Install laravel 6 Fresh Project

We need to install laravel 6 fresh application using below command, Open your command prompt and run the below command :

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

After successfully install laravel 6 Application, Go to your project .env file and set up database credential and move next step.

Configuration in .env

In this step, we will set database credential in .env file. Let’s open .env file.

 DB_CONNECTION=mysql 
 DB_HOST=127.0.0.1 
 DB_PORT=3306 
 DB_DATABASE=your database name here
 DB_USERNAME=database username here
 DB_PASSWORD=database password here

Install Anandsiddharth paytm package

Use the below command and install the package :

composer require anandsiddharth/laravel-paytm-wallet

After successfully install the package, we need to register the provider and alias. Go to the app/config/app.php and put the below lines here :

'providers' => [
     // Other service providers…
     Anand\LaravelPaytmWallet\PaytmWalletServiceProvider::class,
 ],
 'aliases' => [
     // Other aliases
     'PaytmWallet' => Anand\LaravelPaytmWallet\Facades\PaytmWallet::class,
 ],

We need to set a paytm credential like below. Go to the app/config/services.php and set the paytm credential.

'paytm-wallet' => [
     'env' => 'production', // values : (local | production)
     'merchant_id' => 'YOUR_MERCHANT_ID',
     'merchant_key' => 'YOUR_MERCHANT_KEY',
     'merchant_website' => 'YOUR_WEBSITE',
     'channel' => 'YOUR_CHANNEL',
     'industry_type' => 'YOUR_INDUSTRY_TYPE',
 ],

All the credentials mentioned are provided by Paytm after signing up as a merchant.

Generate Migration and Create Model

Now we will Create table name notes and it’s migration file. use the below command :

php artisan make:model Event -m

Its command will create one model name Event and also create one migration file for the events table. After successfully run the command go to database/migrations file and put the below here :

<?php 
  
use Illuminate\Support\Facades\Schema; 
use Illuminate\Database\Schema\Blueprint; 
use Illuminate\Database\Migrations\Migration; 
   
class CreateEventsTable extends Migration 
{ 
    /** 
     * Run the migrations. 
     * 
     * @return void 
     */ 
    public function up() 
    { 
        Schema::create('products', function (Blueprint $table) { 
            $table->increments('id'); 
            $table->string('name');
            $table->string('mobile_number');
            $table->integer('amount');
            $table->string('order_id');
            $table->string('status')->default('pending');
            $table->string('transaction_id')->default(0);
            $table->timestamps(); 
        }); 
    } 
   
    /** 
     * Reverse the migrations. 
     * 
     * @return void 
     */ 
    public function down() 
    { 
        Schema::dropIfExists('events'); 
    } 
} 

Next, migrate the table using the below command.

php artisan migrate

Now, add the fillable property inside the Event.php file.

<?php
 
namespace App;
 
use Illuminate\Database\Eloquent\Model;
 
class Note extends Model
{
  protected $fillable = ['name','mobile_number',
                         'amount','status',
                       'order_id','transaction_id'];
}

Make Route

<?php 

Route::get('event', '[email protected]');
Route::post('payment', '[email protected]');
Route::post('payment/status', '[email protected]');

Create Controller

Create the controller name EventController using the below command.

php artisan make:controller EventController

Go to app/HTTP/Controller/EventController and put the below code :

<?php


namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Event;
use PaytmWallet;


class EventController extends Controller
{


    /**
     * Redirect the user to the Payment Gateway.
     *
     * @return Response
     */
    public function bookEvent()
    {
        return view('book_event');
    }


    /**
     * Redirect the user to the Payment Gateway.
     *
     * @return Response
     */
    public function eventOrderGen(Request $request)
    {
     $this->validate($request, [
          'name' => 'required',
          'mobile_no' =>'required|numeric|digits:10|unique:events,mobile_number',
        ]);

        $input = $request->all();
        $input['order_id'] = rand(1111,9999);
        $input['amount'] = 50;

        Event::insert($input);

        $payment = PaytmWallet::with('receive');
        $payment->prepare([
          'order' => $input['order_id'],
          'user' => 'user id',
          'mobile_number' => $request->mobile_number,
          'email' => $request->email,
          'amount' => $input['amount'],
          'callback_url' => url('payment/status')
        ]);
        return $payment->receive();
    }

    /**
     * Obtain the payment information.
     *
     * @return Object
     */
    public function paymentCallback()
    {
        $transaction = PaytmWallet::with('receive');

        $response = $transaction->response();

        if($transaction->isSuccessful()){
          Event::where('order_id',$response['ORDERID'])->update(['status'=>'success', 'payment_id'=>$response['TXNID']]);

          dd('Payment Successfully Credited.');

        }else if($transaction->isFailed()){
          Event::where('order_id',$order_id)->update(['status'=>'failed', 'payment_id'=>$response['TXNID']]);
          dd('Payment Failed. Try again lator');
        }
    }    
}

Create Blade View file

We need to create blade views file, Go to app/resources/views/ and create one file name event.blade.php :

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <meta name="csrf-token" content="{{ csrf_token() }}">

<div class="container">

@if ($errors->any())
    <div class="alert alert-danger">
        <strong>Whoops!</strong> Something went wrong<br>
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
   
<form action="{{ url('payment') }}" method="POST" name="paytm">
    {{ csrf_field() }}
  
     <div class="row">
        <div class="col-md-12">
            <div class="form-group">

                <input type="text" name="name" class="form-control" placeholder="Enter Name">

                <input type="text" name="email" class="form-control" placeholder="Enter Email id">
            </div>
        </div>
        <div class="col-md-12">
            <div class="form-group">
                <strong>Event Fees</strong>
                <input type="text" name="amount" class="form-control" placeholder="" value="100" readonly="">
            </div>

Start Development Server

In this step, we will use the PHP artisan serve command. It will start your server locally

php artisan serve

If you want to run the project diffrent port so use this below command 

php artisan serve --port=8080  

Now we are ready to run our example so run bellow command to quick run.

http://localhost:8000/event

Or direct hit in your browser

http://localhost/blog/public/event
