问题 How can I show all posts with a specific category foo and a specific tag bar by using URL? Example: site.com/category/foo/tag/bar or Example: site.com/posts?category={category-id}&tag={tag-id} 回答1: I don't know is there as default feature for the this or not but I have an idea as how to achieve it.
