Question

I want to integrate the payment partal without displaying the MasterCard interface to user the will only fill their information on my web

I am trying to implement CommWeb on my PHP site using curl. It isn't working. I am getting following error message:
if ($_SERVER["REQUEST_METHOD"] == "GET") {
if (!isset($_GET['id']) || !isset($_GET['motif']) || !isset($_GET['code'])){
die("Invalid request");
}
$amount = 10000;
$id = 2;
$motif = 'save';
$action_code = 'ookkk';
$orderInfo = 'fhhsd'.$id;
$MerchTxnRef = $orderInfo.'-'.generateMerchTxnRef();
$accountData = array(
'merchant_id' => 'TESTID', // for test card
'access_code' => '77867878', // for test card
'secret' => 'TYUJHGFDFGHJ87654567GFDFGHGF' // for test card
);
$currency_str = "USD";
$mult = 100;
$queryData = array(
'vpc_AccessCode' => $accountData['access_code'],
'vpc_Merchant' => $accountData['merchant_id'],
'vpc_Amount' => 1000000, // Multiplying by 100 to convert to the smallest unit
'vpc_OrderInfo' => $orderInfo,
'vpc_MerchTxnRef' => $MerchTxnRef,
'vpc_Command' => 'pay',
'vpc_Currency' => $currency_str,
'vpc_Locale' => 'en',
'vpc_Version' => 2,
'vpc_ReturnURL' => ('http://theeventsfactory.biz/the_events_factory/logics/payment_return.php?id='.$id.'&motif='.$motif.'&code='.$action_code),
'vpc_SecureHashType' => 'SHA256',
'vpc_CardNum' => '5123456789012346',
'vpc_CardExp' => '0521',
'vpc_CardSecurityCode'=> '123'
);
// Add secure secret after hashing
// $queryData['vpc_SecureHash'] = generateSecureHash($accountData['secret'], $queryData);
// $migsUrl = 'https://migs.mastercard.com.au/vpcpay?'.http_build_query($queryData);
$ch = curl_init("https://migs.mastercard.com.au/vpcdps");
curl_setopt_array($ch, array(
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $queryData,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HEADER => false
));
$response = curl_exec($ch);
print_r($response);
}
function generateMerchTxnRef() {
$txnRef = rand(9, 9999999999999999);
// Saved in the database associated with the order id
return $txnRef;
}
function generateSecureHash($secret, array $params) {
$secureHash = "";
// Sorting params first based on the keys
ksort($params);
foreach ($params as $key => $value)
{
// Check if key equals to vpc_SecureHash or vpc_SecureHashType to discard it
if(in_array($key, array('vpc_SecureHash', 'vpc_SecureHashType'))) continue;
// If key either starts with vpc_ or user_
if(substr( $key, 0, 4 ) === "vpc_" || substr($key, 0, 5) === "user_") {
$secureHash .= $key."=".$value."&";
}
}
// Remove the last `&` character from string
$secureHash = rtrim($secureHash, "&");
//
return strtoupper(hash_hmac('sha256', $secureHash, pack('H*', $secret)));
}
This is the response i am receiving
vpc_Amount=0&vpc_BatchNo=0&vpc_Locale=en&vpc_Message=Required+field+vpc_Merchant+was+not+present+in+the+request&vpc_TransactionNo=0&vpc_TxnResponseCode=7
How will i solve this problem

You need to convert the array to a url encoded string with http_build_query
after setting the queryData array, add
$queryData_string = http_build_query($queryData);
Then the curlpost would be set to that
CURLOPT_POSTFIELDS => $queryData_string,
