PHP Codeigniter (Controller - View)

Saya mau bertanya saya cara mengembalikan nilai (nama subjek)supaya dapat ditampilkan di menu user menggunakan PHP Codeigniter itu bagaimana? Untuk kode controller nya sbb : public function view_soal($id_mapel,$id_paket){ // needed data $data['data_subjek'] = $this->master->get_all_data('tb_subjek')->result(); $id_subjek = $this->input->post('subjek'); $where = array('id_mapel'=>$id_mapel,'id_subjek'=>$id_subjek); $data['data_mapel'] = $this->master->find_data(array('id_mapel'=>$id_mapel),'tb_mapel')->row_array(); $data['data_subjek_data'] = $this->master->find_data(array('id'=>$id_subjek),'tb_subjek')->row_array(); //get data paket $where_paket = array('id'=>$id_paket); $data['data_paket'] = $this->master->find_data($where_paket,'tb_paket')->row_array(); //get data view $data['data_view'] = $this->db->query("select a.*,b.nama_tema from tb_pertanyaan a inner join tb_tema b on a.id_tema = b.id_tema where a.id_tema IN(select id_tema from detil_paket where id_paket ='$id_paket')")->result(); $data['add_link'] = 'training'; $data['view_file'] = $this->training.'view_soal'; $this->load->view('template/media',$data); }

untuk kode view nya sbb :

'.strtoupper($data_mapel['nama_mapel']).'  ('.$data_subjek_data['nama_subjek'].')'; ?>
