Slim Framework view layer built on top of Twig

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. It works with Twig 1.18+ (PHP5.5+) and with Twig 2 (PHP7).

Install

Via Composer

$ composer require slim/twig-view

Requires Slim Framework 3 and PHP 5.5.0 or newer.

Usage

// Create Slim app
$app = new \Slim\App();

// Fetch DI Container
$container = $app->getContainer();

// Register Twig View helper
$container['view'] = function ($c) {
    $view = new \Slim\Views\Twig('path/to/templates', [
        'cache' => 'path/to/cache'
    ]);
    
    // Instantiate and add Slim specific extension
    $router = $c->get('router');
    $uri = \Slim\Http\Uri::createFromEnvironment(new \Slim\Http\Environment($_SERVER));
    $view->addExtension(new \Slim\Views\TwigExtension($router, $uri));

    return $view;
};

// Define named route
$app->get('/hello/{name}', function ($request, $response, $args) {
    return $this->view->render($response, 'profile.html', [
        'name' => $args['name']
    ]);
})->setName('profile');

// Render from string
$app->get('/hi/{name}', function ($request, $response, $args) {
    $str = $this->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:

• path_for() - returns the URL for a given route.
• base_url() - returns the Uri object's base URL.
• is_current_path() - returns true is the provided route name and parameters are valid for the current path.
• current_path() - renders the current path, with or without the query string.

You can use path_for to generate complete URLs to any Slim application named route and use is_current_path 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="{{ path_for('profile', { 'name': 'josh' }) }}" {% if is_current_path('profile', { 'name': 'josh' }) %}class="active"{% endif %}>Josh</a></li>
    <li><a href="{{ path_for('profile', { 'name': 'andrew' }) }}">Andrew</a></li>
</ul>
{% endblock %}
