Call to a member function …. di codeigniter

coba2 codeigniter,

function GetAll()
{

$this->load->model(‘employee_model’);

$data['query'] =
$this->employee_model->employee_getall();

$this->load->view(‘employee_viewall’, $data);
}

dijalankan ko error

“Call to a member function on a non-object”.

ubah aja jadi

function GetAll()
{
$CI =& get_instance();

$this->load->model(‘employee_model’);

$data['query'] =
$CI->employee_model->employee_getall();

$this->load->view(‘employee_viewall’, $data);
}
