How to get the referring filename from a request in PHP

Question

I'm building the finishing touches on the registration aspect of my web application and am scratching my head on how I'm going to display a "success" message.

I've decided that I will redirect using:

header("Location: account.php", true, 303);

Once I've done that, I've decided to check the referring filename (and GET variable) to make sure it came from "account.php?action=processregister".

I'm wondering, how might I write code to retrieve the filename (and variables) that processed the redirect?

If you require more information, such as code, feel free to ask.

Answer 1

To get the refferer $_SERVER['HTTP_REFERER']; from here http://php.net/manual/en/reserved.variables.server.php

For your question, i think you need to store some data in $_SESSION.

For example, $_SESSION['flash-message'] = 'Registration done successefull!';
