Payment Gateway Problem

[powerman]

Have a problem with setting up a payment gateway for my shopping card. I have manage to get almost all right except where the sum is going to be calculated and sent to the payment processor.

 

From the payment processor I got the following coding example:

 

<?php

$AgentID="???";

$Key="??????????";

 

$Description = "Description of item or service";

$SellerEmail = "seller@email.com";

$BuyerEmail = "buyer@email.com";

$Cost = "4"; //Cost of item or service

$ExtraCost = "0"; //Shipping

$OkUrl = "http://www.yoursite.com/verify.php";

$CancelUrl = "http://www.yoursite.com/error.php";

$RefNr = "123"; //Merchant reference number

$GuaranteeOffered = "1";

 

$MD5string = $SellerEmail . ":" . $Cost . ":" . $ExtraCost . ":" . $OkUrl . ":" . $GuaranteeOffered . $Key;

$MD5Hash = md5($MD5string);

?>

 

 

<form action="https://www.payson.se/merchant/default.aspx" method="post">

 

<input type="hidden" name="BuyerEmail" value="<?php echo $BuyerEmail ?>">

<input type="hidden" name="AgentID" value="<?php echo $AgentID ?>">

<input type="hidden" name="Description" value="<?php echo $Description ?>">

<input type="hidden" name="SellerEmail" value="<?php echo $SellerEmail ?>">

<input type="hidden" name="Cost" value="<?php echo $Cost ?>">

<input type="hidden" name="ExtraCost" value="<?php echo $ExtraCost ?>">

<input type="hidden" name="OkUrl" value="<?php echo $OkUrl ?>">

<input type="hidden" name="CancelUrl" value="<?php echo $CancelUrl ?>">

<input type="hidden" name="RefNr" value="<?php echo $RefNr ?>">

<input type="hidden" name="MD5" value="<?php echo $MD5Hash ?>">

<input type="hidden" name="GuaranteeOffered" value="<?php echo $GuaranteeOffered ?>">

 

<input type="submit" value="Send request">

</form>

 

Here is my code:

<form method="post" action="https://www.payson.se/testagent/default.aspx" name="gateway_payson" id="gateway_payson">

<input type="hidden" name="SellerEmail" value="<?php echo get_option('gateway_payson_email'); ?>"/>

<input type="hidden" name="AgentId" value="<?php echo get_option('gateway_payson_agentid'); ?>"/>

<input type="hidden" name="GuaranteeOffered" value="<?php echo get_option('gateway_payson_guaranteeoffered'); ?>"/>

<input type="hidden" name="OkUrl" value="<?php echo get_option('gateway_payson_callback'); ?>"/>

<input type="hidden" name="RefNr" value="<?php echo $data['orderid']; ?>"/>

<input type="hidden" name="Description" value="<?php echo strip_tags($data['description']); ?>"/>

<input type="hidden" name="Cost" value="<?php echo $data['price']['total']; ?>"/>

<input type="hidden" name="ExtraCost" value="0">

<input type="hidden" name="MD5" value="<?php echo get_option('gateway_payson_receiver');('SellerEmail'); ('OkUrl'); ('GuaranteeOffered'); ('ExtraCost'); ('Cost'); ?>"/>

 

 

 

 

<input type="hidden" name="opt_name" value="<?php echo get_user_meta($userdata->ID, 'first_name', true).' '.get_user_meta($userdata->ID, 'last_name', true); ?>"/>

 

<input type="hidden" name="BuyerEmail" value="<?php echo $userdata->user_email; ?>"/>

<input type="hidden" name="opt_mobile" value="<?php echo $ADD[5]; ?>"/>

 

<?php echo MakePayButton('javascript:document.gateway_payson.submit();'); ?>

</form>

 

<?php }

 

function payson_new_gateway($gateways){

 

$nId = count($gateways)+1;

 

$gateways[$nId]['name'] = "Payson Gateway"; // STRING - NAME OF YOUR GATEWAY

return $gateways;

 

}

function gateway_payson_callback($orderID){

 

global $wpdb, $PPTPayment;

 

//error_reporting(E_ALL ^ E_NOTICE);

$email = get_option('gateway_payson_email'); // <------ change to your email address!!!

$header = "";

$emailtext = "EMAIL";

// Read the post from OKPAY and add 'ok_verify'

$req = 'paysbuy_verify=true';

 

foreach ($_POST as $key => $value){

$emailtext .= $key . " = " .$value ."\n\n";

}

mail($email, "Paysbuy-VERIFIED ", $emailtext . "\n\n" . $req . "\n\n");

 

 

$result = $_POST["result"];

$result = substr($result, 0, 2);

$apCode = $_POST["apCode"];

$amt = $_POST["amt"];

$fee = $_POST["fee"];

$method = $_POST["method"];

$confirm_cs = strtolower(trim($_POST["confirm_cs"]));

/* status result

00=Success

99=Fail

02=Process

*/

if ($result == "00") {

if ($method == "06") {

if ($confirm_cs == "true") {

$PPTPayment->UpdateOrderStatus(5, $orderID);

echo "Success";

return "thankyou";

} else if ($confirm_cs == "false") {

echo "Fail";

} else {

echo "Process";

}

} else {

$PPTPayment->UpdateOrderStatus(5, $orderID);

echo "Success";

return "thankyou";

 

}

} else if ($result == "99") {

echo "Fail";

} else if ($result == "02") {

echo "Process";

} else {

echo "Error";

}

 

 

 

 

 

 

 

 

return ""; // RETURN FOR OTHER PAYMENT PROCESSING

 

}

 

add_action('premiumpress_callback_paymentstatus','gateway_payson_callback');

 

?>

 

So my problem is how to get this part to work

 

$MD5string = $SellerEmail . ":" . $Cost . ":" . $ExtraCost . ":" . $OkUrl . ":" . $GuaranteeOffered . $Key;

$MD5Hash = md5($MD5string);

 

Any suggestions?

That looks like valid syntax to me. Are your variables set as what they are supposed to be? If so, perhaps your problem is related to something else.

What do you mean by "work"?  What are you trying to accomplish?
