                    $this->emp_model->set($data,$id);
                   // update('info', $data, 'id', $id);
                   //$this->crud->update('info',$data,'id',$id);
                    echo '<script type="text/javascript">alert("Updated Succesfully ");</script>';
                    redirect('employee','refresh');
               }    
        }
        else
        {               
            if(empty($id)){                    
                echo 'add data validation falid ..';
                $this->add();
            }
            else{
                echo 'edit data validation falid ..';
                $this->edit($id);                    
            }          
        }
    }

problem is that when file uploading failed means when file not image or excced file limit it comes into display errors function but i can't load my view ... so please tell me whats problem should there?

Using flashdata and redirect can redirect you while holding your error message for the next request:

if(! $this->upload->do_upload($file_name){
       $error = $this->upload->display_errors();
       $this->session->set_flashdata('error', '$error');
       redirect('/somewhere', 'refresh');
  }
