<?php
 
 
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
 
 
class CreateEventRegisterTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('event_registration', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('mobile_no');
            $table->text('desc');
            $table->tinyInteger('status')->default(0);
            $table->integer('fee');
            $table->string('order_id');
            $table->string('transaction_id')->default(0);
            $table->timestamps();
        });
    }
 
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop("event_registration");
    }
}
 

Now run the below migration command

1
2
3
 
php artisan migrate
 

Step 5:- Now create the event registration model file, So let’s create new file in app/EventRegistration.php

namespace App;
 
 
use Illuminate\Database\Eloquent\Model;
 
 
class EventRegistration extends Model
{
    protected $table = 'event_registration';
 
 
    protected $fillable = ['name','mobile_no','desc','status','fee','order_id','transaction_id'];
 
 
    /*
status : 0 => progress, 1 => Fail, 2 => Successful
    */
}
 

Step 6:- Now create the web and API routes in web.php and api.php

web.php

<?php
 
 
/*

|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
 
 
Route::get('eventRegistration', 'OrderController@register');
Route::post('paytmPayment', 'OrderController@order');
 

api.php

*/
 
 
Route::post('payment/status', 'OrderController@paymentCallback');

<?php
 
 
namespace App\Http\Controllers;
 
 
use PaytmWallet;
use Illuminate\Http\Request;
use App\EventRegistration;
 
 
class OrderController extends Controller
{
 
 
    /**
     * Redirect the user to the Payment Gateway.
     *
     * @return Response
     */
    public function register()
    {
        return view('payment_form');
    }
 
 
    /**
     * Redirect the user to the Payment Gateway.
     *
     * @return Response
     */
    public function order(Request $request)
    {
 
 
        $this->validate($request, [
            'name' => 'required',
            'mobile_no' => 'required|numeric|digits:10|unique:event_registration,mobile_no',
            'desc' => 'required',
        ]);
 
 
        $input = $request->all();
        $input['order_id'] = $request->mobile_no.rand(1,100);
        $input['fee'] = 50;
 
 
        EventRegistration::create($input);
 
 
        $payment = PaytmWallet::with('receive');
        $payment->prepare([
          'order' => $input['order_id'],
          'user' => 'your paytm user',
          'mobile_number' => 'your paytm number',
          'email' => 'your paytm email',
          'amount' => $input['fee'],
          'callback_url' => url('api/payment/status')
        ]);
        return $payment->receive();
    }
 
 
    /**
     * Obtain the payment information.
     *
     * @return Object
     */
    public function paymentCallback()
    {
        $transaction = PaytmWallet::with('receive');
 
 
        $response = $transaction->response();
        $order_id = $transaction->getOrderId();
 
 
        if($transaction->isSuccessful()){
          EventRegistration::where('order_id',$order_id)->update(['status'=>2, 'transaction_id'=>$transaction->getTransactionId()]);
 
 
          dd('Payment Successfully Paid.');
        }else if($transaction->isFailed()){
          EventRegistration::where('order_id',$order_id)->update(['status'=>1, 'transaction_id'=>$transaction->getTransactionId()]);
          dd('Payment Failed.');
        }
    }    
}
 

Step 8:- Now create the view file with payment form payment_form.blade.php
