# HttpController

Namespace Chevere\Controller

The HttpController is a special controller meant to be used in the context of HTTP requests. The HttpController extends Controller by adding request parameters (GET, POST, FILES) and Middleware.

All HttpController implement the Interfaces\HttpControllerInterface.

# Accept GET

Define accepted parameters for GET using the acceptGet method.

use function Chevere\Parameter\parameters;
use function Chevere\Parameter\stringParameter;

public function acceptGet(): ParametersInterface
{
    return parameters(
        foo: stringParameter('/^[a-z]+$/'),
    );
}

# Accept POST

Define accepted parameters for POST using the acceptPost method.

use function Chevere\Parameter\parameters;
use function Chevere\Parameter\stringParameter;

public function acceptPost(): ParametersInterface
{
    return parameters(
        bar: stringParameter('/^[1-9]+$/'),
    );
}

# Accept FILES

Define accepted parameters for FILES using the acceptFiles method.


use Chevere\Parameter\Interfaces\ArrayParameterInterface;
use function Chevere\Parameter\arrayParameter;
use function Chevere\Parameter\fileParameter;

public function acceptFiles(): ArrayParameterInterface
{
    return arrayParameter(
        myFile: fileParameter(),
    );
}

# With GET

Set GET parameters using the withGet method. It will only accept arguments complying with Accept GET.

$controller = $controller
    ->withGet($_GET);

# With POST

Set POST parameters using the withPost method. It will only accept arguments complying with Accept POST.

$controller = $controller
    ->withPost($_POST);

# With FILES

Set FILES parameters using the withFiles method. It will only accept arguments complying with Accept FILES.

$controller = $controller
    ->withFiles($_FILES);

# With Middleware

Define middleware using withMiddleware method by passing a collection of PSR Middleware (opens new window) objects.

use Chevere\Controller\HttpMiddleware;

$middleware = new HttpMiddleware(
    new PsrMiddleware(),
    new AnotherPsrMiddleware()
);
$controller = $controller
    ->withMiddleware($middleware);

Middleware priority goes from top to bottom, first in first out (FIFO).

# GET

Use method get to read the GET parameters.

$get = $controller->get();
// within $this context:
$this->get();

# POST

Use method post to read the POST parameters.

$post = $controller->post();
// within $this context:
$this->post();

# FILES

Use method files to read the FILES parameters.

$files = $controller->files();
// within $this context:
$this->files();

# Middleware

Use method middleware to read the HttpMiddleware collection.

$middleware = $controller->middleware();
// within $this context:
$this->middleware();
