everything is working exept in the very first loading of the page there isnt any style, but why?
the error is Undefined index: css in C:\wamp\www\index.php on line 6. i can understand that theres no value but why?
also when i click the christmas style link i have to press reload to get it
stylechooser.php file looks like this:
<?php
$switch = (isset($_GET['mode'])) ? $_GET['mode'] : "index";
switch($switch) {
#option 1
case "christmas":
$css = "/christmas.css";
#setting session.
$_SESSION['css'] = $css;
break;
#option 2
case "fancy":
$css = "/fancy.css";
$_SESSION['css'] = $css;
break;
#reset to the default
default:
$css = "/default.css";
$_SESSION['css'] = $css;
break;
}
?>
And the index.php-s beginning looks like this :
<html>
<head>
<?php
session_start();
echo "<link rel=\"stylesheet\" type=\"text/css\" href=\"{$_SESSION['css']}\" media=\"screen\">";
?>
</head>
<title></title>
<body>
<?php include("style_chooser.php");?>
<?php include("visits.php");?>
<a href='?mode=christmas'>here</a>
