Realex Payment Module


MrJoesph

Recommended Posts

Hi can anyone help with a response script for Realex payments?

 

 

I copied the code from checkout_process.php and pasted it into where it should go. I have it working almost perfectly in test mode, the payment goes through to Realex successfully and the oscommerce database gets updates and the customer is emailed. Except when I enter a declined card (for testing purposes), I get no result, just a blank page. Here is the script (a template provided by Realex). Realex say you must add the part about updating/emailing yourself. I'm not a PHP programmer so I'm a bit out of my depth here.

 

<html>

<head>

<title>Response Script</title>

 

<?

 

/*

Note:The below code is used to grab the fields Realex Payments POSTs back

to this script after a card has been authorised. Realex Payments need

to know the full URL of this script in order to POST the data back to this

script. Please inform Realex Payments of this URL if they do not have it

already.

 

Look at the Realex Documentation to view all hidden fields Realex POSTs back

for a card transaction.

*/

 

 

 

$timestamp = $_POST['TIMESTAMP'];

$result = $_POST['RESULT'];

$orderid = $_POST['ORDER_ID'];

$message = $_POST['MESSAGE'];

$authcode = $_POST['AUTHCODE'];

$pasref = $_POST['PASREF'];

$realexmd5 = $_POST['MD5HASH'];

 

// -------------------------------------------------------------

// Replace these with the values you receive from Realex Payments.If you have not yet received these values please contact us.

$merchantid = "*******";

$secret = "*******";

 

//---------------------------------------------------------------

//Below is the code for creating the digital signature using the md5 algorithm.

//This digital siganture should correspond to the

//one Realex Payments POSTs back to this script and can therefore be used to verify the message Realex sends back.

 

$tmp = "$timestamp.$merchantid.$orderid.$result.$message.$pasref.$authcode";

$md5hash = md5($tmp);

$tmp = "$md5hash.$secret";

$md5hash = md5($tmp);

 

//Check to see if hashes match or not

if ($md5hash != $realexmd5) {

echo "hashes don't match - response not authenticated!";

}

 

/* --------------------------------------------------------------

send yourself an email or send the customer an email or update a database or whatever you want to do here.

Hi MrJoesph, I know this was a very long time ago that you were having this issue, and I am wondering if you managed to resolve the issue that you were having. it appears that I am having the same issue, I get a blank screen after putting in my credit card details. In the address that I am sent back to I can see the error: http://www.x.com/index.php?main_page=checkout_payment&payment_error=realex&error=Hashes%20don't%20match%20-%20response%20not%20authenticated!

 

Do you know was this the same issue that you were getting and by any chance do you remember what you did to fix this issue.

 

Any help that you may be able to give would be really appreciative.

Many thanks

Alex
