In this example, I will give information about how to generate QR code in laravel. As per the current trend, many websites and applications provide features like login with a QR code, scanning QR codes, getting more information about products and websites, etc.
So, let's see how to generate QR code in laravel 6/7/8, laravel 7/8 QR code generate example, QR code generator in laravel 6/7/8, endroid QR code generator, how to dynamic QR code generator in laravel 6/7/8, laravel QR code generator with logo, QR code generator laravel 7.
So, I will implement a QR code in my project to give you a demo, there are many packages available to generate QR codes. So, in this example, I will use Endroid QR Code Generator. Also, you can generate a dynamic QR code generator in laravel 6/7.
Let's start QR code example In laravel 6/7 or laravel QR code generate an example with the code and implement the below code in your application.
Step 1: Install Laravel
Type the following command in the terminal to create a new project in your system.
composer create-project --prefer-dist laravel/laravel QRcodeStep 2: Install Endroid QRcode Package In Your Application
After installation of the project, you need to install Endroid QRcode Package
composer require endroid/qr-codeStep 3: Create Controller
Now, create a controller on this path app\Http\Controllers\QRController.php and add the below command.
<?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('websolutionstuff.com');
$qrCode->setSize(300);
$qrCode->setMargin(10);
$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(150, 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');
}
}Step 4 : Add Route
We need to add a route for generating QR codes and viewing files.
<?php
use Illuminate\Support\Facades\Route;
Route::get('qr_code/index','[email protected]')->name('qrcode.index');
Route::get('qr_code/create','[email protected]')->name('qrcode.create');Step 5 : Create Blade File
And after that, we need to create a blade file for viewing / generating, and downloading QR codes. So, add the below code in your index.blade.php file
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Qrcode - Websolutionstuff</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
</head>
<body>
<form class="text-center" action="{{route('qrcode.create')}}" method="get" accept-charset="utf-8">
<div class="row mt-5">
<div class="col-md-12">
<h2>Click on button to generate Qrcode - Websolutionstuff</h2>
<button class="btn btn-success" type="submit">Generate</button>
<a href="{{asset('qrcode.png')}}" class="btn btn-primary" download>Download</a><br>
<img class="img-thumbnail" src="{{asset('qrcode.png')}}" width="150" height="150" style="margin-top: 20px">
</div>
</div>
</form>
</body>
</html>You can customize this QRcode as per your requirements like changes in background colors, changes in foreground color, QRcode size, QRcode margin, etc...
To check this example run the below code in your browser.
http://localhost:8000/qr_code/indexAnd finally, you will get output like the below screen print.
