PHP Luminova: Base Class for HTTP Routing Controllers

The BaseController is a core element of Luminova's MVC architecture, functioning as an intermediary between the router and template engines. It suitable for handling backend operations by receiving instructions from the router and conveying them to the template for processing. While similar to the BaseViewController, but differs in its approach to request handling and validation. It initializes the class on the go, making easy access to validation user inputs and interact with request objects without requiring class initialization beforehand.

While primarily designed for backend operations, the BaseController remains compatible with frontend applications, offering a seamless integration between frontend and backend components.

• Class namespace: \Luminova\Base\BaseController
• This class is an Abstract class

Example usages

In other to use BaseController class, you will need to extend it whenever you want create a new controller class.

Below is an example of how a basic controller class should look like.

<?php 
namespace App\Controllers;
use \luminova\Base\BaseController;

class BackendController extends BaseController 
{
    public function __construct()
    {
        parent::__construct();
    }

    public function addUser(): int 
    {
        $name = escape($this->request->getPost('name'));
        $added = $builder->table('users')->insert([
            [
                'name' => $name,
                //...
            ]
        ]);
        return $added ? STATUS_SUCCESS : STATUS_ERROR;
    }
}

Properties

Access to HTTP request object.

protected ?\Luminova\Http\Request $request = null;

Access to input validation object.

protected ?\Luminova\Security\Validation $validate = null;

Access to application object.

protected ?\App\Application $app = null;

view

The view method serves as a convenient alias or shorthand for rendering views within the controller class. It is equivalent to $this->app->view('view', 'type')->render().

Return Value:

int - Return STATUS_SUCCESS on success, otherwise STATUS_ERROR failure.

protected onCreate(): void

onDestroy

The onDestroy method in the controller acts as an alternative to __destruct. It is called after the __destruct method has completed its execution.

protected onDestroy(): void
