We can't really help you if you don't explain what your problem is. What's not working? Can you post some of your code? I assure you it's working and you're probably using it incorrectly.

Hi, i ran into this same issue.
To replicate it, use a fresh install of CI4,
Copy and paste the code example from the user guide
Code:
TypeError
Argument 2 passed to CodeIgniter\Validation\Validation::setRules() must be of the type array, null given, called in /var/www/htdocs/CODEIGNITER/ion.info/system/Controller.php on line 187 search →RE: Form validation not working - qury - 03-28-2017
Hi,
I think i cracked this, so the example was modified as per below and it works:
PHP Code:
<?php
namespace App\Controllers;
use CodeIgniter\Controller;
use Config\Services;
class Form extends Controller {
public $validation;
public function index()
{
helper(['form', 'url']);
$this->validation = \Config\Services::validation();
$this->validation->setRules([
'username' => 'required'
]);
if (!$this->validation->withRequest($this->request)->run())
{
echo view('Signup', [
'validation' => $this->validation
]);
} else
{
echo view('Success');
}
}
}

helper('form');
$validator = new \CodeIgniter\Form\Validator();
I get a class not found error for Validator. I take it this is not the way to do it but the docs do it this way.

Er, the docs don't do it your way... https://bcit-ci.github.io/CodeIgniter4/libraries/validation.html#loading-the-library

Code:$validator = \Config\Services::validation();
The tutorial does it differently. https://bcit-ci.github.io/CodeIgniter4/tutorial/create_news_items.html
