我在 Codeigniter 的另一個函數(shù)中有問題調(diào)用函數(shù)。所以我有2個功能：功能 1 有控制器用于從數(shù)據(jù)庫中獲取數(shù)據(jù)：public function tampil_halaman_berita()    {        $data['tampil_berita'] = $this->berita->getAllBerita();        $data['tampil_kategori'] = $this->berita->getAllKategori();        $data['tampil_wartawan'] = $this->berita->getAllWartawan();    }函數(shù) 2 從函數(shù) 1 調(diào)用控制器來索引：public function index()    {        $data['judul'] = "Halaman Berita";        $this->tampil_halaman_berita();        $this->load->view('ui/Header');        $this->load->view('pages/Berita', $data);        $this->load->view('ui/Footer');    }但是我收到了這個錯誤，我的函數(shù)tampil_halaman_berita沒有調(diào)用到index()Severity: NoticeMessage: Undefined variable: tampil_beritaFilename: pages/Berita.phpLine Number: 17Backtrace:File: C:\xampp\htdocs\flutter-news\application\views\pages\Berita.phpLine: 17Function: _error_handlerFile: C:\xampp\htdocs\flutter-news\application\controllers\pages\Berita.phpLine: 21Function: viewFile: C:\xampp\htdocs\flutter-news\index.phpLine: 315Function: require_once我不想，像這樣對我的所有函數(shù)重復每個模型，所以我創(chuàng)建了一些函數(shù)，我只是調(diào)用函數(shù)名。public function add(){$data['tampil_berita'] = $this->berita->getAllBerita();        $data['tampil_kategori'] = $this->berita->getAllKategori();        $data['tampil_wartawan'] = $this->berita->getAllWartawan();}public function update(){$data['tampil_berita'] = $this->berita->getAllBerita();        $data['tampil_kategori'] = $this->berita->getAllKategori();        $data['tampil_wartawan'] = $this->berita->getAllWartawan();}我希望你們都明白我的問題。
