As per the current trend, many websites and applications provide features like login with QR code, scan QR code, and get more information about products and websites, etc. we will generate dynamic QR codes in laravel 9. There are many packages available to generate QR codes. we will use Endroid QR Code Generator to create QR Code.
So, let's see how to generate QR code in laravel 9, laravel 9 QR code generator.
Step 1: Install Laravel 9 for QR Code
Step 2: Install Endroid QR Code Package
Step 3: Create Controller
Step 4: Add Route
Step 5: Create Blade File
In this step, we will install the laravel 9 application using the following command.
composer create-project --prefer-dist laravel/laravel Laravel_9_QRCode_Generator
In this step, we will install the Endroid QR Code package using the following command.
composer require endroid/qr-code
Now, we will create a QRController.php file.
app\Http\Controllers\QRController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Endroid\QrCode\QrCode;
use Endroid\QrCode\ErrorCorrectionLevel;
use Endroid\QrCode\LabelAlignment;
class QRController extends Controller
{
public function index()
{
return view('qrcode.index');
}
public function create()
{
$qrCode = new QrCode('techsolutionstuff.com');
$qrCode->setSize(300);
$qrCode->setMargin(20);
$qrCode->setEncoding('UTF-8');
$qrCode->setWriterByName('png');
$qrCode->setErrorCorrectionLevel(ErrorCorrectionLevel::HIGH());
$qrCode->setForegroundColor(['r' => 0, 'g' => 0, 'b' => 0, 'a' => 0]);
$qrCode->setBackgroundColor(['r' => 255, 'g' => 255, 'b' => 255, 'a' => 0]);
$qrCode->setLogoSize(200, 200);
$qrCode->setValidateResult(false);
$qrCode->setRoundBlockSize(true);
$qrCode->setWriterOptions(['exclude_xml_declaration' => true]);
header('Content-Type: '.$qrCode->getContentType());
$qrCode->writeFile(public_path('/qrcode.png'));
return redirect()->route('qrcode.index');
}
}
In this step, we will add routes in the web.php file.
routes/web.php
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\QRController;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| 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('/', function () {
return view('welcome');
});
Route::get('qr_code/index',[QRController::class,'index'])->name('qrcode.index');
Route::get('qr_code/create',[QRController::class,'create'])->name('qrcode.create');
Now, we will create a blade file for viewing.
index.blade.php

<html>
<head>
<meta charset="utf-8">
