Step 1: Download Codeigniter Project
In this step, you will download the latest version of Codeigniter 4, Go to this link https://codeigniter.com/download Download Codeigniter 4 fresh new setup and unzip the setup in your local system xampp/htdocs/ . And change the download folder name “demo”

Set Base URL like this
public $baseURL = 'http://localhost:8080'; To public $baseURL = 'http://localhost/demo/';
Step 3: Setup Database Credentials
In this step, you need to connect our project to the database. you need to go app/Config/Database.php and open database.php file in text editor. After opening the file in a text editor, you need to set up database credentials in this file like below.
public $default = [ 'DSN' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'demo', 'DBDriver' => 'MySQLi', 'DBPrefix' => '', 'pConnect' => false, 'DBDebug' => (ENVIRONMENT !== 'production'), 'cacheOn' => false, 'cacheDir' => '', 'charset' => 'utf8', 'DBCollat' => 'utf8_general_ci', 'swapPre' => '', 'encrypt' => false, 'compress' => false, 'strictOn' => false, 'failover' => [], 'port' => 3306, ];
Step 4: Install Dompdf Library
In this step, install DomPDF plugin using Composer package. So open your terminal and execute the following command on it:
composer require dompdf/dompdf
After that, Visit app/Config/Autoload.php file and search for $psr4
array, here you have to register the dompdf service.
public $psr4 = [ APP_NAMESPACE => APPPATH, // For custom app namespace 'Config' => APPPATH . 'Config', 'Dompdf' => APPPATH . 'ThirdParty/dompdf/src', ];
Step 5: Create a Controller
In this step, Visit app/Controllers and create a controller name PdfController.php. In this controller, you need to add the following methods into 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(); } }
Step 6: Create a View
In this step, you need to create one view files name pdf-view.php and update the following code into your file:
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <title>Codeigniter 4 PDF Generate Example - Tutsmake.com</title> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"> </head> <body> <div class="container mt-5"> <h2>Codeigniter 4 Generate PDF From View using DOMPdf</h2> <div class="d-flex flex-row-reverse bd-highlight"> <a href="<?php echo base_url('PdfController/htmlToPDF') ?>" class="btn btn-primary"> Download PDF </a> </div> <table class="table table-striped table-hover mt-4"> <thead> <tr> <th>Name</th> <th>Profile</th> <th>City</th> <th>Date</th> <th>CTC</th> </tr> </thead> <tbody> <tr> <td>Airi Satou</td> <td>Accountant</td> <td>Tokyo</td> <td>33</td> <td>2008/11/28</td> <td>$162,700</td> </tr> <tr> <td>Angelica Ramos</td> <td>Chief Executive Officer (CEO)</td> <td>London</td> <td>47</td> <td>2009/10/09</td> <td>$1,200,000</td> </tr> <tr> <td>Ashton Cox</td> <td>Junior Technical Author</td> <td>San Francisco</td> <td>66</td> <td>2009/01/12</td> <td>$86,000</td> </tr> <tr> <td>Bradley Greer</td> <td>Software Engineer</td> <td>London</td> <td>41</td> <td>2012/10/13</td> <td>$132,000</td> </tr> <tr> <td>Brenden Wagner</td> <td>Software Engineer</td> <td>San Francisco</td> <td>28</td> <td>2011/06/07</td> <td>$206,850</td> </tr> <tr> <td>Brielle Williamson</td> <td>Integration Specialist</td> <td>New York</td> <td>61</td> <td>2012/12/02</td> <td>$372,000</td> </tr> <tr> <td>Bruno Nash</td> <td>Software Engineer</td> <td>London</td> <td>38</td> <td>2011/05/03</td> <td>$163,500</td> </tr> <tr> <td>Caesar Vance</td> <td>Pre-Sales Support</td> <td>New York</td> <td>21</td> <td>2011/12/12</td> <td>$106,450</td> </tr> <tr> <td>Cara Stevens</td> <td>Sales Assistant</td> <td>New York</td> <td>46</td> <td>2011/12/06</td> <td>$145,600</td> </tr> <tr> <td>Cedric Kelly</td> <td>Senior Javascript Developer</td> <td>Edinburgh</td> <td>22</td> <td>2012/03/29</td> <td>$433,060</td> </tr> </tbody> </table> </div> </body> </html>
Step 7: Define Routes
In this step, you need to create a route that renders the table into the view, place the following code in app/Config/Routes.php file.
$routes->get('/', 'PdfController::index'); $routes->match([‘get’, ‘post’], ‘PdfController/htmlToPDF’, ‘PdfController::htmlToPDF’);
Step 8: Start Development Server
In this step, open your terminal and execute the following command to start development sever:
php spark serve
