我有一个产品的标准价格，另外还有6件装（5％折扣）和24件装（10％）折扣的价格。但是，这不是标准的批量折扣，数量6-23给予5％的折扣，然后24个以上的所有人都享有10％的折扣-7的价格为5％的折扣为6，全价的价格为1 ... 30的成本24折价10％，折价5％折价6，33折价10％6折价5％，折价3折价。24
这就是我所拥有的，而且我不确定自己在哪里出了问题，我认为我的逻辑是正确的（我尽了最大的努力来评论自己的想法）-检查24，如果有剩余数量，则对6进行检查，然后在剩余数量上应用单个价格。
我将此添加到了子主题的functions.php中，当我单击以将产品添加到购物车时，它不断旋转，并在控制台中给我一个添加到购物车的ajax错误。谁能指出我要去哪里了吗？
