Question

理想情况下，对具有给定标签的所有产品和变体给予20％的折扣，然后正确显示它。

现在我有一个控制实际价格的插件，我正在尝试更改价格的直观显示方式...

我想出了部分解决方案来更改商店和单个产品页面中的显示价格。

有人可以清理吗？它会引发致命错误，但会产生预期的效果。...希望更改商店和单个产品页面上具有给定标签的产品的显示价格。

Answer 1

我无法在此处测试代码，但我将从一个简单的

开始

if (is_null($product)) return $price;

此行之后：

global $product;

更改带有标签的产品在商店和单个产品页面上显示的价格
