Plates Template Engine - URI extension same as Twig 'pathFor'?

Question

I'm working thru a tutorial on the Slim framework. The author uses Twig, and I'd prefer to use the Plates template engine. I've been able to modify all lessons to use the Plates template, until the author started using baseUrl and pathFor extensions.

I see that Plates has an extension called URI, which I think is synonymous with Twig's pathFor.

Unfortunately, I can't for the life of me figure out how to get it enabled. Reading the documentation, I thought the following code would do it, but so far no luck.

require 'vendor/autoload.php';

$app = new Slim\App([
    'settings' => [
        'displayErrorDetails' => true
    ]
]);

$container = $app->getContainer();

$container['view'] = function ($container) {
    $plates = new League\Plates\Engine(__DIR__ . '/templates');
    $plates->loadExtension(new League\Plates\Extension\URI($_SERVER['PATH_INFO']));
    return $plates;
};

$app->get('/contact', function($request, $response) {
    return $this->view->render('contact');
});

$app->post('/contact', function($request, $response) {
    return $response->withRedirect('http://slim-local.com/contact/confirm');
})->setName('contact');

$app->get('/contact/confirm', function($request, $response) {
    return $this->view->render('contact_confirm');
});

$app->run();

And then in the template, the author used the pathFor extension to populate a form's action parameter. I am trying to use Plates' URI extention to do the same like so:

<form action="<?=$this->uri('contact')?>" method="post">

Has anybody used this template engine and the URI extension with Slim specifically? Am I mistaken that it is basically synonymous with Twig's pathFor extension? Should I give up and just use Twig? thanks for your advice.

You can use the URI from the environment.

Slim 3 example:

$container['view'] = function ($container) {
    $plates = new \League\Plates\Engine(__DIR__ . '/templates');

    $uri = \Slim\Http\Uri::createFromEnvironment(new \Slim\Http\Environment($_SERVER));
    $plates->loadExtension(new \League\Plates\Extension\URI($uri->__toString()));

    return $plates;
};
