Question

我删除了coneigniter2中的一行，但它需要404页面（找不到您请求的页面。）

这是我的代码

Controler Post

 class Posts extends CI_Controller{


public function index(){
 $data['title'] = 'Ultimos Post';
  $data['posts'] = $this->Post_model->get_posts();
   $this->load->view('templates/header');
    $this->load->view('posts/index',$data);
     $this->load->view('templates/footer');
 }
   ...

   public function delete($id){
      //apagar post pelo id
         $this->Post_Model->delete_post($id);
          redirect('posts');

   }}

发布模型

 class Post_model extends Ci_Model{
  ...

    public function delete_post($id) {

              $this->db->where('id',$id);
                $this->db->delete('posts');

        }}

在View.php中

<?php echo form_open('/posts/delete/'.$post['id']);?>  
<input type="submit" value="Delete" class="btn btn-danger" name="delete">

routes.php文件

$route['posts/create'] = 'posts/create';
$route['posts/(:any)'] = 'posts/view/$1'; 
$route['posts'] = 'posts/index'; 
$route['default_controller'] = "pages/view";
$route['(:any)'] = 'pages/view/$1';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

Answer 1

删除重定向帖子后，哪个调用Posts控制器的索引功能。你的问题帖子控制器索引方法，请分享该方法或亲自检查。

Answer 2

根据您的配置，posts/delete/2路由到posts/view/delete/2。将您的routes配置更改为以下代码：

$route['posts/create'] = 'posts/create';
$route['posts/delete/(:num)'] = 'posts/delete/$1';
$route['posts/(:any)'] = 'posts/view/$1'; 
$route['posts'] = 'posts/index'; 
$route['default_controller'] = "pages/view";
$route['(:any)'] = 'pages/view/$1';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

Answer 3

替换此代码

<强>控制器

class Posts extends CI_Controller{
...
    public function delete(){
        $id = $this->input->post('id');
        $this->Post_Model->delete_post($id);
        redirect('posts');
    }
}

<强>模型

class Post_model extends Ci_Model{
...
    public function delete_post($id) {
        $this->db->where('id',$id);
        $this->db->delete('posts');
    }
}

查看

<?php echo form_open('/posts/delete'); ?> <input type="hidden" name="id" value="<?php echo $post['id']; ?>" /> <input type="submit" value="Delete" class="btn btn-danger" name="delete"> </form>

通过在控制器和路径

控制器

$route['posts/delete/(:num)'] = 'posts/delete/$1'

Route.php
