[SOLVED] $_SESSION question.

[Reaper0167]

a member helped me out with displaying errors using $_SESSION['message']

on my login page everything works great... if the username is not registered an error displays on screen saying that it is not registered... But on my registration page when i user tries to register a name that is alreay registered, my error doesn't show up on that page. But it will display on my login page if i hit the back button on my browser. here is the code.

this is from the register script
<?php
if($count > 0)
{
session_start();
$_SESSION['message'] = "This username is already registered. Please try again.";
header("location: http://www.---------.com/registration.php");
exit();
}
?>

this is on my registration.php page where the form is
<?php
<?php if(isset($_SESSION['message'])){echo $_SESSION['message'];} ?>
?>

i have the exact same setup on my login page and all that works just fine....Am I only able to use a certain number of the echo $_SESSION['message'] statements or is there another problem. i am using header("location: http://www.-------.com/registration.php"); so shouldn't that be the one and only place it should display?

You need to call session_start() on the page where you wish to read the session data as well.
