$add_data['first_name'] = ($this->input->post('first_name') && !empty($this->input->post('first_name'))) ? $this->input->post('first_name') : NULL;     
$add_data['last_name'] = ($this->input->post('last_name') && !empty($this->input->post('last_name'))) ? $this->input->post('last_name') : NULL;     
$data = array(
        'first_name'=>$add_data['first_name'],
        'last_name'=>$add_data['last_name'],
        );  
$this->db->where('id',$add_data['user_id']);

       $saveArr['first_name'] = $this->input->post('first_name');
  }
  if(!empty($this->input->post('last_name')){
       $saveArr['last_name'] = $this->input->post('last_name');
  }
  $this->db->where('id',$add_data['user_id']);
