Codeigniter会话在本地工作正常,但不适用于Godaddy

Question

我在php框架(Codeigniter)上开发了网站,在我的本地(WAMP服务器)上工作正常.当我将它上传到Godaddy托管时,它无法登录网站.以下是登录类功能.

public function index()
{

    if ($this->session->userdata('admin_login') == 1)
        redirect(base_url() . 'index.php?admin/dashboard', 'refresh');


     $this->load->view('backend/login');
}


function ajax()
{
    $response = array();


    $email      = $_POST["email"];
    $password   = $_POST["password"];
    $response['submitted_data'] = $_POST;       


    $login_status = $this->validate_login( $email ,  sha1($password) );
    $response['login_status'] = $login_status;
    if ($login_status == 'success') {
        $response['redirect_url'] = '';
    }

    echo json_encode($response);
}


function validate_login($email  =   '' , $password   =  '')
{
    $credential =   array(  'email' => $email , 'password' => $password );

    $query = $this->db->get_where('users' , $credential);

    if ($query->num_rows() > 0) {
        $row = $query->row();
          $this->session->set_userdata('admin_login', '1');
          $this->session->set_userdata('admin_id', $row->id);
          $this->session->set_userdata('name', $row->name);
          $this->session->set_userdata('login_type', 'admin');

          return 'success';
    }

    return 'invalid';
}

我意识到$ this-> session-> set_userdata()方法不适用于godaddy.

Please try this 
Please add  session library  just like below.

$this->load->library('session');
if ($this->session->userdata('admin_login') == 1)
        redirect(base_url() . 'index.php?admin/dashboard', 'refresh');



     $this->load->view('backend/login');
