codeigniter - CodeIgniter路由404错误

Question

跟着CI News Tutorial

我只做新闻部分，所以我将默认 Controller 更改为“新闻”

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

现在，“查看文章” anchor 生成了404错误。将默认值更改为:

 $route['default_controller'] = 'welcome';

创建正确的路径。我应该如何更改路由器以使用新闻？

没有自定义配置，或使用.htaccess。

从config.php中:

$config['base_url'] = 'http://frameworks:8888/ci_site_tut/';

$config['index_page'] = 'index.php';

    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'];

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

    public function create()
    {
        $this->load->helper('form');
        $this->load->library('form_validation');

        $data['title'] = 'Create A News Item';

        $this->form_validation->set_rules('title', 'Title', 'required');
        $this->form_validation->set_rules('text', 'Text', 'required');

        if ($this->form_validation->run() === FALSE) 
        {
                $this->load->view('templates/header', $data);
                $this->load->view('news/create');
                $this->load->view('templates/footer');
        } else {


            $this->news_model->set_news();
            $this->load->view('news/success');

        }



    }

}

解决方案:

自动加载网址帮助器:

$autoload['helper'] = array('url');

更新路线:

$route['default_controller'] = 'news';
$route['404_override'] = 'errors/page_missing';
$route['news/create'] = 'news/create';
$route['news/(:any)'] = 'news/view/$1';
$route['news'] = 'news';

在views / news / index.php中更新了URL:

<p><a href="<?php echo site_url('news/' . $news_item['slug']); ?>">View Article</a></p>  

Answer 1

看来您没有在view方法中的任何地方设置$ new_item ['slug']。在加载 View 之前，请在view方法中执行'print_r($data['news_item'])，以查看是否实际设置了子弹。

如果您确定自己是，请确保url帮助程序已自动加载，然后尝试在 View 中将其用作您的url。

<a href="<?php echo site_url('news/'.$news_item['slug']); ?>">View article</a>
