我正在尝试创建一个用户页面，我可以在其中显示一个表，其中包含从数据库中获取的用户数据。当我运行该文件时，我收到了404错误。如果您能查看我的代码，我将非常感激。
display_user.php
<?php
class display_user extends CI_Controller
{
public function index()
{
//load the database
$this->load->database();
//load the model
$this->load->model('DisplayModel');
//load the method of model
$data['h']=$this->select->select();
//return the data in view
$this->load->view('user_view', $data);
}
public function signin()
{
//$this->load->view('includes/header');
$this->load->view('user_view');
//$this->load->view('includes/footer');
}
public function validate()
{ $this->load->helper('email');
$this->load->library('form_validation');
$this->load->model('admin_model');
$query=$this->DisplayModel->signin_control();
if($query)
{ $admin_id = $this->DisplayModel->get_admin_id_from_username();
$admin = $this->DisplayModel->get_admin($employee_id);
$data = array('id'=>$employee_id, 'email' =>$this->input->post('email') , 'is_logged_in'=>true);
$this->session->set_userdata($data);
$this->load->view('admin_view',$employee);
}
else
{
$this->index();
}
}
public function signup()
{
$this->load->view('view_signup',array('error' => ' ' ));
}
}
?>
DisplayModel.php
<?php

// Call the Model constructor
parent::__construct();
