Как передать данные отправки из метода контроллера в метод модели в CodeIgniter [закрыто] ⇐ Php

[Anonymous]

Мне не удалось вставить данные в базу данных, ошибка не отображается. Я пробую var_dump($this->mberita->get_berita()); но массив(0){}.
модель:
function get_berita()
{
$this->db->order_by('id_berita','asc');
$data = $this->db->get('berita_ukm');
return $data->result();
}

//untuk menambah berita
function insert_berita($data)
{
$this->db->insert('berita_ukm', $data);
}

контроллер
function index()
{
$this->data['berita'] = $this->mberita->get_berita();
$this->data['title'] ='UKM Taekwondo | berita';
$this->data['orang'] = $this->mlogin->dataPengguna($this->session->userdata('username'));
$this->data['contents'] = $this->load->view('admin/berita/view_berita', $this->data, true);
$this->load->view('template/wrapper/admin/wrapper_ukm',$this->data);
}

function tambah_berita()
{
if ($this->input->post('submit')) {
$this->form_validation->set_rules('id_berita', 'Id Berita', 'required|numeric');
$this->form_validation->set_rules('tanggal', 'Tanggal', 'required');
$this->form_validation->set_rules('judul_berita', 'Judul Berita', 'required');
$this->form_validation->set_rules('content', 'Content', 'required');

if ($this->form_validation->run() == TRUE)
{
$data = array(
'id_berita' => $this->input->post('id_berita'),
'tanggal' => $this->input->post('tanggal'),
'judul_berita' => $this->input->post('judul_berita'),
'content' => $this->input->post('content')

);
$this->mberita->insert_berita();
}
}

$this->data['orang'] = $this->mlogin->dataPengguna($this->session->userdata('username'));
$this->data['contents'] = $this->load->view('admin/berita/tambah_berita', '', true);
$this->load->view('template/wrapper/admin/wrapper_ukm',$this->data);
}
