Slim Framework Twig View
This is a Slim Framework view helper built on top of the Twig templating component. You can use this component to create and render templates in your Slim Framework application.
Install
Via Composer
$ composer require slim/twig-view
Requires Slim Framework 4, Twig 3 and PHP 7.4 or newer.
Usage
use DI\Container;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
require __DIR__ . '/vendor/autoload.php';
// Create Container
$container = new Container();
AppFactory::setContainer($container);
// Set view in Container
$container->set('view', function() {
return Twig::create('path/to/templates', ['cache' => 'path/to/cache']);
});
// Create App
$app = AppFactory::create();
// Add Twig-View Middleware
$app->add(TwigMiddleware::createFromContainer($app));
// Define named route
$app->get('/hello/{name}', function ($request, $response, $args) {
return $this->get('view')->render($response, 'profile.html', [
'name' => $args['name']
]);
})->setName('profile');
// Render from string
$app->get('/hi/{name}', function ($request, $response, $args) {
$str = $this->get('view')->fetchFromString(
'<p>Hi, my name is {{ name }}.</p>',
[
'name' => $args['name']
]
);
$response->getBody()->write($str);
return $response;
});
// Run app
$app->run();
Without container
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
require __DIR__ . '/vendor/autoload.php';
// Create App
$app = AppFactory::create();
// Create Twig
$twig = Twig::create('path/to/templates', ['cache' => 'path/to/cache']);
// Add Twig-View Middleware
$app->add(TwigMiddleware::create($app, $twig));
// Define named route
$app->get('/hello/{name}', function ($request, $response, $args) {
$view = Twig::fromRequest($request);
return $view->render($response, 'profile.html', [
'name' => $args['name']
]);
})->setName('profile');
// Render from string
$app->get('/hi/{name}', function ($request, $response, $args) {
$view = Twig::fromRequest($request);
$str = $view->fetchFromString(
'<p>Hi, my name is {{ name }}.</p>',
[
'name' => $args['name']
]
);
$response->getBody()->write($str);
return $response;
});
// Run app
$app->run();
Custom template functions
TwigExtension provides these functions to your Twig templates:
url_for()- returns the URL for a given route. e.g.: /hello/worldfull_url_for()- returns the URL for a given route. e.g.: http://www.example.com/hello/worldis_current_url()- returns true is the provided route name and parameters are valid for the current path.current_url()- returns the current path, with or without the query string.get_uri()- returns theUriInterfaceobject from the incomingServerRequestInterfaceobjectbase_path()- returns the base path.
You can use url_for to generate complete URLs to any Slim application named route and use is_current_url to determine if you need to mark a link as active as shown in this example Twig template:
{% extends "layout.html" %}
{% block body %}
<h1>User List</h1>
<ul>
<li><a href="{{ url_for('profile', { 'name': 'josh' }) }}" {% if is_current_url('profile', { 'name': 'josh' }) %}class="active"{% endif %}>Josh</a></li>
<li><a href="{{ url_for('profile', { 'name': 'andrew' }) }}">Andrew</a></li>
</ul>
{% endblock %}
