Note : Skip step 1 and 2 if you already have application.

Create New Application

First, open terminal and create new Laravel application using below command :

Database Configuration

Let's configure database for our application. If you have don't have any database then create a new one. After creating database open .env file from root directory of your project. if .env file is missing from project then copy content from .env.example and create file. .env file defines many common environment variables

Install QR Code Package

Let's head back to terminal at root directory of project and enter below command :

composer require simplesoftwareio/simple-qrcode

It will take some time to install simplesoftwareio/simple-qrcode package. We will use this package to generate QR codes.

Register QR Code Service

Now, we have installed our package but in order to use it, we need to register it to our application. you can do that by registering it into config\app.php file. so open the file and update the providers and alias array with the given below services.



    return [

        'providers' => [

        'aliases' => [
            'QrCode' => SimpleSoftwareIO\QrCode\Facades\QrCode::class,

Building New Controller for QR Code

Let's create a controller which will handle, user request and pass user input to view. For creating new controller enter below command into your terminal :

php artisan make:controller QrCodeController

Now let's modify our controller which will take user input and pass it to view. For that make following changes into your controller :



namespace App\Http\Controllers;

use Illuminate\Http\Request;

class QrCodeController extends Controller
    public function showQrCode(Request $request)
        $user_name = $request->input('name');
        return view('qr_code', compact('user_name'));

Adding QR Code Related Routes

Let's create route which will interacts with the QrCodeController and provides a link to view.



use App\Http\Controllers\QrCodeController;
use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return view('welcome');

Route::post('/show-qr-code',[QrCodeController::class, 'showQrCode'])->name('');

Creating Blade Files or Views

Here, we are planning to display QR Code from user input so we need to 2 views. First will take user input like name and second will display QR code for that name.

We will use default welcome view to get user input. In this blade file, we will remove all content and just add simple form with one input.


Let's create new blade file for display qr codes to user. Here, we will bootstrap for styling output.
