Message: Undefined variable: news
Filename: news/index.php
Line Number: 1
A PHP Error was encountered

我按照CodeIgniter网站中的用户指南进行操作。
这些是我使用的代码：
News_model.php
<?php
class News_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_news($slug = FALSE)
{
if ($slug === FALSE)
{
$query = $this->db->get('news');
return $query->result_array();
}
$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}
}
News.php
<?php
class News extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('news_model');
}
public function index() {
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
public function view($slug) {
$data['news_item'] = $this->news_model->get_news($slug);
if(empty($data['news_item'])) {
show_404();
}
$data['title'] = $data['news_item']['title'];
}
}
index.php （VIEW）
<?php foreach ($news as $news_item): ?>
<h2><?php echo $news_item['title'] ?></h2>
<div id="main">
<?php echo $news_item['text'] ?>
</div>
<p><a href="news/<?php echo $news_item['slug'] ?>">View article</a></p>
<?php endforeach ?>
view.php
<?php
echo '<h2>'.$news_item['title'].'</h2>';
echo $news_item['text'];
echo "Hello";
为什么我收到错误的任何想法？非常感谢帮助。感谢。
更新
我删除了渲染功能。现在，当我去查看新闻时，它是空的，没有显示任何记录。
