Slim3 controller management

NOTICE: To anyone using this package you should consider moving to juliangut/slim-routing

Class route creation boilerplate, allows you to define your controller classes as services to be pulled out from container easily, extending from a base controller class.

I strongly suggest you don't use this library but for rapid prototyping or certain use cases. If you really want to follow SOLID principles, don't use this package and either directly inject your dependencies in the controller class, use the container to create and inject dependencies or try another container such as PHP-DI with juliangut/slim-php-di

I cannot stress this enough, this library is meant to be used with default Slim container and for certain cases only.


Best way to install is using Composer:

composer require juliangut/slim-controller

Then require_once the autoload file:

require_once './vendor/autoload.php';


use \Jgut\Slim\Controller\Resolver;

// Define your controllers
$controllers = [

// Create Slim app and fetch DI Container
$app = new \Slim\App();
$container = $app->getContainer();

// Register Controllers
foreach (Resolver::resolve($controllers) as $controller => $callback) {
    $container[$controller] = $callback;

// Define route (\MyController has already been registered)
$app->get('hello/app', '\MyController:dispatch');

// Run app

If your controller implements Jgut\Slim\Controller\Controller it has the DI container automatically injected, you can access it by getContainer method.

If your controller extends Jgut\Slim\Controller\Base you can also directly access container services the same way you do on a Closure route callback. Simply take care to not define class attributes with the same name as services in the container. To do this container is injected in the controller and __get and __isset magic methods are defined to look into the container.

use Jgut\Slim\Controller\Base as BaseController;

class MyController extends BaseController
    public function displatch($request, $response, array $args)
        // Pull Twig view service given it was defined
        return $this->view->render($response, 'dispatch.twig');

You can use the resolver to define your class routes callback and not implement Controller or extend Base on those classes, in this case your controller won't have access to the container but it will still be a valid callback.

Important notice

As a general rule of thumb directly injecting container is considered a bad practice as you are actually hiding your dependencies, by fetching them from the container, instead of defining them in the class. You'll be using the container as a service locator rather than a true DIC.


This controller registration works only for controllers whose constructor doesn't need any parameters. In case you need a controller with paramenters in its __construct() method you can still benefit from \Jgut\Slim\Controller\Controller but you have to register it yourself.

use Jgut\Slim\Controller\Controller;

$container['\MyController'] = function($container) {
    $controller = new \MyController('customParameter');

    // Set container into the controller
    if ($controller instanceof Controller) {

    return $controller;
