PHP Header重定向并在下一页回显会话？

Question

i am submitting a form and then using header redirect to take the user to a new page. how can i add a session to my header redirect to say once user has been redirected echo out a div within a session saying something like form submitted?

heres what i have tried to do but can not get it to work, can someone please point me in the right direction, thanks.

submit_form.php:

header("Location: ../index.php?success=$success");

index.php:

<?php echo $_SESSION['success']; ?>
    <?php $success= "<div> CONGRATULATIONS!!!!!</DIV>"; ?>

Answer 1

A session value is something stored in a session started with session_start().
What you have is a URL query parameter, which you can access with $_GET['success'].
