Discuss: Build a PHP Switcher

by Chris Clark

81 Switcher doesn't work (with me)

Hi there, I’m trying to use this code to switch styles on my website. I have used ALA’s Javascript switcher before, and it worked. But I can’t get the PHP version to work! I followed the tutorial step by step, and checked everything I could. It just shows plain text without any stylesheet (even if I let it show the default one). My server runs PHP and other scripts work perfectly.

Can anyone please help me? Greetings from the Netherlands,

Nick

83 stats on JS/Cookie usage?

So we cater for those that have JavaScript deactivated
by relaying on the user accepting cookies…

Does anybody has statistical data on this?

84 A better way???

I tried to implement the code given by Peter Hawkes and all works fine after the first click… the first time visiting the page, I get:

Notice: Undefined index: csschanger in c:\hosting\webhost4life\member\braincre\sean\new\index.php on line 32

anyone know why?

85 Session switcher

I am using the switcher by peter hawkes:

here is more chance that a user will have cookies disabled than JavaScript disabled. All the above will not work without cookies.
I am using SESSIONS in my version, this script assumes that PHP 4.2+ is installed and that register_globals is off with —enable-trans-sid.

Code as below:

<?php
session_start();
?>
<?php
if(isset($_GET[‘css’])){
switch ($_GET[‘css’]) {
case ‘css1’:
$stylesheet = ‘<link href=“theme1.css” type=“text/css” rel=“stylesheet”>’;
$_SESSION[‘csschanger’]=$stylesheet;
break;
case ‘css2’:
$stylesheet = ‘<link href=“theme2.css” type=“text/css” rel=“stylesheet”>’;
$_SESSION[‘csschanger’]=$stylesheet;
break;
case ‘css3’:
$stylesheet = ‘<link href=“theme3.css” type=“text/css” rel=“stylesheet”>’;
$_SESSION[‘csschanger’]=$stylesheet;
break;
case ‘css4’:
$stylesheet = ‘<link href=“theme4.css” type=“text/css” rel=“stylesheet”>’;
$_SESSION[‘csschanger’]=$stylesheet;
break;
default:
$stylesheet = ‘<link href=“cssdefault.css” type=“text/css” rel=“stylesheet”>’;
$_SESSION[‘csschanger’]=$stylesheet;
}
}
?>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html >
<head>
<title>CSS Changer</title>
<meta http-equiv=“Content-Type” content=“text/html; charset=iso-8859-1” />
<?php echo ($_SESSION[‘csschanger’])? $_SESSION[‘csschanger’]: ‘<link href=“cssdefault.css” type=“text/css” rel=“stylesheet”>’ ;?>
</head>

<body>
[url=”<?php echo $_SERVER[‘PHP_SELF’]; ?>?css=css1”]Stylesheet 1[/url]

[url=”<?php echo $_SERVER[‘PHP_SELF’]; ?>?css=css2”]Stylesheet 2[/url]

[url=”<?php echo $_SERVER[‘PHP_SELF’]; ?>?css=css3”]Stylesheet 3[/url]

[url=”<?php echo $_SERVER[‘PHP_SELF’]; ?>?css=css4”]Stylesheet 4[/url]

</body>
</html>

BUT.. Is there a way of doing it so it validates??

I have put this code as one file and used then included it each page.. can i change the style changer links to something like :
<a href=”/assets/includes/switcher.php?=masterm”
