Php CodeIgniter新闻教程删除

我正在使用CodeIgniter，已经完成了新闻教程。我试图在新闻部分添加一个删除和更新按钮。我已经在stackoverflow上看到了你关于本教程中删除按钮的帖子，但我仍然无法让它工作

这是我在你的帖子中使用的代码

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();
}

public function set_news()
{
$this->load->helper('url');

$slug = url_title($this->input->post('title'), 'dash', TRUE);

$data = array(
    'title' => $this->input->post('title'),
    'slug' => $slug,
    'text' => $this->input->post('text')
);

return $this->db->insert('news', $data);
 }


public function delete_news($id) {
$this->db->delete('news', array('id' => $id));
}

}





 CONTROLLER - 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'] = $this->news_model->get_news($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');
}
 }


   public function delete($id) {
   $this->news_model->delete_news($id);
   $this->load->helper('url');
   redirect('/www.shelim786.co.uk/CodeIgniter/news');
}




}




VIEWS - index.php 

<?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>
<p><a href="news/delete <?php echo $news_item['slug'] ?>">delete article</a></p>

<?php endforeach ?>

and ROUTING

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

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

我遇到的问题是www.shelim786.co.uk/CodeIgniter/index.php/news上的新闻文章 单击“删除”按钮时不删除

如果你能帮助我，我将不胜感激

谢谢

链接中“删除”一词后没有斜杠。您的链接会显示类似

http://www.shelim786.co.uk/CodeIgniter/index.php/news/delete 6

。注意“delete”后面的空格吗

在您看来，将“删除文章”链接行更改为此

<p><a href="news/delete/<?php echo $news_item['slug'] ?>">delete article</a></p>

请注意“delete”后的斜杠？

您应该重定向删除链接删除新闻功能

不删除功能因为删除查询写在那里

我已经将删除文章链接更改为

，它出现了一个404错误，文章仍然不删除。有什么我做错了吗？控制器的“新闻”一词在链接中重复出现。这是因为在分配删除链接时使用的是相对路径。请尝试删除链接<代码>。我假设您已打开url帮助程序。事实上，我建议您使用

site\u url（）

来分配所有链接，包括查看链接。我花了相当长的时间来找出分配链接的致命错误：调用未定义的函数site_url（）在第8行的/customers/5/f/b/shelim786.co.uk/httpd.www/CodeIgniter/application/views/news/index.php中，这是我在将链接分配到时遇到的错误。我也是CodeIgniter的新手，这是我第一次使用它，所以我不确定如何打开TinyUrl。它们都在手册中。对于url帮助程序，请查看。或者，您可以打开

应用程序/autoload.php

，每次都将“url”添加到自动加载url帮助程序的帮助程序数组中。我强烈建议您至少阅读一到两次整个CodeIgniter手册。他们拥有MVC框架中最好的手册之一
