Passing variable through subdomain wildcard redirect?

Question

I am working on a new script that basically instead when somebody searches for something on my website how it normally goes to here:

http://domain.com/index.php?q=apples

to

http://apples.domain.com

I have made this work perfectly in PHP as well as htaccess but the problem I am having is using the original keyword afterwards on the new subdomain page.

Right now I can use parse_url to get the keyword out of the url but my script also filters out potential problems like:

public function sanitise($v, $separator = '-')
    {
        return trim(
            preg_replace('#[^\w\-]+#', $separator, $v),
            $separator
        );
    }

So if somebody searches for netbook v1.2

The new subdomain would be:

http://netbook-v1-2.domain.com

Now I can take the keyword out but it's with the dashes and not original. I am looking for a way to send over the original keyword with the 301 redirect as well.

Thanks!

Have you tried using sessions? – jeroen Feb 21 '12 at 21:42 — jeroen, Feb 21 '12 at 21:42

You can either just replace the hyphen with spaces when they visit the new subdomain or, since you're on the same top-level domain, you can just cookie the keyword when redirecting them:

setcookie('clientkeyword', 'netbook-v1-2.domain.com:netbook v1.2', 0, '/', '.domain.com');

Works great when people are searching for the item themselves, but if a user clicks on apples.domain.com from google or something, nothing would show. :( – deadlyeffect Feb 21 '12 at 22:04
That's why I also stated `just replace the hyphen with spaces` from `$_SERVER['HTTP_HOST']`. There's nothing else you can do in that case. – webbiedave Feb 21 '12 at 22:08
After thinking about it, you are absolutely right. There is nothing else I can do about it so this should be good enough. Thank you! – deadlyeffect Feb 21 '12 at 22:11

Look at this answer: https://stackoverflow.com/a/358334/992437

And see if you can use the POST or GET data that's already there. If so, that might be your best bet.

That specific flag in the .htaccess tells the POST data and GET data to be redirected as well. Am I missing something? – Tango Bravo Feb 21 '12 at 21:45
You're confusing rewrite with redirect. The client will not repost its data. – webbiedave Feb 21 '12 at 21:47
I must be completely confused. But from my experience, RewriteRule's can redirect as well ([L,R=301]). That's part of what they do. I'll look into this more though, as I might have missed something. – Tango Bravo Feb 21 '12 at 22:03
