QR codes have evolved into an indispensable tool for connecting the physical and digital worlds, and incorporating them into PDF documents can be extremely beneficial.

We’ll walk you through the process of adding QR codes to PDF documents in Laravel 10 using the DomPDF module in this article. This tool can be used to include contact information, links, or event details in your PDFs, among other things.

QR codes allow users to quickly access digital content by scanning the code with a smartphone or QR code reader. This function is useful for quickly and easily exchanging URLs, contact information, event details, and other information.

Let’s get started.

What is QR Code?

A QR code, which stands for “Quick Response code” is a two-dimensional matrix barcode that was invented in Japan to track automotive parts. Because of their adaptability and capacity to contain a substantial amount of data, QR codes have now become immensely popular and are utilised for a range of applications.

Example,

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Installation of Laravel DomPDF and QR Code Package

Here, we will install a pdf and qrcode package to laravel application.

Open project terminal and run this command,

DomPDF Package

composer require barryvdh/laravel-dompdf

QR Code Package

composer require simplesoftwareio/simple-qrcode

Setup PDF Controller

Back to project terminal and run this command into it,

php artisan make:controller PDFController

It will create a PDFController.php file inside /app/Http/Controllers folder.

Open file and write this code into it,

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use SimpleSoftwareIO\QrCode\Facades\QrCode;
use PDF;
    
class PDFController extends Controller
{
    public function generatePDF()
    {
        $qrcode = base64_encode(QrCode::format('svg')->size(200)->errorCorrection('H')->generate('string'));

        $data = [
            'title' => 'Welcome to Online Web Tutor',
            'qrcode' => $qrcode
        ];  
              
        $pdf = PDF::loadView('my-pdf', $data);
  
        return $pdf->download('onlinewebtutor.pdf');
    }
}

Create Blade Template

Create a file named as my-pdf.blade.php inside /resources/views folder.

This template file will be the layout for pdf file with qr code image in it.

Open file and write this code into it,

<!DOCTYPE html>
<html>

<head>
    <title>Laravel 10 How to Add QR Code in PDF Using DomPDF</title>
</head>

<body>

    <div>
        <h1>Laravel PDF with QR Code Example</h1>

        <p>

        </p>

        <img src="data:image/png;base64,{{ $qrcode }}">

    </div>

</body>

</html>
