You need
to transfer the flashdata into variable at the first place. And do that in your
controller, then send it to view. Its better to separate logic from
presentation.



 if
            ($this->db->count_all($this->_table) == 0) 

 {

            $this->session->set_flashdata('error', 'Error have.');
 // You doesn't
            need that here...
 // $error = isset($this->session->flashdata('error'))
            ? $this->session->flashdata('error') : FALSE; // Line 36

            redirect('admin/accommodation/insert');
 } 
 else 

            {
 return 0;
 }



// Then
            for validate, in 'admin/accommodation/insert'
$error =
            $this->session->flashdata('error');

$data =
            array();

//...

$data['error'] =
            $error;

$this->load->view('someview',$data);

//
            And in your view file

            id="error_text">

?>
