无法将身份更改为“用户名”；在 Codeigniter Ion Auth 中？

Question

我已经安装了 ion auth，一切都正常运行。我遇到的唯一问题是我想更改登录名以使用访客用户名而不是电子邮件。我更改了 ion_auth.php 配置文件中的 CONFIG 选项，但它仍然不起作用。我缺少额外的步骤吗？

ion_auth

/**
 * A database column which is used to
 * login with.
 **/
$config['identity']            = 'username';

在控制器

//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()模型中配置login()

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

为什么您仍在控制器中处理电子邮件（而不是用户名）？

Answer 2

您需要更改控制器，因为它仍在从 POST 获取电子邮件并使用它来尝试登录。

Answer 3

您应该在用户表的用户名列中添加索引
