How do I write a .htaccess rewrite rule to convert query strings to sharded URIs?

Is there a way to set a rewrite rule in htaccess that converts query strings to sharded URIs? For instance,

http://domain.com/controller/method/?a=1&b=2&c=3

should be rewritten as

http://domain.com/controller/method/a/1/b/2/c/3

All you have to do is uninstall? and replace & s and = s with /, but I'm not entirely sure how this all figured out in .htaccess ...

Not that it matters, but I am using PHP and CodeIgniter in Apache.

Why don't you put this logic in your CodeIgniter controller instead of doing it in .htaccess?



Check out the CodeIgniter User Guide for handling string strings and request urls.

If you want to do this in .htaccess you need to have mod_rewrite.

The rule is not too hard. I am giving you a minimal example and you need to tweak the regex to fix your needs.



RewiteRule ^/([a-z]+)/([a-z]+)$ /method/?$1=$2

This is what you could do:

RewriteCond %{THE_REQUEST} ^GET\ /[^?]*\?
RewriteCond %{QUERY_STRING} ^([^&=]+)=?([^&]*)&([^&=]+)=?([^&]*)&?(.*)
RewriteRule ^ %{REQUEST_URI}/%1/%2/%3/%4?%5 [L]
RewriteCond %{THE_REQUEST} ^GET\ /[^?]*\?
RewriteCond %{QUERY_STRING} ^([^&=]+)=?([^&]*)&?(.*)
RewriteRule ^ %{REQUEST_URI}?/%1/%2?%3 [L]
