Question

I have a form that uses ajax to submit data to a mysql database, then sends the form on to PayPal.

However, after submitting, if I click the back button on my browser, change some fields, and then submit the form again, the mysql data isn’t updated, nor is a new entry created.

Here’s my Jquery:

$j(".submit").click(function() {
        var hasError = false;
        var order_id = $j('input[name="custom"]').val();
        var order_amount = $j('input[name="amount"]').val();
        var service_type = $j('input[name="item_name"]').val();
        var order_to = $j('input[name="to"]').val();
        var order_from = $j('input[name="from"]').val();
        var order_message = $j('textarea#message').val();
        if(hasError == false) {
            var dataString = 'order_id='+ order_id + '&order_amount=' + order_amount + '&service_type=' + service_type + '&order_to=' + order_to + '&order_from=' + order_from + '&order_message=' + order_message;
            $j.ajax({ type: "GET", cache: false, url: "/gc_process.php", data: dataString, success: function() { } });

        } else {

            return false;

        }
    });

Here’s what my PHP script looks like:

<?php

// Make a MySQL Connection
include('dbconnect.php');

// Get data
$order_id = $_GET['order_id'];
$amount = $_GET['order_amount'];
$type = $_GET['service_type'];
$to = $_GET['order_to'];
$from = $_GET['order_from'];
$message = $_GET['order_message'];

// Insert a row of information into the table
mysql_query("REPLACE INTO gift_certificates (order_id, order_type, amount, order_to, order_from, order_message) VALUES('$order_id', '$type', '$amount', '$to', '$from', '$message')");

mysql_close();

?>

Any ideas?

Turns out the problem is due to the fact that I am using iframes. I was able to fix the problem by making the page without iframes. Thanks for your help all!
