我为我的订单报告列表添加了以下 Opencart 模块... http://www.opencart.com/index.php?route=extension/extension/info&extension_id=3597&filter_search=order%20list%20filter%20model&page=4
我对“产品”列有疑问。如果有多个选项，产品名称会打印多次。因此，如果我得到一个具有三个选项的产品，则产品名称会打印 3 次。有没有办法解决这个问题？
我只想打印一次产品名称和型号，知道吗？
我将附上我现在得到的结果...
这是我的 sql 查询...
public function getOrders($data = array()) {
$sql = "select o.order_id,o.email,o.telephone,CONCAT(o.shipping_address_1, ' ', o.shipping_address_2) AS address,CONCAT(o.firstname, ' ', o.lastname) AS customer,o.payment_zone AS state,o.payment_address_2 AS block, o.payment_address_1 AS address,o.payment_postcode AS postcode,(SELECT os.name FROM " .
