wordpress WooCommerce中基于用户角色的不同产品变化价格

场景

2个类别的7个自定义角色被构建为服务于具有订阅的B2C客户和B2B分销商，它们是：

B2C subcription_tier1 / subcription_tier2
B2B distributor_tier1 / distributor_tier2 / distributor_tier3 / distributor_tier4 / distributor_tier5

当用户登录时，用户可以看到他们的层的不同折扣：

B2C类别（subcription_tier）中的用户可以查看其角色的折扣价格
B2B类别（distributor_tier）中的用户能够看到其角色的折扣价格，但仅限于我们可能为他们提供有竞争力的价格的产品，或告知他们由于我们没有资格提供优质价格而无法分发该产品的文本

取得的成就

通过添加本教程中的代码片段，我已经实现了简单产品的目标。该解决方案仅使我能够通过使用ACF和一些代码片段来完成简单产品的需求，而不是变量。

代码

经过几天的研究，LoicTheAztec的一个很好的解决方案来自this post的见解。然而，我发现自己陷入了建立自定义价格和角色之间的联系（* 我不是工程师，仍在学习如何编码以减少插件的依赖性 *）。

字符串
自定义空白字段在后端设置，但在前端具有所需分层角色的登录用户看不到它们。
我已经尽了最大的努力来建立正确的逻辑，这是我有限的编码知识所能达到的最远的地方。我知道我一定错过了一些东西（或一些东西）或做错了什么，但我真的不知道在哪里审计以使其正确。
感谢您提前回复。期待您的帮助。
