Хиты продаж по категориям

[morrowind]

Приветствую!
Проблема такая:
мне нужно сделать фильтрацию модуля "хиты продаж" по категориям. 

Есть вот такая функция:

 

public function getBestSellerProductsbyCate($category_id,$limit){
          if ($this->customer->isLogged()) {
			$customer_group_id = $this->customer->getCustomerGroupId();
		} else {
			$customer_group_id = $this->config->get('config_customer_group_id');
		}	
				
		$product_data = $this->cache->get('product.bestseller.' . (int)$this->config->get('config_language_id') . '.' . (int)$this->config->get('config_store_id'). '.' . $customer_group_id . '.' . (int)$limit);

		if (!$product_data) { 
			$product_data = array();
			
			$query = $this->db->query("SELECT op.product_id, COUNT(*) AS total FROM " . DB_PREFIX . "order_product op LEFT JOIN `" . DB_PREFIX . "order` o ON (op.order_id = o.order_id) LEFT JOIN `" . DB_PREFIX . "product` p ON (op.product_id = p.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) LEFT JOIN " . DB_PREFIX . "product_to_category p2c ON (p.product_id = p2c.product_id) WHERE o.order_status_id > '0' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "' AND p2c.category_id = '".$category_id."'  GROUP BY op.product_id ORDER BY total DESC LIMIT " . (int)$limit);
			
			foreach ($query->rows as $result) { 		
				$product_data[$result['product_id']] = $this->getProduct($result['product_id']);
			}
			
			$this->cache->set('product.bestseller.' . (int)$this->config->get('config_language_id') . '.' . (int)$this->config->get('config_store_id'). '.' . $customer_group_id . '.' . (int)$limit, $product_data);
		}
		
		return $product_data;
       }

и переписанный модуль хиты продаж:

 

.....
$this->load->model('catalog/category');
		$this->load->model('tool/image');
		
		$this->data['categories'] = array();
		
		$categories = $this->model_catalog_category->getCategories(0);



		foreach ($categories as $category) {

		if ($category['top']) {
  
		$products = array();		
		$results = $this->model_catalog_product->getBestSellerProductsbyCate($category['category_id']);
		
		foreach ($results as $result) {
			if ($result['image']) {
				$image = $this->model_tool_image->resize($result['image'], $setting['image_width'], $setting['image_height']);
			} else {
				$image = false;
			}
			
			if (($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) {
				$price = $this->currency->format($this->tax->calculate($result['price'], $result['tax_class_id'], $this->config->get('config_tax')));
			} else {
				$price = false;
			}
					
			if ((float)$result['special']) {
				$special = $this->currency->format($this->tax->calculate($result['special'], $result['tax_class_id'], $this->config->get('config_tax')));
			} else {
				$special = false;
			}	
			
			if ($this->config->get('config_review_status')) {
				$rating = $result['rating'];
			} else {
				$rating = false;
			}
							
			$products[$category['category_id']][] = array(
				'product_id' => $result['product_id'],
				'name'    	 => $result['name'],
			 
			);
		}
		 
 

		 
 



				// Level 1

				$this->data['categories'][] = array(

					'name'     => $category['name'],
					
					'products'     => $products,

					'column'   => $category['column'] ? $category['column'] : 1,

					'href'     => $this->url->link('product/category', 'path=' . $category['category_id'])

				);

			}

		}

.....

 

Вроде работает, но проблема в том что товары для всех категорий определяются из первой категории в массиве - вот пример получаемого массива из getBestSellerProductsbyCate:

 

Array ( [20] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [18] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [25] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [57] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [17] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [24] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [33] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) ) Array ( [34] => Array ( [0] => Array ( [product_id] => 47 [name] => HP LP3065 ) [1] => Array ( [product_id] => 43 [name] => MacBook ) ) )

 

Хотя HP LP3065 и MacBook  принадлежат только к категории id 20...
