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 = "
[email protected]";
$BuyerEmail = "
[email protected]";
$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 }

$nId = count($gateways)+1;
$gateways[$nId]['name'] = "Payson Gateway"; // STRING - NAME OF YOUR GATEWAY

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?
