IPG (Internet Payment Gateway) manager for Iran Banking System

This library uses MySQL database by default, and a predefined DB Schema. you should create the required tables in order to use this library. (BTW, you can implement your own DB logic using your own schema if you don't want to use the provided class in this library)

First, you need to extend each Gateway class you want to use, and provide authentication info for that Gateway
<?php
namespace Test;
use IPG\Gateways\Mellat\MellatIPG;
class MyMellat extends MellatIPG {
protected $terminalId = '123456789';
protected $userName = 'username';
protected $userPassword = 'P4$$w0rD';
}
Now, this class can be used with IPGManager as payment Gateway.
Then, IPGManager should be initialized
$man = new IPGManager(new MyMellat(), new IPGDatabase('username', 'password', 'db_name'));
Next step is to start the payment proccess
$res = $man->startPayment(time(), 10000, 'http://your-site.ir/callback.php');
Then the required data should be POSTed to the targetURL
if (!$res->isIsSuccessful()) {
echo 'FAILED';
exit();
}
$location = 'poster.php?data=' . json_encode($res->getData()) . '&url=' . $res->getTargetUrl();
header("Location: {$location}");
Here is a sample poster.php if you need one
<html>
<head>
<script>
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
var jsondata = getParameterByName("data");
var obj = JSON.parse(jsondata);
var form = document.createElement("form");
form.setAttribute("method", "POST");
form.setAttribute("target", "_self");
form.setAttribute("action", getParameterByName("url"));
var len = count = Object.keys(obj).length;
for (var key in obj) {
var hiddenField1 = document.createElement("input");
hiddenField1.setAttribute("name", key);
hiddenField1.setAttribute("value", obj[key]);
form.appendChild(hiddenField1);
}
form.submit();
document.body.removeChild(form);
</script>
</head>
<body></body>
</html>
Now, user is redirected to IPG website. after Payment completetion (or cancelation), the IPG will send the required data to the callback address you have provided.
In the callback file, you need to check that the payment is successful, if so deliver the product. you can reverse the payment if the product can not be delivered
<?php
require_once 'vendor/autoload.php';
use IPG\IPGDatabase;
use IPG\IPGManager;
$man = IPGManager::fromCallback($_REQUEST, new IPGDatabase('user', 'pass', 'db'));
$v = $man->validatePayment($_REQUEST);
if ($v->isValid()) {
// You should deliver the product now
// transactionId is the unique id that you provided in the startPayment method
// and is used to associate a payment transaction to a product order in your database
// you can use this id to find which order this payment is for, and deliver that product
$transactionId = $v->getTransactionId();
if (productDeliverIsSuccessful()) {
// Optionally you can settle the payment, if you dont it will settled automatically
$man->settle($v->getPayId(), $v->getReferenceId());
} else {
// if any error occured upon delivering the product
// you can reverse the payment, which will return the money to the customer
$man->reversal($v->getPayId(), $v->getReferenceId());
}
} else {
// you can get the last error after calling each method
$errorCode = $man->getErrorCode();
$errorMessage = $man->getErrorMessage();
}
// render the result page
if you want to use another IPG that is not implemented in this library, you should create a new class and extend it from IPG\Contract\AbstractIPG and provide the logic for that particular IPG.
You can extend the IPG\Contract\AbstractIPGDatabaseManager and provide the logic for database interaction.
Operation logging is activated by default, which will log each method call with its input and output. If you wish to turn this feature off, you should call the setLoggingEnabled method.
$man->setLoggingEnabled(false);
