Just wondering if anyone can help, I have this php system which is like a cms. You can have templates for it and download them etc

Im having a problem with a snippet of code which I have been given, which basically changes the theme of the site by switching templates.

Could you explain the code to me so I maybe then can understand where Im going wrong.

I have put this into a seperate php file -

PHP Code:

<?php
session_start();
$HTTP_SESSION_VARS[demohomepage] = "index$templatenumber" . ".php";
$HTTP_SESSION_VARS[demoheader] = "topmenu$templatenumber" . ".php";
$HTTP_SESSION_VARS[demofooter] = "footer$templatenumber" . ".html";
$HTTP_SESSION_VARS[demometa] = "meta$templatenumber" . ".html";
if( $templatenumber )
    $HTTP_SESSION_VARS[tabstyle] = "tngtabs1-$templatenumber" . ".css";
else
    $HTTP_SESSION_VARS[tabstyle] = "tngtabs1.css";
//tab style sheets must have tngtab.png graphics = tngtab-1.php, tngtab-2.php

if( substr( basename($HTTP_SESSION_VARS[demoreturn]), 0, 5 ) == "index" ) $HTTP_SESSION_VARS[demoreturn] = "index$templatenumber" . ".php";
header( "Location: " . $HTTP_SESSION_VARS[demoreturn] );
?>

now basically within index.php I call this via a href -

link - settemplate.php?templatenumber=2

Basically it seems to call it but doesnt change the template / theme.

Thank you immensely for any help!!!

Where you having any error output ???

Maybe register globals is off

change this statement from

if( $templatenumber )

to

if( $_GET['templatenumber'] )

And see if that works. (just a thought) everything else seems ok

I changed that, and no help.

I have set the settemplate.php into the root dir and then called all the other templates - index1.php, index2.php etc etc is this correct?

Any thoughts?

thank you so much!
