My routes for new endpoint:

$app->get('/user/notification', 'UserController:getNotification');

My class:

class UserController{
    public function __construct($container)
    {
        // make the container available in the class
        $this->container = $container;
    }

    public function getNotification($request, $response, $args){
        //my code here
    }
}

my dependencies.php:

use AppControllersUserController;
$container = $app->getContainer();
$container['UserController'] = function ($c) {
    return new UserController($c);
};

my composer.json

{
    "name": "slim/slim-skeleton",
    "autoload": {
        "psr-4": {
           "App": "src/"
        }
    }
}

tried to composer dump-autoload but that did not work.

Answer 1

PHP cannot find your class.

1. require it in the index.php
2. Fix your PSR-0/4 autoload schema and then dump-autoload
