mod_rewrite with multiple query strings?

Question

I'm trying to cleanup some URLs on my blog, so I've decided to look into mod_rewrite. I haven't a clue what I'm doing though, so I was hoping I could get some help :P I have links like http://kn3rdmeister.com/blog/post.php?y=2012&m=07&d=04&id=4. Although it works, and people still get the content I want them to have, I don't like them having to look at all the query strings. I want to turn the above link into http://kn3rdmeister.com/blog/2012/07/04/4.php.

This is what my .htaccess looks like right now.

RewriteEngine On
RewriteCond %{QUERY_STRING} ^y=([0-9){4})&m=([0-9]{2})&d=([0-9]{2})&id=([0-9]*)$
RewriteRule ^/blog/post\.php$ http://kn3rdmeister.com/blog/%1/%2/%3/%4.php? [L]

Like I said, I'm absolutely clueless :D

Answer 1

If you're using apache 2.0 or higher, you're going to need to remove the leading slash (the prefix) if these rules are in an .htaccess file, so that your regular expression looks like this:

# also note this needs to be a "]"--v
RewriteCond %{QUERY_STRING} ^y=([0-9]{4})&m=([0-9]{2})&d=([0-9]{2})&id=([0-9]*)$
RewriteRule ^blog/post\.php$ http://kn3rdmeister.com/blog/%1/%2/%3/%4.php? [L]

This is going to make it so when someone puts http://kn3rdmeister.com/blog/post.php?y=2012&m=07&d=04&id=4 in their browser's URL address bar, their browser will get redirected to http://kn3rdmeister.com/blog/2012/07/04/4.php and the new URL will appear in their address bar.

I assume you've got something setup on your server to handle a request like blog/2012/07/04/4.php.
