SIMPLE php problem Thread

Hello,

I am currently trying to introduce simple theming into a forum I am coding, I figured the easiest way todo this was using various CSS.

<link rel="stylesheet" href="includes/styles/<?PHP echo $_COOKIE['theme'] ?>.css" type="text/css">

In the header before the HTML begins I have this code...

if(!$_COOKIE['theme'] || $theme)
{$first= 1;
if($theme == "wuggy")
{$second = 2;
setcookie ("theme", "default", time()+60*60*24*30,'/','.wuggawoo.co.uk', 0);}
elseif($theme == "forumz")
{$third = 3;
setcookie ("theme", "forumz", time()+60*60*24*30,'/','.wuggawoo.co.uk', 0);}}
else
{$forth = 4;}

The first second third and forth are there for debug reasons because its not working properly.

Go test for yourself ; Forumz.wuggawoo.co.uk - adding ?theme=forumz or ?theme=wuggy works once, and only once, but then the cookie wont get over-ridden...any help is appreciated.

Are you determined that the theme value will come from a cookie? You have user information in your database--why not just add an attribute for the user's theme of choice?

Anyway, how about this?

if ( $_GET['theme'] ) // changing theme takes precedence
{
  $theme = $_GET['theme'];
}
else if ( $_COOKIE['theme'] )
{
  $theme = $_COOKIE['theme'];
}
else
{
  $theme = "default";
}
setcookie( "theme", $theme, time()+60*60*24*30, "/", ".wuggawoo.co.uk", 0 );



... blah blah ...



<link rel="stylesheet" type="text/css" href="/includes/styles/<?= $theme ?>.css">

Nick helped me out and got it working great...

if($submitted == true)
{setcookie("theme", "theme:$tc", time()+604800, "/");
header("Location: $HTTP_REFERER");}

if(!$_COOKIE['theme'])
{setcookie("theme", "theme:default", time()+604800, "/");
header("Location: index.php");}
else
{global $theme;
$session_vars = explode(":", $theme);} 

Then where the CSS bit is we use...

<link rel="stylesheet" href="includes/styles/<? echo $session_vars[1]; ?>.css" type="text/css">

and the drop down box is simply just

<form name="form1" method="post" action="index.php"  style='margin-top : 0px;margin-bottom : 0px;'> Wuggawoo forum
<select name="tc" class='textfield' onChange="document.form1.submit();">
<option value="default">-Select-</option>
<option value="default">Forumz</option>
<option value="wuggawoo">Wuggawoo</option>
</select>
<input name="submitted" type="hidden" value="true">
</form>

thx anyway!
