这让我抓狂，我相信这很简单，但我搜索的东西都没有简单的结构（一切都很复杂）。

我有一个自定义的帖子类型product_listing 和自定义分类法product_cat （这是分层的，应该有相似的类别）。

我只是希望我的URL如下所示：

mysite.com/products/category1/product-name1 
mysite.com/products/category2/product-name2

但就我的一生而言，无论我做什么，我都会遇到令人恐惧的404问题。页面工作正常，帖子工作正常，但我的自定义帖子无法正常工作。他们表现为：

mysite.com/products/product-name1
mysite.com/products/product-name2

这实际上是有效的！我只是想在那里看到我的自定义分类法，而且我想能够访问taxonomy.php 我已通过转到以下位置设置模板：

mysite.com/products/category1/
mysite.com/products/category2/

我的鼻涕虫都不一样，我也不希望它们是一样的。这是我的functions.php 文件：

}

我还有另一个自定义分类法scents 理想情况下，我希望有一些友好的url，但我对此持开放态度。我想通过访问mysite.com/products/scents 但它们不必是特定类别的。

有人能帮我吗？
