I used Twig with Symfony and I really loved it. I now have a CodeIgniter project and I want to integrate Twig with it.
I installed the latest versions of CodeIgniter and Twig via Composer and and followed this tutorial but I believe the code in the tutorial is for CI v3.
Could anyone who has integrated Twig with CI v4 help me with the proper code please.
solution below!

Try this I hope it will help you
Install Composer and run the following command to get the latest version:
composer require "twig/twig:*"
Then after installation add this line of code to the Services.php file in the config folder, that is, app => Config => Services.php, just like the code below
....
public static function twig($viewDir = null, $getShared = true)
{
if ($getShared) {
return static::getSharedInstance('twig', $viewDir);
}
$appPaths = new \Config\Paths();
$appViewPaths = $viewDir ?? $appPaths->viewDirectory;
$loader = new \Twig\Loader\FilesystemLoader($appViewPaths);
return new \Twig\Environment($loader, [
'cache' => WRITEPATH.'/cache/twig',
]);
}
....
**Then in your controller call the services method you just created, just like this
namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;
use Config\Services; // Add the services namespace
class BaseController extends Controller
{
protected $helpers = [];
protected $twig;
// protected $helper = [];
public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
{
parent::initController($request, $response, $logger);
$this->twig = Services::twig(); // call the twig service you just created
}
}
So with this now you can call the view files in other controllers extends to parent controller BaseController e.g
namespace App\Controllers;
class Home extends BaseController
{
public function index ()
{
// To load a template from a Twig environment, call the load() method which returns a \Twig\TemplateWrapper instance:
$template = $this->twig->load('index.html');
// To render the template with some variables, call the render() method:
return $template->render(['the' => 'variables', 'go' => 'here']);
// The display() method is a shortcut to output the rendered template.
// OR You can also load and render the template in one fell swoop:
return $this->twig->render('index.html', ['the' => 'variables', 'go' => 'here']);
// If a template defines blocks, they can be rendered individually via the renderBlock() call:
return $template->renderBlock('block_name', ['the' => 'variables', 'go' => 'here']);
// Note any of them above will work
}
}
If you still want to use view() with twig like codeigniter 4 default view function you can modify the Common.php file in app directory
by adding this block of code below.
if (!function_exists('view'))
{
function view($tpl, $data = []) {
$twig = \Config\Services::twig(); // call the twig service you just created
return $twig->render($tpl, $data);
}
}
Then in controller call it like this
return view('index', ['name' => 'Chibueze Agwu'])
Then in view file index.twig
<!DOCTYPE html>
<html>
<head>
<title>My Webpage</title>
</head>
<body>
<h1>My Webpage</h1>
{{ name }}
</body>
</html>
This will output
My Webpage
Chibueze Agwu
I haven't test this code but I hope it will work. If not call my attentions.
In order to obey the the rule of DRY (DO NOT REPEAT YOURSELF), you can go ahead to improve the code I will do that later
