我目前使用的是Avada主题，该主题利用了作为投资组合类别的自定义帖子类型；投资组合项目（属于一个或多个类别的一部分）。

该主题提供了使用固定slug“前缀”的解决方案（如图所示here). 此解决方案转换为如下url：www.domain.com/fixed-prefix-here/portfolio-item-title

我想尝试的是动态设置固定前缀，将其设置为该自定义帖子的类别。

F、 e.投资组合项目“测试”的段塞，其类别为“类别测试”，应为：www.domain.com/category-test/test

我对WordPress开发相当陌生，而不是PHP。欢迎任何帮助。非常感谢。

EDIT:

Try #1 我将“固定slug”设置为自定义分类法%portfolio_prefix% 并在保存自定义分类法后在函数中替换它（请参见代码段）。这样就可以了，单个帖子会显示自定义url，打开后帖子会正确加载。不幸的是，当我出于某种原因打开它们时，我的单页崩溃了。欢迎提供任何提示。
