заменить хранение в SESSION на COOKIE

нехватало кавычек
новый код:

Спойлер

PHP:

1. class plgJshoppingproductsJshopping_last_visit_product extends JPlugin {
2.  
3.     function onBeforeDisplayProductView($view) {
4.         $session = JFactory::getSession();
5.         $last_visited_products = $session->get('last_visited_products', array());
6.         if (isset($last_visited_products[$view->product->product_id])) {
7.             unset($last_visited_products[$view->product->product_id]);
8.         }
9.         $product = new stdClass();
10.         $product->name = $view->product->name;
11.         $product->product_thumb_image = $view->product->product_thumb_image;
12.         $product->product_id = $view->product->product_id;
13.         $product->currency_id = $view->product->currency_id;
14.         $product->product_price = $view->product->product_price;
15.         $product->product_manufacturer_id = $view->product->product_manufacturer_id;
16.         $product->label_id = $view->product->label_id;
17.         $product->category_id = $view->category_id;
18.         $last_visited_products[$product->product_id] = $product;
19.         $session->set('last_visited_products', $last_visited_products);
20.  
21.         $patch = "/";
22.         if (JURI::base(true) != ""){
23.             $patch = JURI::base(true);
24.         }
25.         setcookie('last_visited_products', session_id(), time() + 3600*24*30, $patch);
26.  
27.         $inputCookie  = JFactory::getApplication()->input->cookie;
28.         $cookie_id = $inputCookie->get('last_visited_products', null);
29.         $cookieExists = ($cookie_id === null);
30.  
31.         $db = JFactory::getDbo();
32.  
33.         $query = "INSERT INTO `oewi4_jmb_jshopping_last_seen_products` (`product_id`, `time`, `data`)"
34.             . " VALUES ('" . $db->escape($cookie_id) . "', NOW(), " . $db->quote(json_encode($last_visited_products)) . ")"
35.             . " ON DUPLICATE KEY UPDATE `time` = VALUES(`time`), `data` = VALUES(`data`)";
36.  
37.         $db->setQuery($query);
38.         $db->execute();
39.     }
40.  
41. }

как теперь это выводить используя как ключ кукисы?
