我们有一个销售旅行团的 WooCommerce。问题是，一位游客可以为四个人购买旅行团，或者旅行中的每个人都可以得到他们的passport_number 和expiration_date。
现在我们可以很容易地在结帐页面中显示所需的字段，但是必须有购买的产品（旅游）数量的条件。
我做了很多研究，我只能找到基于product_id的条件字段，但没有基于产品的数量，所以我希望这个问题对其他人有所帮助。
非常感谢任何帮助或指导。

您似乎问了很长时间，但我会为将来可能需要它的人添加它。这是我们解决此问题的完整代码。
此代码假定购物车上选择的商品只是其中一个包裹，而不是它们的混合。然后客户可以选择他们想要的乘客数量。
