How to Generate QR Codes in Laravel 11 Example
Hello developers! In this guide, we'll see how to generate QR codes in laravel 11. Here, we'll use endroid QR code package in laravel 11. This library helps you generate QR codes in a jiffy. the trend of incorporating QR code functionality into websites and applications is gaining popularity.
Features like login with a QR code, scanning QR codes to access information about products and websites, and more are becoming increasingly common. QR codes offer convenience, efficiency, and enhanced user experiences.
We'll generate dynamic QR codes in laravel 11. we'll use Endroid QR Code package.
Laravel 11 Generate QR Code
In this step, we'll install the laravel 11 application using the following command.
composer create-project --prefer-dist laravel/laravel Laravel_11_QRCode
Now, we will install the Endroid QR Code package using the following command.
composer require endroid/qr-code
Then, we'll create a QRController.php file and in this file, we'll define the function and generate the QR code.
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'll define the 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
