How to accept payments using Network Online – Payment gateway services?

Introduction

This example illustrates a basic way on integrating the Payment Gateway Service offered from Network Online.

Steps to Integrate the Network Online Payment Gateway

Step 1: Create a PHP file with the name “NetworkOnline.php” and add the following code.

<?php 
$enc = MCRYPT_RIJNDAEL_128;
$key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";//enter secret key
$mode = MCRYPT_MODE_CBC;
$iv = "0123456789abcdef";
$rand = substr(hash('sha512',uniqid(rand(), true)), 0, 5);
$merchantId='xxxxxxxxxxxxxxx';  //enter your merchant id
$text = "order-".$rand."|AED|1100|http://example.com/paymentmerchant.php?result=ok|http://example.com/paymentmerchant.php?result=ok|01|INTERNET|||||||rohit|p|alquoz| |Dubai|Dubai|123456|AE|abc@ymail.com||||||||||||||||||||||||FALSE|||||| ";


$text1 =$text; 

echo "Request Parameter in Plain Text: ".$text1;
echo '<br/>';
$size = mcrypt_get_block_size($enc, $mode);
$pad = $size - (strlen($text1) % $size);
$padtext = $text1 . str_repeat(chr($pad), $pad);

$crypt = mcrypt_encrypt($enc, base64_decode($key), $padtext, $mode, $iv);
echo 'After Encryption: '.$requestParameter=base64_encode($crypt);
echo '
<br/>';
$padtext = mcrypt_decrypt($enc, base64_decode($key), $crypt, $mode, $iv);

$pad = ord($padtext{strlen($padtext) - 1});
if ($pad > strlen($padtext)) return false;
if (strspn($padtext, $padtext{strlen($padtext) - 1}, strlen($padtext) - $pad) != $pad) {
$text = "Error";
}
$text = substr($padtext, 0, -1 * $pad);

echo '<br/>';

echo 'After Decryption: '.$text;

?>

<form action="https://uat.timesofmoney.com/direcpay/secure/PaymentTransactionServlet" method="post" id="networkonline_checkout" name="networkonline_checkout">
<input type="hidden" name="requestParameter" value="'.$merchantId.'|'.$requestParameter.'">
<input type="submit" value="Pay via networkonline" name="suba" id="sub">
</form>

Step 2: Create a PHP file with the name “paymentmerchant.php” and the following code.

This file will handle the response received from the payment gateway service provider.

<?php
Encrypted Response: '.$response = $_REQUEST['responseParameter'];
//$reponseParameters = explode("|",$_REQUEST['responseParameter']); 
$EncText=base64_decode($response);
$padtext = mcrypt_decrypt($enc, base64_decode($key), $EncText, $mode, $iv);

$pad = ord($padtext{strlen($padtext) - 1});
if ($pad > strlen($padtext)) return false;
if (strspn($padtext, $padtext{strlen($padtext) - 1}, strlen($padtext) - $pad) != $pad) {
	$text = "Error";
}
$text = substr($padtext, 0, -1 * $pad);

echo '
<br/>';
echo 'Decrypted Response: '.$text;

?>
