我正在创建在线商店，但我在购物车产品方面存在一些问题。
如果我添加2个产品相同且不同的产品尺寸 此产品仅显示最后添加到购物车。
示例我想要这样
产品：ABC
尺寸：XL
产品：SKSD
尺寸：L
我想要这样。
这是我的代码
order.php
<?php
include "connection.php";
$link = $_REQUEST['link_goods'];
$data_pr = mysqli_query($con,"select * from goods where link_goods='".$link."' ");
$pr = mysqli_fetch_object($data_pr);
