我是codeigniter的新手。每当我单击“编辑”时，我都会从教程中获取内容。

它链接到..http://localhost/crud/index.php/users/edit/1

我得到了我得到了404 Page not Found。

我认为这只是控制器的uri或分页的问题。会有什么问题？

users.php - 控制器

<?php

if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Users extends CI_Controller {

function __construct()

{

parent::__construct();

#$this->load->helper('url');

$this->load->model('users_model');

}

public function index()

{

$data['user_list'] = $this->users_model->get_all_users();

$this->load->view('show_users', $data);

}
public function add_form()

{

$this->load->view('insert');

}
public function insert_new_user()

{

$udata['name'] = $this->input->post('name');

$udata['email'] = $this->input->post('email');

$udata['address'] = $this->input->post('address');

$udata['mobile'] = $this->input->post('mobile');

$res = $this->users_model->insert_users_to_db($udata);

if($res){

header('location:'.base_url()."index.php/users/".$this->index());

}

}
public function delete_a_user($id)

{

$this->db->where('users.id',$id);

return $this->db->delete('users');

}
public function delete($id)

{

$this->users_model->delete_a_user($id);

$this->index();

}

public function update()

{

$mdata['name']=$_POST['name'];

$mdata['email']=$_POST['email'];

$mdata['address']=$_POST['address'];

$mdata['mobile']=$_POST['mobile'];

$res=$this->users_model->update_info($mdata, $_POST['id']);

if($res){

header('location:'.base_url()."index.php/users/".$this->index());

}

}

}

您有几个错误，首先您必须将“更新”方法重命名为“编辑”。

public function edit($id) {

   $mdata['name']    = $_POST['name'];
   $mdata['email']   = $_POST['email'];
   $mdata['address'] = $_POST['address'];
   $mdata['mobile']  = $_POST['mobile'];

   $res = $this->users_model->update_info($mdata, $id);

   if($res)
      // this is wrong too.. $this->index() execute the index method
      // header('location:'.base_url()."index.php/users/".$this->index());

      // use redirect function like this
      redirect('users/index');

}

您忘记在控制器中添加功能编辑。在您的情况下，它将是这样的：

function edit($id)

{

$mdata['name']=$_POST['name'];
$mdata['email']=$_POST['email'];
$mdata['address']=$_POST['address'];
$mdata['mobile']=$_POST['mobile'];

$res=$this->users_model->update_info($mdata, $id);

...

}

我在您的控制器中看不到名为“编辑”的功能。CI URL 默认的工作方式是，第一段“用户”是控制器，类名（用户）。- 文件和类必须具有相同的名称。URL“edit”的第二部分将是类中函数的名称。在您的情况下，您的 URL 正在查找类“用户”和该类中称为“编辑”的函数，并且“编辑”不存在！

添加这个。

public function edit(){
    // do your stuff here
}

在您的users.php - 控制器中可能是一个函数编辑，例如：

  function edit() {

     $this->user_model->edi_user();
     redirect('http://url.com/user/');


}

在模型中：

public function edit_user(){

$id         = $this->session->userdata('user_id');
$data       = array(
'name'      => $this->input->post('name'), 
'lastname'  => $this->input->post('lastname'), 
);

$this->db->where('id', $id);
$this->db->update('users', $data);         

   }
