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 (2 and 3) and PHP 7.1 or newer.
Install
Via Composer
$ composer require slim/twig-view:3.0.0-beta
Requires Slim Framework 4 and PHP 7.1 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 %}
