这里有以下情况：

自定义帖子类型：“recipes”自定义帖子类型“recipes”的分类法：“receitas”分类法之一slug：“receitas whoopie”permalink结构必须为：

示例。com/receitas（显示自定义帖子类型“recipes”的所有帖子……如果需要，它可以是页面模板）
示例。com/receitas-whoopie（显示分类法“recipescat”->“receitas-whoopie-pie”下自定义帖子类型“recipes”的所有帖子）
示例。com/receitas-whoopie/post\\u name（在分类法“receitas”->“receitas-whoopie-pie”下显示单数帖子）

我尝试了许多通过过滤器实现这一点的方法，这是唯一有效的方法，访问/收据为whoopie派/post\\u名称

实际上，我有以下结构：


不管这个问题如何，我的函数：
示例。com/receitas（显示自定义帖子类型“recipes”-页面模板的所有帖子）
示例。com/receitas/receitas-whoopie（显示分类法“recipescat”->“receitas-whoopie-pie”下自定义帖子类型“recipes”的所有帖子）
示例。com/recipes/post\\u name（在分类法“receitas”->“receitas-whoopie-pie”下显示单数post）
