Unable to change Identity to 'username' in Codeigniter Ion Auth? - php

Question

I have installed ion auth and everything is up and functional. The only problem I have is I want to change the login to use the visitors username instead of e-mail. I change the CONFIG option in the ion_auth.php config file and it still doesnt work. Is there an extra step Im missing??
ion_auth config
/**
* A database column which is used to
* login with.
**/
$config['identity'] = 'username';
login() in the controller
//log the user in
function login()
{
$this->data['title'] = "Login";
//validate form input
$this->form_validation->set_rules('email', 'E-mail Address', 'required|valid_email');
$this->form_validation->set_rules('password', 'Password', 'required');
if ($this->form_validation->run() == true)
{ //check to see if the user is logging in
//check for "remember me"
$remember = (bool) $this->input->post('remember');
if ($this->ion_auth->login($this->input->post('email'), $this->input->post('password'), $remember))
{ //if the login is successful
//redirect them back to the home page
$this->session->set_flashdata('message', $this->ion_auth->messages());
redirect($this->config->item('base_url'), 'refresh');
}
else
{ //if the login was un-successful
//redirect them back to the login page
$this->session->set_flashdata('message', $this->ion_auth->errors());
redirect('auth/login', 'refresh'); //use redirects instead of loading views for compatibility with MY_Controller libraries
}
}
else
{ //the user is not logging in so display the login page
//set the flash data error message if there is one
$this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
$this->data['email'] = array('name' => 'email',
'id' => 'email',
'type' => 'text',
'value' => $this->form_validation->set_value('email'),
);
$this->data['password'] = array('name' => 'password',
'id' => 'password',
'type' => 'password',
);
$this->load->view('auth/login', $this->data);
}
}
login() model
public function login($identity, $password, $remember=FALSE)
{
if (empty($identity) || empty($password) || !$this->identity_check($identity))
{
return FALSE;
}
$query = $this->db->select($this->identity_column.', id, password, group_id')
->where($this->identity_column, $identity)
->where('active', 1)
->where($this->ion_auth->_extra_where)
->limit(1)
->get($this->tables['users']);
$result = $query->row();
if ($query->num_rows() == 1)
{
$password = $this->hash_password_db($identity, $password);
if ($result->password === $password)
{
$this->update_last_login($result->id);
$group_row = $this->db->select('name')->where('id', $result->group_id)->get($this->tables['groups'])->row();
$session_data = array(
$this->identity_column => $result->{$this->identity_column},
'id' => $result->id, //kept for backwards compatibility
'user_id' => $result->id, //everyone likes to overwrite id so we'll use user_id
'group_id' => $result->group_id,
'group' => $group_row->name
);
$this->session->set_userdata($session_data);
if ($remember && $this->config->item('remember_users', 'ion_auth'))
{
$this->remember_user($result->id);
}
return TRUE;
}
}
return FALSE;
}

Answer 1

Why are you still processing email in the controller (instead of username)?

Answer 2

You need to change your controller since it is still grabbing email from POST and using it to try to login.

Answer 3

You should add an index in the users table of username column
