Step-by-Step Guide to Integrating eGHL with Laravel

Setup Laravel Project:
Ensure you have a Laravel project set up. If not, you can create one using:

   composer create-project --prefer-dist laravel/laravel your_project_name

Install Required Packages:
Laravel comes with Guzzle, an HTTP client that can be used to make API requests. Ensure it is installed:

   composer require guzzlehttp/guzzle

Configure eGHL Settings:
Add your eGHL merchant details to the .env file:

   EGHL_MERCHANT_NAME=your_merchant_name
   EGHL_MERCHANT_ID=your_merchant_id
   EGHL_PASSWORD=your_password
   EGHL_PAYMENT_GATEWAY_URL=https://yourpaymentgatewayurl.com
   EGHL_RETURN_URL=https://yourdomain.com/payment/return
   EGHL_CALLBACK_URL=https://yourdomain.com/payment/callback

Create Routes:
Define routes for handling payment and response from eGHL in your routes/web.php:

   use App\Http\Controllers\PaymentController;

   Route::get('/payment', [PaymentController::class, 'index']);
   Route::post('/payment/process', [PaymentController::class, 'process']);
   Route::get('/payment/return', [PaymentController::class, 'return']);
   Route::post('/payment/callback', [PaymentController::class, 'callback']);

Create PaymentController:
Create a controller to handle the payment process:

   php artisan make:controller PaymentController

In PaymentController.php:

   namespace App\Http\Controllers;

   use Illuminate\Http\Request;
   use GuzzleHttp\Client;

   class PaymentController extends Controller
   {
       public function index()
       {
           return view('payment');
       }

       public function process(Request $request)
       {
           $merchantId = env('EGHL_MERCHANT_ID');
           $merchantName = env('EGHL_MERCHANT_NAME');
           $password = env('EGHL_PASSWORD');
           $amount = number_format($request->amount, 2);
           $orderId = 'INV' . time();
           $paymentDesc = $request->description;
           $currencyCode = 'MYR';
           $hash = sha1($merchantId.$password.$orderId.$amount.$currencyCode);

           $paymentData = [
               'MerchantID' => $merchantId,
               'ServiceID' => $merchantName,
               'PaymentID' => $orderId,
               'OrderNumber' => $orderId,
               'PaymentDesc' => $paymentDesc,
               'MerchantReturnURL' => env('EGHL_RETURN_URL'),
               'MerchantCallbackURL' => env('EGHL_CALLBACK_URL'),
               'Amount' => $amount,
               'CurrencyCode' => $currencyCode,
               'CustName' => $request->name,
               'CustEmail' => $request->email,
               'CustPhone' => $request->phone,
               'HashValue' => $hash,
           ];

           return view('process_payment', compact('paymentData'));
       }

       public function return(Request $request)
       {
           // Handle the return from eGHL
           $status = $request->TxnStatus;
           $orderId = $request->OrderNumber;
           $message = $request->TxnMessage;

           if ($status == '0') {
               // Payment successful
           } else {
               // Payment failed
           }

           return view('payment_return', compact('status', 'orderId', 'message'));
       }

       public function callback(Request $request)
       {
           // Handle the callback from eGHL
           // This will typically be used to update the payment status in your database
       }
   }

Create Payment View:
Create a view (resources/views/payment.blade.php) to handle the payment form:

   <form action="/payment/process" method="POST">
       @csrf
       <input type="text" name="amount" placeholder="Amount">
       <input type="text" name="description" placeholder="Description">
       <input type="text" name="name" placeholder="Name">
       <input type="email" name="email" placeholder="Email">
       <input type="text" name="phone" placeholder="Phone">
       <button type="submit">Pay Now</button>
   </form>

Create Process Payment View:
Create a view (resources/views/process_payment.blade.php) to handle the redirection to eGHL:

   <form id="eghl_form" method="POST" action="{{ env('EGHL_PAYMENT_GATEWAY_URL') }}">
       @foreach($paymentData as $key => $value)
           <input type="hidden" name="{{ $key }}" value="{{ $value }}">
       @endforeach
       <button type="submit">Proceed to Payment</button>
   </form>
   <script type="text/javascript">
       document.getElementById('eghl_form').submit();
   </script>

Handle Return and Callback:
Create views to handle the return and callback from eGHL. For example, resources/views/payment_return.blade.php:

   @if($status == '0')
       <p>Payment successful! Order ID: {{ $orderId }}</p>
   @else
       <p>Payment failed! Message: {{ $message }}</p>
   @endif

By following these steps, you should be able to integrate eGHL with your Laravel application. Make sure to test thoroughly in a sandbox environment provided by eGHL before going live.
