404 找不到代码点火器页面 - 404 Page not found Codeigniter

我是codeigniter的新手。每当我单击编辑时，我都会从教程中制作 crud。

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

我得到的是 404 页面未找到。

我认为这只是控制器的 uri 或分页问题。会有什么问题？

用户.php - 控制器

<?php

parent::__construct();

public function index()
{
$data['user_list'] = $this->users_model->get_all_users();
$this->load->view('show_users', $data);

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

public function insert_new_user()

$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);

您忘了在控制器中添加函数编辑。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);
...
}

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');

}

PD：我是阿根廷人，我的英语水平很差。

我在控制器中看不到一个名为"edit"的功能。默认情况下，CI URL 的工作方式是第一段"用户"是控制器，即类名 (Users(。- 文件和类必须具有相同的名称。URL"edit"的第二段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"和该类中名为"edit"的函数，并且"edit"不存在！

添加这个。

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

在您的用户中.php - 控制器可能是一个功能编辑像什么：

  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);         
   }
