Introduction

This package allows the use of "controllers" with the Slim framework.

Synopsis

Define the controllers

$ tree /path
/path
└── to
    └── controllers
        ├── ProfileController.php
        └── UserController.php

Please note the suffix used to create the controllers' file names: "Controller.php". This suffix can be changed.

<?php

namespace dbeurive\Slim\Test\controller0;
use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Message\ResponseInterface as Response;
use dbeurive\Slim\controller\Controller;

/**
 * Class ProfileController
 * @package dbeurive\Slim\Test\controller0
 */
class ProfileController extends Controller
{
    /**
     * Create or update a profile.
     * @param Request $request
     * @param Response $response
     * @return Response
     */
    public function actionPostSet(Request $request, Response $response) {
        $response->getBody()->write("Profile has been set! (" . $this->app->getContainer()[FLAG] . ')');
        return $response;
    }

    /**
     * Get a profile.
     * @param Request $request
     * @param Response $response
     * @return Response
     * @uri-params {id}
     */
    public function actionGetGet(Request $request, Response $response) {
        $response->getBody()->write("This is the requested profile data (" . $this->app->getContainer()[FLAG] . ')');
        return $response;
    }
}

Please note the names of the methods that implement the controllers' actions ("actionPostSet" and "actionGetGet"). Actions' names start with the prefix "action", followed by the name of the expected HTTP method (see the Slim's documentation).

Please note the annotation "@uri-params {id}" (for the method "actionGetGet()"). This means that the URI associated with this action is "/profile/get/{id}".

Please have a look to the controller ProfileController.php and the controller UserController.php.

Create the index that lists all controllers

php slim-controller.php index --index-path /app/data/index.json /path/to/controllers/

The index "/app/data/index.json" contains data about the controllers. Please click here to see the content of this file.

Please click here to see the script slim-controller.php.

You can dump the content of the index in a human readable way:

$ php slim-controller.php dump --host http://www.slim-controller.localhost /app/data/index.json
POST   http://www.slim-controller.localhost/profile/set
       /path/to/controllers/ProfileController.php
       \dbeurive\Slim\Test\controller0\ProfileController::actionPostSet
GET    http://www.slim-controller.localhost/profile/get/{id}
       /path/to/controllers/ProfileController.php
       \dbeurive\Slim\Test\controller0\ProfileController::actionGetGet
POST   http://www.slim-controller.localhost/user/login
       /path/to/controllers/UserController.php
       \dbeurive\Slim\Test\controller0\UserController::actionPostLogin
GET    http://www.slim-controller.localhost/user/get/{id}
       /path/to/controllers/UserController.php
       \dbeurive\Slim\Test\controller0\UserController::actionGetGet

Implement the Slim application

use dbeurive\Slim\controller\Manager as ControllerManager;

$app = new \Slim\App([]);
ControllerManager::start($app, '/app/data/index.json');
$app->run();

Please note that, within this example, only the actions within the expected controller (depending on the URL) will be declared. For example, let's says that the URL is: http://www.slim-controller.localhost/profile/get/10. The expected controller is "ProfileController".

This behaviour can be modified. Indeed, it is possible to configure the controller manager so that it will systematically register all routes (from all controllers). To do that, we should have written: ControllerManager::start($app, '/app/data/index.json', true);
