skins using cookies

Hi.  I'm using cookies so that the users on my site may select a 'skin't that they prefer to view.  It works great as it is...but uses querystrings which I'd like to avoid.  Ideally, I would like coloured boxes on every page and each colour represents a new skin.  Once selected it is stored in the cookie.

This is the cookiecheck page which is included on every page....
<?

$total_skins = 14;
$default_skin = 1;

  if (isset($_REQUEST['newskin'])) {
    $newskin=(int)$_REQUEST['newskin'];
    if ( ($newskin<1) OR ($newskin>$total_skins) ) $newskin=$default_skin;
  } elseif (isset($_REQUEST['skin'])) {
    $newskin=(int)$skin;
    if ( ($skin<1) OR ($skin>$total_skins) ) $newskin=$default_skin;
  } else $newskin=$default_skin;

  $skin=$newskin;
  setcookie ('skin', "", time() - 3600);
  setcookie('skin',$newskin,time()+(86400*365),'/');
  setcookie('skin',$newskin,time()+(86400*365),'/','.domesticat.net');
  $skin=$newskin;


    $headervar = "includes/header";
    $footervar = "includes/footer";
    $extension = ".php";
?>

So far...the html is like this with the headers and footers being part of the new skin.

<? include($headervar.$skin.$extension); ?><br>

<a href="index.php?newskin=1">Skin 1</a><br>
<a href="index.php?newskin=2">Skin 2</a><br>

<? include($footervar.$skin.$extension); ?>

How could I adapt this so that we don't use querystrings?

Thanks
:-)

Use javascript to set the skin cookie, with query strings as a fallback mechanism

<script language="javascript">
function useSkin(skin) {
    var nextYear = new Date();
    nextYear.setFullYear(nextYear.getFullYear() + 1);
    document.cookie = 'skin=' + skin + '; expires=' + nextYear;
    return false;
}
</script>

<a href="index.php?newskin=1" onclick="return useSkin(1);">Skin 1</a>

This method will work for both javascript and non-javascript browsers.  If a browser has javascript, the useSkin() function will return false, preventing the anchor tag from loading the new page.
