Sort by name accessories of products

[kettlerbasic]

Hello to all, I have a big problem with the accessories sort in my products, because sort by id and I need sort by name.

 

I read in other forum about SORT BY command, I I dont know Where exactly does it go, can someone help me? thank you very much

 

My code in classes/product.php is:

 

    public function getAccessories($id_lang, $active = true)
    {
        $sql = 'SELECT p.*, product_shop.*, stock.out_of_stock, IFNULL(stock.quantity, 0) as quantity, pl.`description`, pl.`description_short`, pl.`link_rewrite`,
                    pl.`meta_description`, pl.`meta_keywords`, pl.`meta_title`, pl.`name`, pl.`available_now`, pl.`available_later`,
                    image_shop.`id_image` id_image, il.`legend`, m.`name` as manufacturer_name, cl.`name` AS category_default, IFNULL(product_attribute_shop.id_product_attribute, 0) id_product_attribute,
                    DATEDIFF(
                        p.`date_add`,
                        DATE_SUB(
                            "'.date('Y-m-d').' 00:00:00",
                            INTERVAL '.(Validate::isUnsignedInt(Configuration::get('PS_NB_DAYS_NEW_PRODUCT')) ? Configuration::get('PS_NB_DAYS_NEW_PRODUCT') : 20).' DAY
                        )
                    ) > 0 AS new
                FROM `'._DB_PREFIX_.'accessory`
                LEFT JOIN `'._DB_PREFIX_.'product` p ON p.`id_product` = `id_product_2`
                '.Shop::addSqlAssociation('product', 'p').'
                LEFT JOIN `'._DB_PREFIX_.'product_attribute_shop` product_attribute_shop
                    ON (p.`id_product` = product_attribute_shop.`id_product` AND product_attribute_shop.`default_on` = 1 AND product_attribute_shop.id_shop='.(int)$this->id_shop.')
                LEFT JOIN `'._DB_PREFIX_.'product_lang` pl ON (
                    p.`id_product` = pl.`id_product`
                    AND pl.`id_lang` = '.(int)$id_lang.Shop::addSqlRestrictionOnLang('pl').'
                )
                LEFT JOIN `'._DB_PREFIX_.'category_lang` cl ON (
                    product_shop.`id_category_default` = cl.`id_category`
                    AND cl.`id_lang` = '.(int)$id_lang.Shop::addSqlRestrictionOnLang('cl').'
                )
                LEFT JOIN `'._DB_PREFIX_.'image_shop` image_shop
                    ON (image_shop.`id_product` = p.`id_product` AND image_shop.cover=1 AND image_shop.id_shop='.(int)$this->id_shop.')
                LEFT JOIN `'._DB_PREFIX_.'image_lang` il ON (image_shop.`id_image` = il.`id_image` AND il.`id_lang` = '.(int)$id_lang.')
                LEFT JOIN `'._DB_PREFIX_.'manufacturer` m ON (p.`id_manufacturer`= m.`id_manufacturer`)

                WHERE `id_product_1` = '.(int)$this->id.
                ($active ? ' AND product_shop.`active` = 1 AND product_shop.`visibility` != \'none\'' : '').'
                GROUP BY product_shop.id_product';

        if (!$result = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS($sql)) {
            return false;
        }

        foreach ($result as &$row) {
            $row['id_product_attribute'] = Product::getDefaultAttribute((int)$row['id_product']);
        }

        return $this->getProductsProperties($id_lang, $result);
    }

    public static function getAccessoryById($accessory_id)
    {
        return Db::getInstance()->getRow('SELECT `id_product`, `name` FROM `'._DB_PREFIX_.'product_lang` WHERE `id_product` = '.(int)$accessory_id);
    }
