htaccess rewrite turn all "folders" into request variables, almost got it!

Question

Here's what I have now:

Options +FollowSymlinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)(.*)$ /$3?$1=$2 [N,QSA]

This turns www.any.com/x/20/y/30 into www.any.com/index.php?x=20&y=30
(while ignoring existing directories - thank you so much Gumbo!!)

RewriteRule ^([^/]+)/([^/]+)(.*)$ /$3?$1&$2 [N,QSA]

This tweak allows me to go: www.any.com/x/y=30 and accomplish the same results but with x having no value. I love having this option, but I have to do two variables at a time or I get a page not found for the odd variable. So www.any.com/x/y=20/z would give me "url /z not found!"

Any thoughts on how I can get it to rewrite basically every folder into a request variable? Thanks, guys.

Answer 1

Try these rules:

RewriteCond %{REQUEST_FILENAME} -f  [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]

RewriteRule ^([^/=]+)=([^/]*)(/(.+))?$ /$4?$1=$2 [N,QSA]
RewriteRule ^([^/=]+)/([^/=]+)(/(.+))?$ /$4?$1=$2 [N,QSA]
RewriteRule ^([^/=]+)(/(.+))?$ /$3?$1 [N,QSA]

The first is to abort the rewriting process if request can be mapped on an existing file or directory. The second rule is for URL paths of the form /foo=bar/… → /…?foo=bar. The third is for URL paths of the form /foo/bar/… → /…?foo=bar. And the fourth is for URL paths of the form /foo/… → /…?foo.
