How to Write Text on Existing PDF File in Laravel

Introduction: In this tutorial, we will explore the process of write text on an existing PDF file in Laravel framework. Manipulating PDF files is a common requirement in web applications, and Laravel provides convenient tools for accomplishing this task. By the end of this guide, you will have a clear understanding of how to integrate text into an existing PDF file seamlessly.

Prerequisites: Before we begin, make sure you have the following prerequisites installed:

  1. Laravel: Ensure that you have a Laravel application up and running. You can install Laravel using Composer by running the following command:
composer create-project --prefer-dist laravel/laravel your-project-name
  1. Composer: Make sure Composer is installed on your system. If not, you can download it from https://getcomposer.org/.
  2. PDF Manipulation Library: Install a PDF manipulation library to assist in writing text on the PDF file. In this tutorial, we will use the popular library called “barryvdh/laravel-dompdf.” Install it using Composer:
composer require barryvdh/laravel-dompdf

Once these prerequisites are in place, we can proceed with the implementation.

Step 1: Configure Laravel-Dompdf:

Open your Laravel project and navigate to the config/app.php file. Add the following service provider and facade:

'providers' => [
    // ...
    Barryvdh\DomPDF\ServiceProvider::class,
],

'aliases' => [
    // ...
    'PDF' => Barryvdh\DomPDF\Facade::class,
],

Run the following command to publish the configuration file:

php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"

Step 2: Create a Controller:

Generate a new controller by running the following command:

php artisan make:controller PdfController

Open the newly created PdfController.php file in the app/Http/Controllers directory.

Step 3: Write Code to Add Text to PDF:

Add the following code to your PdfController.php file to create a simple PDF with text:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use PDF;

class PdfController extends Controller
{
    public function writeTextOnPdf()
    {
        $pdf = PDF::loadView('pdf.template', ['text' => 'Hello, Laravel PDF!']);

        return $pdf->stream('output.pdf');
    }
}

This code defines a writeTextOnPdf method that generates a PDF using a Blade view named pdf.template and passes the text “Hello, Laravel PDF!” as a variable.

Step 4: Create Blade View:

Create a new Blade view file named template.blade.php in the resources/views/pdf directory with the following content:

<!DOCTYPE html>
<html>
<head>
    <title>Laravel PDF Tutorial</title>
</head>
<body>
    <h1>{{ $text }}</h1>
</body>
</html>

Step 5: Define a Route:

Open the web.php file in the routes directory and add a route to the writeTextOnPdf method:

use App\Http\Controllers\PdfController;

Route::get('/write-text-on-pdf', [PdfController::class, 'writeTextOnPdf']);

Step 6: Test the Implementation:

Run your Laravel development server using the following command:

php artisan serve

Visit http://localhost:8000/write-text-on-pdf in your browser to see the PDF with the added text.

Conclusion:

Congratulations! You have successfully learned how to write text on an existing PDF file in Laravel using the barryvdh/laravel-dompdf library. Feel free to customize the code to suit your specific requirements and explore additional features offered by the library for more advanced PDF manipulations. Happy coding!
