Woocommerce 如果两个或三个产品一起添加到购物车中，则更改其价格。吴哥商业

下午好！ 请帮助我在woocommerce中实现此功能。 我有三个特定的产品（具有特定的ID 2、3、4）。 我需要确保在将其中两个添加到购物车时，它们的价格都会自动更改。例如，对于id为2的产品，价格设置为100美元，而对于id为3的产品，价格设置为200美元。 此外，当它们全部加在一起（其中三个）时，它们的价格都发生了变化：产品2=100；产品#3=200；产品#4=250

---

我还没有在任何地方找到类似的东西，因此我希望得到任何提示。

我自己设法解决了这个问题。 我确保我需要的产品在篮子里互相“监视”。如果其中一方“注意到”另一方，则两方的价格都会更新。 同样地，如果三个人同时在篮子里“看到”对方，价格也会更新。 它可能不是最好的代码，但它工作得很好

原始代码取自此资源，并由我为执行任务而修改。 （）

    if ( $in_cart ) {
        return true;
    }
    return false;
