Barcodes are used in document management, inventory monitoring, and a variety of other applications. In this tutorial, you’ll learn how to add a barcode to PDF documents in Laravel 10 using the famous DomPDF package.

Barcodes make data entry and retrieval more efficient and accurate. They are used in inventory management, shipping labels, event tickets, and a variety of other applications. By including barcodes into your PDFs, you improve their usability and automation.

Let’s get started.

What is Barcode?

A barcode is a machine-readable visual, binary representation of data. It is made up of a succession of parallel lines, bars, or dots with variable widths and spacings that are commonly used on labels, items, or packaging.

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 Barcode Package

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

Open project terminal and run this command,

DomPDF Package

composer require barryvdh/laravel-dompdf

Barcode Package

composer require picqer/php-barcode-generator

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 Picqer\Barcode\BarcodeGeneratorPNG;
use PDF;
    
class PDFController extends Controller
{
    public function generatePDF()
    {
        $generator = new BarcodeGeneratorPNG();
        $barcode = base64_encode($generator->getBarcode('081231723897', $generator::TYPE_CODE_128));
        $data = [
            'title' => 'Welcome to Online Web Tutor',
            'barcode' => $barcode
        ]; 
              
        $pdf = PDF::loadView('my-pdf', $data);
  
        return $pdf->download('onlinewebtutor.pdf');
    }
}

Open file and write this code into it,

<!DOCTYPE html>
<html>

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

<body>

    <div>
