Вывод в категории товаров закупочную цену - JoomShopping

А в категории товаров не вывелось ничего(...

А как выводите в категории? Там ведь нет $this->product.
Там скорее всего надо пробовать print_r($this->rows);, если до цикла, или print_r($product);, если внутри цикла.

В общем может кому понадобится...

В файле components/com_jshopping/templates/default/list_products/product.php
После блока с product_price_default добавил кусок кода:

<div class="product_buy_price">
      <?php
            $ids =$product->product_id;
            $db = &JFactory::getDBO();//Подключение к бд
            $Query = "SELECT product_buy_price FROM #__jshopping_products WHERE product_id=$ids ";
            $db->setQuery($Query);
            $prodid = $db->loadObjectList();
               foreach($prodid as $pr){
               if(isset($pr->product_buy_price)&& ($pr->product_buy_price > 0)){
                  $expr = $pr->product_buy_price;
                  print_r (formatprice($expr));
               } else{echo '';}
            }
      ?>
</div>

У меня все заработало!
