Set and use a variable to control page Colors

reach100 · 08-07-2008, 10:11 PM

Hi There, I would like to build a page that displays a certain image, and background color based on a variable sent in the URL string. Can someone please give me a simple explanation on how to do this?

Here is a link to my test page...
http://dev.tommybaynard.com/sample_page.php?ID=A1

I would like the variable A1 to determine that image 1.jpg will be used, and that #7F8F91 is the background color.

Any suggestions are welcome, thanks.

Simple way.

PHP Code:


			
<?php

$id = $_GET['ID'];



switch($id){

    case 'A1':

        $bgcolor = '#7F8F91';

        $image = '1.jpg';

    break;

    

    case 'A2':

        $bgcolor = '#FF9999';

        $image = '2.jpg';

    break;



    default:

        $bgcolor = '#FFFFFF';

        $image = 'defaultimage.jpg';

}

?>

<html>

<head>

<style>

body{

        background-color:<?php echo $bgcolor; ?>;

    }

</style>

</head>

<body>

<img src="images/<?php echo $image; ?>" />

</body>

</html>

Thanks! that worked great for me.
Do you have any idea how I could use this to update a page, WITHOUT having to reload the page? I just want a link to update the background and image on the fly.
Thanks,
Rich

You'll need to use javascript to do that. Take a look on dynamicdrive or something, there should be a script on there that can be modified
