[SOLVED] - Strange problem with POST data

You can process POST with:

$request = \Config\Services::request();

$name = $request->getPost('name');
$lastname = $request->getPost('lastname');

I tryed but don't work:
Test.php:

Code:

<?php namespace App\Controllers;

use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\Response;

class Test extends BaseController
{

public function index()
{
            $response = service('response');       
            //$request = service('request');
            $request = \Config\Services::request();
           
            echo $request->uri->getPath()."<br>";
            echo $request->getMethod()."<br>";
           
            $name = $request->getPost('name');
            $lastname = $request->getPost('lastname');
            echo 'StarttestingName'.$name.'EndtestingName<br>';
           
            if ($request->getVar('submit'))
                {
                    if (isset($_POST['name']))
                        {
                            echo "Nome: ".$_POST['name']."<br>";
                        }   
                    if (isset($_POST['lastname']))
                        {
                            echo "Cognome: ".$_POST['lastname'];
                        }
                    return view('test_1');
                } else
                    {
                        return view('test_2');
                    }
}

//--------------------------------------------------------------------

}

Output:

Code:

test<br>get<br>StarttestingNameEndtestingName<br><!-- DEBUG-VIEW START 1 APPPATH/Config/../Views/test_2.php -->

Test 2 nessun post

<form action="test" method="post">

<input type="text" name="name" value="Mario" id="name">

<input type="text" name="lastname" value="Rossi" id="lastname">

<input type="submit" name="submit" value="submit" id="submit">

</form>

<!-- DEBUG-VIEW ENDED 1 APPPATH/Config/../Views/test_2.php -->



<script type="text/javascript" id="debugbar_loader" data-time="1600853547" src="[url=http://www.yiisupertest.com/?debugbar]http://www.yiisupertest.com/?debugbar[/url]"></script><script type="text/javascript" id="debugbar_dynamic_script"></script><style type="text/css" id="debugbar_dynamic_style"></style>

as you can see in the output, the variable "name" is empty, and there is nothing between the two strings testingname.....
I'm going crazy.....
