Something really weird is going on with my database. I am using PHP to insert data into my database and I have been doing this for the past 2 years without any problems. When a customer makes a payment on my website, I store all of the data from that transaction in my database. Each transaction has a unique "transaction_id". When I insert the payment information into the database, all of the information is correctly inserted except for the "transaction_id". ALL transactions are given the "transaction_id" of "4294967295". So I did some testing. Here is what I did:
1) I echoed out the "transaction_id" to my screen to see what is would say. The results were that the "transaction_id" that was being echoed out was CORRECT. It was not the repeating "4294967295". However, when I look in my database, it shows "4294967295".
2) This time I decided to echo out the query to my web browser. The query was CORRECT. In the query, the CORRECT "transaction_id" was in the query. However, when I look in my database, it shows "4294967295".
I have 3 different pages where customers can make payments. ALL 3 pages started doing this on April 6th, 2012. None of those pages were modified at all. I have not modified those pages in over 2 years. Any help is greatly appreciated!
$query = "INSERT INTO payments (customer_id, transaction_id, invoice_number, authorization_code, subscription, subscription_id, avs_result, cvv_result, amount, full_tuition, payment_date, ip_address) VALUES ({$_SESSION['customer_id']}, {$_SESSION['transaction_id']}, {$_SESSION['invoice_number']}, '{$_SESSION['authorization_code']}', '{$_SESSION['subscription']}', {$_SESSION['subscription_id']}, '{$_SESSION['avs_result']}', '{$_SESSION['cvv_result']}', {$_SESSION['amount']}, {$_SESSION['full_tuition']}, '{$_SESSION['payment_date']}', '{$_SESSION['ip_address']}')" ;
$result = mysqli_query($dbc, $query) OR die ('<p>There was an error with the INSERT payments query.: ' . mysqli_error($dbc) . '<br />Query:' . $query . '</p>') ;
echo '<p>Transaction ' . $_SESSION['transaction_id'] . ' has been <font color="green">APPROVED</font> by the system.</p>' ;
echo '<br /><br />' ;
echo '<p>Below is a summary:</p>' ;
echo '<p>Transaction ID: ' . $_SESSION['transaction_id'] . '<br />
Payment Method: XXXX<br />
Amount: $' . $amount . '<br />
Customer Name: ' . $_SESSION['first_name'] . ' ' . $_SESSION['last_name'] . '<br />
</p>' ;
echo "<p>Note: Please do NOT click the browser's Back button to enter a new transaction.</p>" ;
echo $query ;
