[quote author="Demostenes Garcia" date="1253167819"]It would be great to use DataMapper Z with the native form_validation from CodeIgniter. I'm having some troubles to repopulate the form.[/quote]

First, DMZ does use the native Form_Validation library for validating. However, you have to do it in a completely different manner. Instead of passing individual fields to the View, pass the entire object. Then print out the object directly. The usual method looks like this:

Code:

$user = new User();
$user->get_by_id($userid);

if($this->input->post('name')) {
    // process form
    $user->name = $this->input->post('name');
    $user->whatever = ...
    ...
    if($user->save()) {
        // redirect
    }
}

$this->load->view('form', array('user' => $user));

Then, in your view, just output $user->name or whatever. Everything the user submitted is automatically processed returned. This also allows you to easily provide error feedback on individual fields.

There are plenty of other examples throughout the extensive documentation, but you can save yourself a ridiculous amount of time by using the included extensions for form handling. You can use them together or separate.

(Also, you aren't using the CI input methods correctly, because they automatically handle escaping the values for you. There is no reason to call htmlspecialchars(). See the form_prep documentation for info.)
