
   <?php
   
   if ( is_category() ) {
   $catb = get_the_category();
   $catb = $catb[0];
   echo $catb->cat_id; 
   
             while ($catb != 0) {
             $titel = $catb.','.$catb;
   
             $catb = $catb->category_parent;
             }
             $titel2 = '<p class="w"> '.single_cat_title('', FALSE).'</p>';
             $quernavi= $titel.' &raquo; </p>'.$titel2;
              } 
   
   elseif ( is_single() ) {
   $cats = get_the_category();
   foreach ($cats as $catu) {
   $catu=$catu->term_id;
   echo '<br />post-kat '.$catu;
   		}
   }
   
   while ($catu != 0) {
   $catu = $catu->category_parent;
   }
   echo '<br />a '.$catu;
   /* echo '<br />'.$cat->category_parent;
   $category = get_the_category($cat); */
   echo '<br /> b '.$cats[0]->category_parent;
   ?>
