我在处理一些计算时遇到了一些问题。我有一个产品页面，在该产品页面中，我有一些相关产品可以以折扣价作为一组购买。我一切正常，但在计算/折扣百分比中省略父产品时遇到问题。

下面的代码是从折扣中删除父产品，但是如果我将另一个组添加到购物车中，它只会省略第一个父项，而不是新添加的父项。

如何检查 $buy_together_id 并确认只有第一个具有唯一 ID 的产品从折扣计算中省略？

我最近添加的解决这个问题的代码是 if ($k != 0) 的两个实例，但同样它只检查第一个父级而不是所有父级。

谢谢，

您可以尝试向父产品添加一个标志，这将允许在循环中使用更可靠的条件

foreach ($products as $k => $v){
  if ($k != 0) {
     // ......
  }
}

而不是 if ($k != 0)。
