CI 1.7 is out now, and the validation lib has been revamped for consistency and clarity. I modified this extension so that I might yet bask in its radiance. So far so good, but since I don’t use Modular Extensions, I can’t verify whether that connection is still intact. I’ve kept the $parent variable alive, though it required a slightly awkward tweak. Modular users, please take a look at my note on the wiki, and let us know how it goes.

Gracias,

Has anyone ever thought of doing something like this?

Create a new MY_Form_validation.php library file in your application/libraries folder:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Form_validation extends CI_Form_validation {
    
    protected $account            = NULL;
    
    // Checks to see if username is avaliable
    protected function username($username)
    {
        $this->CI->load->model('accounts_model');
        
        $account = $this->CI->accounts_model->get_record(array('username' => $username));
        
        if (FALSE !== $account)
        {
            $this->set_message('_check_username', $username . $this->CI->lang->line('form_val_check_username'));
            return FALSE;
        }
        
        return TRUE;
    }
    
    // Checks to see if username exists in DB
    protected function username_exists($username)
    {
        $this->CI->load->model('accounts_model');
        
        $account = $this->CI->accounts_model->get_record(array('username' => $username));
        
        if (FALSE === $account || !is_array($account) || empty($account) || Accounts_Model::STATUS_ACTIVE != $account['status'])
        {
            $this->set_message('_check_username_exists', $username . $this->CI->lang->line('form_val_check_username_exists'));
            return FALSE;
        }
        
        $this->account = $account;
        return TRUE;
    }
    
    // Checks password with account auth_key
    protected function login($password)
    {
        $this->CI->load->library('Authentication');
        
        if (FALSE === $this->CI->authentication->login($this->account['username'], $this->account['auth_key'], $password))
        {
            $this->set_message('_check_master_auth_key', $this->CI->lang->line('form_val_check_master_auth_key'));
            return FALSE;
        }
        
        return TRUE;
    }
    
    // Checks invite code
    protected function invite($invite_id)
    {
        $this->CI->load->model('invites_model');
        
        $invite = $this->CI->invites_model->get_record(array('invite_id' => $invite_id));
        
        if (FALSE !== $invite)
        {
            $this->set_message('_check_invite', $invite_id . $this->CI->lang->line('form_val_check_invite'));
            return FALSE;
        }
        
        return TRUE;
    }
    
    // Checks invite code
    protected function invite_valid($invite_id)
    {
        $this->CI->load->model('invites_model');
        $this->CI->load->model('invite_accounts_model');
        
        $invite = $this->CI->invites_model->get_record(array('invite_id' => $invite_id));
        
        if (FALSE === $invite || !is_array($invite) || empty($invite))
        {
            $this->set_message('_check_invite_valid', $this->CI->lang->line('form_val_check_invite_valid'));
            return FALSE;
        }
        
        if ($this->CI->invite_accounts_model->count(array('invite_id' => $invite_id) >= $invite['allowed'])
        {
            $this->set_message('_check_invite_valid', $this->CI->lang->line('form_val_check_invite_valid'));
            return FALSE;
        }
        
        return TRUE;
    }
}

/* End of file MY_Form_validation.php */
/* Location: ./app/libraries/MY_Form_validation.php */

Then in your controller use the validation functions like so:

$this->form_validation->set_rules('username', $this->lang->line('field_username'), 'trim|required|valid_email|max_length[250]|username_exists');
        $this->form_validation->set_rules('password', $this->lang->line('field_password'), 'required|min_length[5]|login');
        
        if (FALSE === $this->form_validation->run())
        {
            $this->data['message'] = $this->session->flashdata('message');
            $this->data['error'] = $this->session->flashdata('error');
            $this->session->keep_flashdata('redirect');
            $this->load->view('account/login', $this->data);
            return;
        }

OR

$this->form_validation->set_rules('invite', $this->lang->line('field_invite'), 'trim|required|alpha_numeric|max_length[50]|strtolower|invite_valid');
        $this->form_validation->set_rules('username', $this->lang->line('field_username'), 'trim|required|valid_email|max_length[250]|username');
        $this->form_validation->set_rules('password', $this->lang->line('field_password'), 'required|min_length[5]|matches[passconf]');
        $this->form_validation->set_rules('passconf', $this->lang->line('field_passconf'), 'required');
        $this->form_validation->set_rules('firstname', $this->lang->line('field_firstname'), 'trim|max_length[50]');
        $this->form_validation->set_rules('lastname', $this->lang->line('field_lastname'), 'trim|max_length[50]');
        
        if (FALSE === $this->form_validation->run())
        {
            $this->load->view('account/create');
            return;
        }
