Generally we pass id in the Url:

Base_url()/index.php/empAll/25. Now codeigniter automatecaly pass the $id = 25 in the method. In case id not received it will assign the id by 0 and then you will not get this error.

function empAll()
        {     
          $q = $this->db->where('id',$this->input->post('id'))    
                        ->get('employee');        
          if($q->num_rows()>0)
           {    
             foreach($q->result() as $rows)
              {      
                $data[]=$rows;
              }
            }
          return $data;
         }
