Codeigniter：控制器内的Call函数

我在Codeigniter的另一个函数中有问题调用函数。所以我有2个功能：

功能1具有 Controller 用于从数据库中获取数据：

public function tampil_halaman_berita()
    {
        $data['tampil_berita'] = $this->berita->getAllBerita();
        $data['tampil_kategori'] = $this->berita->getAllKategori();
        $data['tampil_wartawan'] = $this->berita->getAllWartawan();
    }

功能2调用控制器从功能1到索引：

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');
    }

但是我收到此错误，我的函数 tampil_halaman_berita 没有调到 index（） 

Severity: Notice

Message: Undefined variable: tampil_berita

Filename: pages/Berita.php

Line Number: 17

Backtrace:

File: C:\xampp\htdocs\flutter-news\application\views\pages\Berita.php
Line: 17
Function: _error_handler

File: C:\xampp\htdocs\flutter-news\application\controllers\pages\Berita.php
Line: 21
Function: view

File: C:\xampp\htdocs\flutter-news\index.php
Line: 315
Function: require_once

我不想像这样对我的所有函数重复每个Model，所以我创建了一个函数，我只是调用了函数名。

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();
}

希望大家都理解我的问题。

谢谢

  

如果您需要我的完整控制器

<?php
class Berita extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->library('session');
        $this->load->model('pages/Berita_model', 'berita');
    }
    public function tampil_halaman_berita()
    {
        $data['tampil_berita'] = $this->berita->getAllBerita();
        $data['tampil_kategori'] = $this->berita->getAllKategori();
        $data['tampil_wartawan'] = $this->berita->getAllWartawan();
    }
    public function index()
    {
        $data['judul'] = "Halaman Berita";
        // $data['tampil_kategori'] = $this->berita->getAllKategori();
        // $data['tampil_wartawan'] = $this->berita->getAllWartawan();
        // $data['tampil_berita_join'] = $this->berita->getBeritaJoin();
        $this->tampil_halaman_berita();

在这里，您需要结合使用class Class_B: UIViewController,UpdateBeneficiaryProtocol { var class_a = Class_A() override func viewDidLoad() { super.viewDidLoad() class_a.myprotocolDelegate = self; } func doGetUpdateInfo(value1: String, value2: String) { print("not calling****") } } 和PASS BY REFERENCE概念来解决问题

尝试我的代码进行测试，让我知道您看到了什么？

-First load model in your tampil_halaman_berita() method
-get data using Model and return data
-then call first method to another method
