Anonymous controller and trait class for Slim3

Slim3-controller

, _(*1)

Anonymous controller and trait for Slim3 with PHP7. We can use anonymous classes in PHP7. So I use anonymous classes instead of anonymous functions. Slim3 now supports PSR-7 interfaces for its Request and Response objects. And Slim3 uses extends objects, and use it in your anonymous functions., _(*2)

But we use Request and Response object directly, so I try to use anonymous classes to write controller action logic and it is to be readability. read more, _(*3)

Requirements

• PHP 7.0 or later.
• Slim3

Install

install via composer, _(*4)

composer require brtriver/slim3-controller

Usage

you can read example code., _(*5)

sample code is blow:, _(*6)

use Brtriver\Controller\Controller;

$app->get('/hello/{name}', new class($app) extends Controller {

        public function action($args)
        {
            return $this->render($this->container['greet'] . $args['name']);
        }
});

• Controller class has these methods and class properties.
  • methods:
  • action($args): you should write your controller logic in this method.
  • render($output): helper method to render the $output with 200 status
  • render404($output): helper method to render the $output with 404 status
  • properties:
  • $this->request
  • $this->response
  • $this->app
  • $this->container

If use Template engine (PHP or Twig etc...), a renderWithT method in Templatable trait is available:, _(*7)

use Brtriver\Controller\Controller;
use Brtriver\Controller\Templatable;
$app->get('/hello/{name}', new class($app) extends Controller {
        use Templatable;

        public function action($args)
        {
            return $this->renderWithT('web.html', ['name' => $args['name']]);
        }
});
