無法在codeigniter中插入數據

Question

我無法將數據插入數據庫。我不知道問題出在哪裏，但是當我var_dump($this->mberita->get_berita());結果是array(0){}。我是Codeigniter的新手，無法真正弄清楚如何解決這個問題。

模型

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) 
{ 
    $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->db->insert('berita_ukm', $data); 
} 

function validate_berita() 
{ 
    $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) { 
     return TRUE; 
    } 
} 

控制器

function tambah_berita() 
{ 
    if ($this->mberita->validate_berita() == TRUE) { 
     $this->mberita->insert_berita(); 
     redirect('admin/berita/tambah_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); 
} 

請幫我做什麼。謝謝。

<?php 
#in controller page# 
// notes : you should make validation in controller page 

    if ($this->input->post('send')){ //request submit 

    // make form validation 

     $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) { 
      // request data then put in array 
      $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')   
      ); 
     $this->mberita->insert_berita($data); 
     } 
    } 

//模型頁

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