PHP - Pass POST variables with header()?

Question

I\'m trying to use the header() function to create a redirect. I would like to display an error message. Currently I\'m sending the message as a parameter through the URL,

Dan, You could start and store a session in PHP then save the message as a session variable. This saves you from having to transfer the message in an HTTP request.

Manipulating Sessions

//Start the session
session_start();

//Dump your POST variables
$_SESSION['POST'] = $_POST;

//Redirect the user to the next page
header("Location: bar.php");

Now, within bar.php you can access those POST variables by re-initiating the session.

//Start the session
session_start();

//Access your POST variables
$temp = $_SESSION['POST'];

//Unset the useless session variable
unset($_SESSION['POST']);
