In this post, we will show you how to generate PDF in Codeigniter 4. As we know PDF is used to read any information in the form of a document. And a PDF document always reveals information for other documents such as applications, user manuals, e-books. The PDF file is always used via the .pdf file extension and the portable document format.
If you are also a Codeigniter developer and you want to create a PDF file from the HTML view template using the domPDF library in Codeigniter 4. Then this post will prove to be beneficial for you.
Install Codeigniter Application:
At this point, we are now going to install the CodeIgniter 4 application using the composer package.
composer create-project codeigniter4/appstarterHere we have changed to Codeigniter-PDF-Example, now you rename the Codeigniter folder.
Then go inside the project folder.
cd codeigniter-pdf-exampleRead Also: Codeigniter 4 Create MVC Example
Activate Errors Reporting:
At this point, we have to turn on the failure of the Codeigniter to deal with errors, which are turned off by default.
Now you go to app/Config/Boot/development.php and set the display_errors to 1 instead of 0. Then do the exact same thing in app/Config/Boot/production.php.
ini_set('display_errors', '1');Install & Configure DomPDF:
At this point, Now we are going to install the DomPDF plugin using the Composer package. Then we will run the below command to install the Composer plugin.
composer require dompdf/dompdfNow we are installing the PDF package in Codeigniter application. Then, go to the app/Config/Autoload.php file and search for $psr4 array, then you have to register the domPDF service.
public $psr4 = [
APP_NAMESPACE => APPPATH, // For custom app namespace
'Config' => APPPATH . 'Config',
'Dompdf' => APPPATH . 'ThirdParty/dompdf/src',
];Read Also: Example Of CodeIgniter 4 Form Validation
Create PDF Controller:
At this point, Now create two functions one for showing the tables in the view. then the second method helps to convert HTML into PDF. Generate a PdfController.php file in the app/Controllers folder. And place the following code inside of it.
<?php
namespace App\Controllers;
use CodeIgniter\Controller;
class PdfController extends Controller
{
public function index()
{
return view('pdf_view');
}
function htmlToPDF(){
$dompdf = new \Dompdf\Dompdf();
$dompdf->loadHtml(view('pdf_view'));
$dompdf->setPaper('A4', 'landscape');
$dompdf->render();
$dompdf->stream();
}
}Define Route:
At this point, you have to create a route that renders the table into the view, Then place the following code in the app/Config/Routes.php file.
$routes->get('/', 'PdfController::index');Create View:
In this last point, you have to create a pdf_view.php file that you will use to convert HTML to PDF. Then place the following code inside the application/views/pdf_view.php file.
<!doctype html>
