Hi everybody,

could you tell me why my session variable is not working?  I've attached part of the code im using.

File 1 (Creates a random number and displays it as a picture)
File 2 (Pull Session variable for validation)

The whole script works fine except for that session variable not being able to be passed.

<?php
session_start(); 
$_SESSION['rand'] = rand(10000, 99999);
$image = imagecreate(60, 30);
$bgColor = imagecolorallocate ($image, 255, 255, 102); 
$textColor = imagecolorallocate ($image, 0, 0, 0); 
imagestring ($image, 5, 5, 8, $_SESSION['rand'], $textColor); 
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); 
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); 

header("Cache-Control: no-store, no-cache, must-revalidate"); 
header("Cache-Control: post-check=0, pre-check=0", false); 

header("Pragma: no-cache"); 

header('Content-type: image/jpeg');
imagejpeg($image);
imagedestroy($image);
?>

I'm confused. In file1 you use $_SESSION['rand'] and in file2 you use $_SESSION['password']

There is no session information in common other than the session itself and sessions have no data unless you put it in there.

Hi

Place the attached code at the bottom of each page.
This will display the contents of $_SESSION

Please post the output.
debug($_SESSION);

function debug($array)
{
echo "<pre>";
print_r($array);
echo "</pre>";
}

Sorry, I just fixed that and it still doesn't work.  Can a hosting site disable that feature in PHP?  I've followed everything to the letter and it still doesn't work.  I've also put that code from  bitfreeze and it doesn't display anything.  I've also created a test.php which is called from the form and it has the following code

It should work no?  It should at least shwo the variable.
<?php
session_start();
echo ('here');
echo $_SESSION['rand'];
print_r($array);
echo "</pre>";

?>

Lets just check if it can save and retrieve a value.

<?php
session_start();

$_SESSION['testentry'] = "working";
echo $_SESSION['testentry'];

echo "</pre>";
print_r($_SESSION);
echo "</pre>";

?>

Thanks to you both, but it looks like the Host provider disabled the option...  Grrr.  Well it's all fixed and working now, thank you.
