Rewrite query string "?x=y" style to "/x/y" style

I have a PHP MVC framework I've built from scratch which uses the traditional domain.com/controller/action URL routing. While I'm currently handling the below conversion in the router I'd like to replace them in the URL for cosmetic reasons.

For example:

controller/action?filter=bank

Becomes:

controller/action/filter/bank

I've done a bit of experimentation with a regex but can't se开发者_Go百科em to find a match. I'm also not sure how to rewrite it using RewriteCond.

Thanks in advance.

You should take a look at some of the questions on clean-urls, mod-rewrite and .htaccess.

HTAccess - Confusing clean url's

Getting two variables in the URL with htaccess

Needs some help with an apache mod-rewrite issue

The Zend Framework URL format is nearly identical to this, and here's what they use:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ /index.php [NC,L]

If your server-side script is PHP, you could use this to grab the url parts:

$request_parts = explode('/', $_SERVER['REQUEST_URI']);
$controller = $request_parts[0];
$action = $request_parts[1];
// etc...

Based on your response to my other answer, I propose that you use JavaScript to handle the filter form submit and create the "clean url" request on the client side.

EDIT

I recently implemented this on my Year/Month picker for my calendar application. It uses jQuery/JavaScript to detect changes in the form and write the "clean" URL:

$(document).ready(function() {
    $('form.jumpform select').change(function() {
        $form = $(this).closest('form');
        window.location = $form.attr('action')
                + '/y/' + encodeURIComponent($form.find('select[name="y"]').val())
                + '/m/' + encodeURIComponent($form.find('select[name="m"]').val());
    });
});
