 * Hi
    This is my first post so bare with me if this has already been posted in 
   this forum. At my blog I have started with a new design. I would like to have
   the frontpage as one design and all the other pages, as another. My idea was 
   to make use of the isset php function. When you first enter the page the url 
   would without any vars. When the user hits an article or search the vars are 
   set in the url like this cat=20. The function I made was an if function, if an
   var is set it would write id=contentpage if not it would write id=”frontpage”.
   I just made an testpage wich do not have anyting to do with WP and then it work.
   The code is also on this page [http://www.jedisthlm.com/var.php](http://www.jedisthlm.com/var.php)
   and [http://www.jedisthlm.com/var.php?cat=20](http://www.jedisthlm.com/var.php?cat=20)
   When I then add the code to my index.php file it does not work. [http://www.jedisthlm.com/index-utv.php](http://www.jedisthlm.com/index-utv.php)
   and [http://www.jedisthlm.com/index-utv.php?cat=20](http://www.jedisthlm.com/index-utv.php?cat=20)
   Anyone knows what I am doing wrong?

 * I think you have to use isset with the rest of the variables like:
    isset($p)
   || isset($cat) || isset($s) || isset($static)

    I used the QUERY_STRING function and now it
   works like a charm. 😀
