QR (Quick Response) code is scannable black and white square box that stores data.

They are commonly used to store information, redirect users to a website, download files, payment, etc.

In this tutorial, I show how you can generate QR code using simple qrcode package in Laravel 8.

  3. Route
  4. Controller
  5. View

composer require simplesoftwareio/simple-qrcode

'providers' => [ .... .... .... SimpleSoftwareIO\QrCode\QrCodeServiceProvider::class, ];
  • Add the following 'QrCode' => SimpleSoftwareIO\QrCode\Facades\QrCode::class in 'aliases' –
'aliases' => [ .... .... .... 'QrCode' => SimpleSoftwareIO\QrCode\Facades\QrCode::class ];

3. Route

  • Define a routes –
    • / – Load index view.

Completed Code

<?php

use Illuminate\Support\Facades\Route;

Generate QR code with text and store in images/ folder for download. Load index view and pass $data.

$data['qrcode'] = QrCode::generate('Welcome to Makitweb'); // Store QR code QrCode::generate('Welcome to Makitweb', public_path('images/qrcode.svg') );

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use SimpleSoftwareIO\QrCode\Facades\QrCode;

class PageController extends Controller
{
    public function index(){
        // QR code with text
        $data['qrcode'] = QrCode::generate('Welcome to Makitweb');

        // Store QR code for download
        QrCode::generate('Welcome to Makitweb', public_path('images/qrcode.svg') );

        return view('index',$data);
    }

}

5. View

Create index.blade.php file in resources/views/ folder.
