You need to pass your query result to your view
Controller
public function edit_desig(){
$this->load->model('designation_model');
$designation=$this->designation_model->edit_designation($id);// assing your query result to your variable
$data['designation'] = designation;// pas your variavle to data arrray
$this->load->view('view_name', $data);// load your view with array
}
As per your view code you need to fetch data in array form in your model
Models
public function edit_designation($id){
$query=$this->db->get_where('designation',array('desig_id'=>$id));
return $query->result_array();// change this to array
}
