Problem rewriting dynamic URLs using mod_rewrite

I'm trying to rewrite a dynamic URL using the following code:

RewriteRule (.*)/$ index.php?location=$1  
RewriteRule (.*)/(.*)/$ index.php?location=$1&company=$2

I really need two rewrites as you can see from the above code. First, I need the page to rewrite just the location if that's all there is. For example, it would turn site.ccom/index.php?location=sandiego into site.com/sandiego/

This is working correctly.

However, when I try to add in the second variable it fails. It manages to detect the &company=1 variable, but for some 开发者_StackOverflowreason it returns the ?location=sandiego variable as 'index.php'. For example, if I input the following: site.com/san-diego/1/ and then try to grab the $location and $company variables, it will only get the $company variable successfully, and the $location variable will be set to 'index.php', rather than 'san-diego'.

Any help would be greatly appreciated.

I think I found the solution. I'm using the following:

RewriteRule ^([a-z0-9-]+)/?$ index.php?location=$1 [NC]
RewriteRule ^([a-z0-9-]+)/([a-z0-9-]+)/?$ index.php?location=$1&company=$2 [NC]

This seems to be working perfectly, and is successfully redirecting both site.com/sandiego/ and site.com/sandiego/1/

Try those:

RewriteRule ^([a-z0-9]+)/?$    index.php?location=$1 [NC]
RewriteRule ^([a-z0-9]+)/([a-z0-9]+)/?.*$    index.php?location=$1&company=$2 [NC]

Keep in mind that trying to capture any sequence of characters (by using for example (.*) or (.+)) when doing URL rewriting, is usually a bad idea, as explained in this thread : http://www.sitepoint.com/forums/apache-configuration-199/rewrite-eliminate-trailing-slash-arbitrary-parameters-520302.html#post3657601

Try  ([^\/]*)/([^\/]*)/$  instead of (.*)/(.*)/$
