Keeping Vars through multiple submits

strategos · April 6, 2012

Hello, I am having an issue where PHP nulls the donation amount after multiple form submits. Here is a synopsis of what is happening.

1: User enters donation amount and clicks 'submit'

2: Is taken to a confirmation page where they must agree to terms

3: User fails to agree to the terms, the page is reloaded with an error message, and the donation amount is set to null

I want to make the donation amount display despite multiple confirm page reloads. How would I do this?

Here is the site to test it yourself. Ignore the steamid input and check "do not change my rank upon donation" to test.

Please note: If you use IE, the formatting is messed up, that is a problem I will look into later

Through the use of sessions or by passing the information through the header...

I have tried using a session var, but the result is the same.

Here is the code (I know its inefficient; its my first script)

<?php

session_start();

$amount = $_POST['amount'];

$cents = $_POST['coins'];

$agree = $_POST['confcheck'];

// Steam Donation System by Strategos

if (isset($_COOKIE['FormSubmitted']) && !isset($_POST['confirm'])){
die('
