我有自动加载的会话库
控制器登录
class Login extends CI_Controller {
function __construct() { parent::__construct(); }
function index() { $this->load->helper(array('form')); $this->load->view('login_view'); }
}
?> ;
控制器验证登录
class VerifyLogin extends CI_Controller {
function __construct() { parent::__construct(); $this->load->model('user','',TRUE); }
function index() { //This method will have the credentials validation $this->load->library('form_validation');

模型用户
db -> select('id, username, password'); $this -> db -> from('users'); $this -> db -> where('username', $username); $this -> db -> where('password', MD5($password)); $this -> db -> limit(1);
$query = $this -> db -> get();
if($query -> num_rows() == 1) { return $query->result(); } else { return false; } } } ?> ;
