Theme selection from URL
 

Hi

I am looking at trying to change / select the phpws v0.10.2 theme based upon whatever is written in the link from referrer site.

For example if link from referrer site contains ?theme=yellow* yellow theme shall be shown and displayed throughout all my site pages for that visitor..... if link from referrer site contains ?theme=red* red theme shall be shown and displayed throughout all my site pages for that visitor and so on

what I am looking at doing is kind of achieved here ((((((http://themes.kiesler.at/)))))) if you click on a phpws theme from the list it changes the theme using a url call / ?theme=

Anyone got any ideas on how to get this working.

Many thanks
