Send value to menu view

Hi , sorry for english , in every controller i have :

Code:

       $this->load->view('templates/header_user',$data);
       $this->load->view('templates/menu_user',$data);
       $this->load->view('controller/view', $data);
       $this->load->view('templates/footer_user',$data);

Because menu_user are used in several controller  and i want send a value  to menu , how can i do this ?
