newb question, validation not successful even when it should be

[eluser]Unknown[/eluser]
This code doesn't seem to work. When I submit my form, and validation is successful, it just still goes back to the form. It appears $this->form_validation->run() is returning false even though no errors are showing in the validation. Also, I removed the is_unique attribute to see if that was causing problems and it behaved the same.

What am I doing wrong?

Code:

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

class MyAccount extends CI_Controller {

/**
  * Index controller for myaccount
         * Created from welcome.php
  */
public function signup()
{
  $data['title'] = 'Register';

  $this->load->database();

  $this->load->helper(array('form', 'url'));

  $this->load->library('form_validation');


  if ($this->form_validation->run() == FALSE)
  {

   //create the form
   $this->load->helper('form');

   $data['form_signup'] = form_open('myaccount/signup');
   $data['form_signup'] .= form_label('Please enter a username for sign-in purposes:'.form_input('username', set_value('username')), '');
   $data['form_signup'] .= form_error('username');

   $data['form_signup'] .= form_label('Password:'.form_password('password', set_value('password')), '');
   $data['form_signup'] .= form_error('password');

   $data['form_signup'] .= form_label('Confirm password:'.form_password('passconf', set_value('passconf')), '');
   $data['form_signup'] .= form_error('passconf');

   $data['form_signup'] .= form_submit('signup', 'Sign Up!');
   $data['form_signup'] .= form_close();
  

   $this->load->view('myaccount/signup',$data);

  } else {
   //insert the data into the db

   //if successful, show success page
   $this->load->view('myaccount/signup_success',$data);
  }


}
}

/* End of file myaccount.php */
/* Location: ./application/controllers/myaccount.php */

Code:

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

/**
  * Form validation configuration
         * Created from help docs
*/


$config = array(
                                    array(
                                            'field' => 'username',
                                            'label' => 'Username',
                                            'rules' => 'required|min_length[4]|max_length[30]|alpha_dash|is_unique[users.username]'
                                         ),
                                    array(
                                            'field' => 'password',
                                            'label' => 'Password',

                                            'label' => 'PasswordConfirmation',
                                            'rules' => 'required|matches[password]'
                                         )
               );
/* End of file form_validation.php */

Are you sure no errors are being returned? I don't see you echoing the validation_errors() function anywhere, which is what would tell you what errors the validation library is generating.

Thanks for that tip. That didn't cause the problem, but once I stuck that in there the form started working properly (this is now what, 2 weeks later ). Maybe it was some sort of session/cookie bug.
