Вывод основной категории Ocstore во всем магазине

Recommended Posts

Есть проблема с выводом основной категории в Ocstore 2.1

Пишу в модель 


    public function getProductCategoryInfo($product_id){
        $query = $this->db->query("SELECT category_id FROM " . DB_PREFIX . "product_to_category WHERE product_id = '" . (int)$product_id . "' AND main_category = '1' LIMIT 1");
        $category = $this->getCategoryEs($query->row['category_id']);
        return $category['name'];

    public function getCategoryEs($category_id) {
        $query = $this->db->query("SELECT DISTINCT * FROM " . DB_PREFIX . "category c LEFT JOIN " . DB_PREFIX . "category_description cd ON (c.category_id = cd.category_id) LEFT JOIN " . DB_PREFIX . "category_to_store c2s ON (c.category_id = c2s.category_id) WHERE c.category_id = '" . (int)$category_id . "' AND cd.language_id = '" . (int)$this->config->get('config_language_id') . "' AND c2s.store_id = '" . (int)$this->config->get('config_store_id') . "' AND c.status = '1'");

        return $query->row;


Далее вывожу в контроллере 

$category_name = $this->model_catalog_category->getProductCategoryInfo($product_info['product_id']);

В массив   $data['products'][] = array(

 'category_name'       => $category_name,


Работает как надо - только если не присвоена основная категория то жалуеться на category_id и name    ( Notice: Undefined index: category_id in и  Undefined index: name in  )

Подскажите как пофиксить етот моммент
