Kohana 3: Example of model with validation

Question

I find examples and tutorials about models and about validation. And I places that say the validation (or most of it at least) should be in the model, which I agree with. But I

Answer 1

Here's a simple example that works for me.

In my model (client.php):

  ''
);

public function __construct() {
    // load database library into $this->db (can be omitted if not required)
    parent::__construct();

    $this->validation = new Validation($_POST);
    $this->validation->pre_filter('trim','clientName');
    $this->validation->add_rules('clientName','required');
}

public function create() {
    return $this->validation->validate();
}

// This might go in base Model class
public function getFormValues() {
    return arr::overwrite($this->fields, $this->validation->as_array());
}

// This might go in base Model class
public function getValidationErrors() {
    return arr::overwrite($this->fields, $this->validation->errors('form_errors'));
}
}

?>

In my controller (clients.php):

foobar = 'bob.';

    $this->template->content = $content;
    $this->template->render(TRUE);

}

/* A new user signs up for an account. */
public function signup() {

    $content = new View('clients/create');
    $post = $this->input->post();
    $client = new Client_Model;

    if (!empty($post) && $this->isPostRequest()) {
        $content->message = 'You submitted the form, '.$this->input->post('clientName');
        $content->message .= '
Performing Validation
';

        if ($client->create()) {
            // Validation passed
            $content->message .= 'Validation passed';
        } else {
            // Validation failed
            $content->message .= 'Validation failed';
        }

    } else {
        $content->message = 'You did not submit the form.';
    }

    $contnet->message .= '
';
    print_r ($client->getFormValues());
    print_r ($client->getValidationErrors());


    $this->template->content = $content;
    $this->template->render(TRUE);
}

   }
?>

In my i18n file (form_errors.php):

$lang = Array (
'clientName' => Array (
'required' => 'The Client Name field is required.'
)
);
