重写Wordpress URL

Question

Recently I changed my wordpress permalinks in an effort to make them more readable and inline with what other blogs have done, which is just having the postname at the end, however I am having some issues with the .htaccess required for redirecting the old permalinks back to the new ones.

The previous permalink structure I had in place is as follows:

http://domain.com/%category%/%post_id%-%postname%

Now I would like to change it to the following:

http://domain.com/%postname%

I have tried to do this with a URL Rewrite, however I am having no such luck unfortunately

RewriteRule ^/([^/]+)/(\d+)-([^/]+)/$ http://domain.com/$3 [L,R=301]

My knowledge of mod_rewrite is limited, very limited. I was wondering if anyone could help me out as to why this is happening, and what I can do to resolve it. I essentially would like it to redirect to the correct permalink, with the "Moved Permanently 301" error code (so Google doesn't get upset with me)

Thank you for any assistance

Answer 1

The regex looks right,
however it might be to do with the trailing slash in the URL

try:

RewriteRule ^/([^/]+)/(\d+)-([^/]+)/?$ http://domain.com/$3 [L,R=301]

That should work with or without the trailing slash in the URL

Answer 2

I might be wrong, but doesn't it work automatically with Wordpress? At least with posts - if you change the slug, the old slug still works but redirects to the new one with 301. Isn't it the same with permalinks - maybe you shouldn't even change anything?
