我是 code igniter 的新手，我正在开发简单的登录系统，我正在使用 xampp，我在文件夹 code/中上传了 code igniter，以下是 mvc 中的代码

Controller 登录.php

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

  class Login extends CI_Controller
     {

 public function __construct()
 {
      parent::__construct();
      $this->load->library('session');
      $this->load->helper('form');
      $this->load->helper('url');
      $this->load->helper('html');
      $this->load->database();
      $this->load->library('form_validation');
      //load the login model
      $this->load->model('login_model');
 }

 public function index()
 {
      //get the posted values
      $username = $this->input->post("txt_username");
      $password = $this->input->post("txt_password");

      //set validations
      $this->form_validation->set_rules("txt_username", "Username", "trim|required");
      $this->form_validation->set_rules("txt_password", "Password", "trim|required");

      if ($this->form_validation->run() == FALSE)
      {
           //validation fails
           $this->load->view('login_view');
      }
      else
      {
           //validation succeeds
           if ($this->input->post('btn_login') == "Login")
           {
                //check if username and password is correct
                $usr_result = $this->login_model->get_user($username, $password);
                if ($usr_result > 0) //active user record is present
                {
                     //set the session variables
                     $sessiondata = array(
                          'username' => $username,
                          'loginuser' => TRUE
                     );
                     $this->session->set_userdata($sessiondata);
                     redirect("index");
                }
                else
                {
                     $this->session->set_flashdata('msg', '<div class="alert alert-danger text-center">Invalid username and password!</div>');
                     redirect('login/index');
                }
           }
           else
           {
                redirect('login/index');
           }
      }
 }
 }?>

模型是 login_model.php

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

 class login_model extends CI_Model
      {
   function __construct()
        {
      // Call the Model constructor
      parent::__construct();
         }

 //get the username & password from tbl_usrs
   function get_user($usr, $pwd)
    {
        $sql = "select * from tbl_usrs where username = '" . $usr . "' and password = '" . md5($pwd) . "' and status = 'active'";
      $query = $this->db->query($sql);
      return $query->num_rows();
 }
  }?>

View是login_view

   <!DOCTYPE html>
   <html>
     <head>
 <meta charset="utf-8">
 <meta name="viewport" content="width=device-width, initial-scale=1.0">

      <?php echo form_close(); ?>
      <?php echo $this->session->flashdata('msg'); ?>
               </div>
             </div>
             </div>

          <!--load jQuery library-->
       <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

      </html>

我使用的IN配置 $config['index_page'] = '';在我使用的 route $route['default_controller'] = '登录'; $route['404_override'] = ''; $route['translate_uri_dashes'] = FALSE;在访问 localhost/code/时它工作正常但是当单击登录按钮时它将转到 url http://localhost/code/localhost/login/index并显示找不到对象 ERROR 404

最佳答案

打开 application/config/config.php 并设置您的 base_url()。例如:$config['base_url'] = 'http://localhost/code/';

在 /code 文件夹(应用程序和系统文件夹所在的位置)下创建 .htaccess 文件，如下所示:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
