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 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/' . $news_item['slug']); ?>">View Article</a></p>
最佳答案
看来您没有在view方法中的任何地方设置$ 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>
