Session variable being set on my PC but not on webhost's server

Hi all,

 

I have the following code to check whether the client has javascript enabled in their browser:

 

page.php:

<?php
session_start(); 
if(isset($_SESSION['gocheck'])) {$gocheck = $_SESSION['gocheck'];} else {$gocheck = 'no';}
//echo $gocheck;
if($gocheck=='no'){header ("Location: ./gocheck.php"); exit;}
//----Execution only reaches this line if gocheck.php has been run and Javascript is enabled.--------
unset($_SESSION['gocheck']);
//rest of page
?>

 

gocheck.php:

<?php
session_start(); 
$_SESSION['gocheck'] = 'yes';

echo"
<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\" lang=\"en\">
<head>
<script type=\"text/javascript\" language=\"JavaScript\">
window.location.replace('page.php');
</script>
</head>

<body>

Please enable Javascript and try again.
</body>

</html>

";

?>

 

So what should happen is the user is always redirected from page.php to gocheck.php, which sets the session variable $gocheck to 'yes' and directs back to page.php via Javascript. Because $gocheck is then equal to 'yes', page.php shouldn't direct back again tio gocheck.php.

 

This worked fine on my PC (using WAMP), but when I upload the files to the webhost, it seems to get stuck in an infinite redirect loop between page.php and gocheck.php. Also, if I echo $gocheck in page.php, it returns 'no', so it seems as if for some reason the session variable $gocheck is not being set properly by gocheck.php.

 

Could somebody please shed some light on this? Is there an error in my code? Is there something I need to change in php.ini on the webhost's server?

 

Thanks!

 

P.S. WAMP on my PC uses PHP v.5.3.0, but the webhost uses PHP v.5.2.12 - don't think this can be the problem though.

it is probably worth checking with your host that their server is working properly, i had a very similar experience with a live site not logging in and it turned out that the session log folder didnt have write permissions so it never held its values.  or something roughly along those lines.
