Mod_Rewrite change GET value pairs into nice slashes.

Question

I have a url http://domain.com/module/controller/action/get1/value1/?get2=value2&get3=value3 I want to use Mod_Rewrite to change the ?&= to appropriate / slashes inline with the first GET variable.

I also need to avoid conflicts with my current Mod_Rewrite rules:

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

Answer 1

If you don't need the GET parameters in their native $_GET container, you could leave the htaccess file as is, and have the front controller (I assume you are using PHP) do the parsing and not mod_rewrite.

You would have to access the $_SERVER["REQUEST_URI"] and parse out the parameters before any other URL parsing (I think you are using the Zend Frameworks') kicks in.

This works only if you can modify the part of your program that needs value1 value2 value3 etc. If it's some Zend component that needs the parameters, and that component fetches them directly from $_GET, this will not work for you and you may in fact have to build mod_rewrite instructions.

Btw, you are aware by the way that with the method in your .htaccess, invalid links to images, CSS files and other media types will all be routed to zend.php?

Try putting these rules in front of yours:

RewriteCond %{QUERY_STRING} ^([^&=]+)=([^&]+)&(.+)
RewriteRule ^ %{REQUEST_URI}%1/%2/?%3 [N]
RewriteCond %{QUERY_STRING} ^([^&=]+)=([^&]+)$
RewriteRule ^ %{REQUEST_URI}%1/%2/? [L,R]

Answer 3

I could not find a nice way to do this... so I resolved to write some minimised PHP code at the top of my zend.php.

list($sURL, $sQuery) = explode('?', $_SERVER['REQUEST_URI']);
$sOriginalURL = $sURL;
if ('/' !== substr($sURL, -1)) $sURL .= '/';
if (isset($sQuery)) {
    foreach (explode('&', $sQuery) as $sPair) {
        if (empty($sPair)) continue;
        list($sKey, $sValue) = explode('=', $sPair);
        $sURL .= $sKey . '/' . $sValue . '/';
    }
}
if (isset($sQuery) || $sOriginalURL !== $sURL) header(sprintf('Location: %s', $sURL));
