The title may be a little confusing, I don't know how to word it to be short.
Right now my permalink structure is
/%post_id%/%postname% so the final URL is
When I go to
domain.com/post_id then it redirects to
domain.com/post_type/%post_id%/%postname% but when I got to
domain.com/post_type/post_id it doesn't redirect but shows the correct post.
I'm not sure how to make it work the way the default redirect works.
