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/world
• full_url_for() - returns the URL for a given route. e.g.: http://www.example.com/hello/world
• is_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 the UriInterface object from the incoming ServerRequestInterface object
• base_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 %}
