In this article, we will see how to add a digital signature in pdf in laravel 9. Here, we will learn to add a digital signature certificate in pdf in laravel 8 and laravel 9. We will use elibyy/tcpdf-laravel package.
TCPDF is an open-source PHP library and the only PHP-based library that includes complete support for UTF-8 Unicode and right-to-left languages, including the bidirectional algorithm. Also, TCPDF is not supported in PHP 7.
So, let's see laravel 9 add a digital signature in pdf, add a digital signature to the pdf file, and add a digital signature certificate in pdf in laravel 7/8/9.
Step 1: Install Laravel 9
Step 2: Install TCPDF Package
Step 3: Configure TCPDF Package
Step 4: Add Routes
Step 5: Create Controller
Step 6: Create Blade File
In this step, we will install laravel 9 using the following command.
composer create-project --prefer-dist laravel/laravel laravel9_digital_signature The Laravel TCPDF service provider can be installed via composer by requiring the elibyy/tcpdf-laravel package in your project's composer.json. So, run the following command in the terminal.
composer require elibyy/tcpdf-laravelIf you are using a lower version of laravel like 5.5+ then need to add providers and aliases to the config.php file.
'providers' => [
//...
Elibyy\TCPDF\ServiceProvider::class,
]
//...
'aliases' => [
//...
'PDF' => Elibyy\TCPDF\Facades\TCPDF::class
]Now, we will add routes to the web.php file.
routes/web.php
<?php
use App\Http\Controllers\PDFController;
Route::get('/create/pdf', [PDFController::class, 'createPDF'])->name('createPDF');In this step, we will create a PDFController file using the following command.
php artisan make:controller PDFControllerapp/Http/Controllers/PDFController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use PDF;
class PDFController extends Controller
{
/**
* Where to redirect users after login.
*
* @var string
*/
public function createPDF(Request $request)
{
// set certificate file
$certificate = 'file://'.base_path().'/public/tcpdf.crt';
// set additional information in the signature
$info = array(
'Name' => 'Websolutionstuff',
'Location' => 'Office',
'Reason' => 'Websolutionstuff',
'ContactInfo' => 'http://www.websolutionstuff.com',
);
// set document signature
PDF::setSignature($certificate, $certificate, 'tcpdfdemo', '', 2, $info);
PDF::SetFont('helvetica', '', 12);
PDF::SetTitle('Websolutionstuff');
PDF::AddPage();
// print a line of text
$text = view('tcpdf');
// add view content
PDF::writeHTML($text, true, 0, true, 0);
// add image for signature
PDF::Image('tcpdf.png', 180, 60, 15, 15, 'PNG');
// define active area for signature appearance
PDF::setSignatureAppearance(180, 60, 15, 15);
// save pdf file
PDF::Output(public_path('hello_world.pdf'), 'F');
PDF::reset();
dd('pdf created');
}
} Note: check certificate location variable is prefixed 'file://'. otherwise, it will return the below error.
In this step, we will create a tcpdf.blade.php file. So, add the following code to that file.
