Question

我目前正在学习CodeIgniter的方法，我需要一些关于本教程的视图新闻部分的帮助。它显示了404页面。我的网站是Tristans.tk。点击新闻，然后点击其中一个标题。这是我的代码：

这是我的模特：

class News_model extends CI_Model{

    public function __construct(){
        $this->load->database();
    }
    public function get_news($ID=FALSE){
        if($ID===FALSE){
            $query=$this->db->order_by("post_time", "DESC")->get('news');
            return $query->result_array();
        }
        $query=$this->db->get_where('news',array('ID'=>$ID));
        return $query->row_array();
    }
}

这是新闻控制员：

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);
        $this->load->view('templates/footer');
    }
    public function view($ID){
        $data['news_item'] = $this->news_model->get_news($ID);

        if (empty($data['news_item'])){
            show_404();
        }
        $data['title'] = $data['news_item']['title'];

        $this->load->view('templates/header', $data);
        $this->load->view('news/view', $data);
        $this->load->view('templates/footer');
    }

}

这是观点：

<?php
print_r($news_item);
echo '<h2>'.$news_item['title'].'</h2>';
echo $news_item['content'];
?>

路线：

$route['news/(:any)'] = 'news/view/$1';
$route['news'] = 'news';
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';

新闻索引：

<?php foreach ($news as $news_item): ?>
<div class='post'>
    <h1 class='post_title'><a href="news/view/<?php echo $news_item['ID'] ?>"><?php echo $news_item['title'] ?></a></h1>
    <p class='post_time'><?php echo $news_item['post_time'] ?></p>
    <p class='post_content'><?php echo $news_item['content'] ?></p>
    <span class='comment_link'><a href="news/view/<?php echo $news_item['ID'] ?>">Comment</a></span>
    </div>
<?php endforeach ?>

Answer 1

尝试更改此

$route['news/(:any)'] = 'news/view/$1';

到

$route['news/(:any)'] = 'news/$1';

使用此：$route['news/(:any)'] = 'news/view/$1';，

如果您访问yourdomain.tk/news/view/1

实际上您访问yourdomain.tk/news/view/view/1

Answer 2

更改

$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';

$route['news'] = 'news';
$route['news/create'] = 'news/create';
$route['news/show/(:any)'] = 'news/show/$1';

到

$route['news'] = 'news';
$route['news/create'] = 'news/create';
$route['news/show/(:any)'] = 'news/show/$1';

$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';

祝你好运

CodeIgniter新闻/视图不起作用，第404页
