I am trying to create a template changer for my site. The layout stays the same but the CSS changes the colors. I have it working and everything, but I need to use sessions to remember the CSS sheet chosen so that the person does not have to choose the template everytime they go to a new page. This is the code I am using:

CODE

<?php

    session_start();

    // Time to choose the layout! Since it is the same layout with different style sheets, just put the users choice into a session,
    // then add a default incase the user hasn't chosen anything.

    if (isset($_GET["css_form"])){
        $HTTP_SESSION_VARS["css"] = $_GET["css_form"];
        $css = $_GET["css_form"];
    } else {
        $css = "orange";
    }

    echo "<link rel='stylesheet' type='text/css' href='http://www.ephp.uni.cc/$css/style.css' title='Stylesheet'/>";


?>

And the form:

CODE

<form name="css_chooser" type="get">
            <select name="css_form">
            <option value="orange" selected> Orange
            <option value="green"> Green
            <option value="gray"> Gray
            <option value="pink"> Pink
            <option value="purple"> Purple
            <option value="red"> Red
            </select>
            <input type="submit" value="Go!">
            </form>

What should I do, becuase it isn't working.

And btw, where did you CODE button go?

if (isset($_POST['css_form'])){
$_SESSION['css'] = $_POST['css_form'];
} else {
$_SESSION['css'] = "orange";
}

echo '<link rel="stylesheet" type="text/css" href="http://www.ephp.uni.cc/'.$_SESSION['css'].'/style.css" title="Stylesheet" />';

?>

Now when I change it, it doesn't do anything. And also, it still has the get stuff at the top. Try it: http://www.ephp.uni.cc

It works, but when I select a colour from the index page then go to the test page by clicking the link it doesn't change and the BG is orange. Try it out at ephp.uni.cc.

I personally would use cookies for this.

I wanted to but I know even less about Cookies and PHP than Sessions and PHP.

FYI sessions use cookies

Make sure you add session_start(); at the top of every page, otherwise it will not read $_SESSION['css'];

Oh, I've never used sessions, heh- I've always used set cookie and if($_COOKIE['']) etc.
