您好我正在编写登录和注册模块 我发现了像这样的会话错误。 首先我登录然后关闭页面。之后，我重新打开页面并输入路径网址，这将发生.....，
<?php ///////////////view/header.php///////////
if($this->session->userdata('is_logged_in'))
{
echo "Welcome!, " . $this->session->userdata('username');
echo anchor('login/logout','Sign Out') ."</span>";
}
else
{
echo anchor('login','Log in');
echo anchor('register/index','Register') ;
}
?>
登录控制器
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Login extends CI_Controller
{
public function __construct()
{

$this->load->library(array('form_validation','session'));
}
public function index()
{
$this->load->view('header');
$this->load->view('regislogin/loginform');

if($this->form_validation->run()) //==TRUE
{
$data = array(
'username' => $this->input->post('username'),

$this->session->set_userdata($data);

请检查您的会话是否有效， 您还在控制器和注销上添加适当的条件。 最好在钩子中添加一个条件，这样你就不必为每个控制器编写它。 您还可以提供一些代码片段来查看更多内容。
答案 1 :(得分：1)
我导入了你的代码并且它正在运行它应该是。 请做下面的事情 1.添加一个空数组$ data = array（）;在index函数中的Register.php（controller）里面。 2.在登录控制器内部功能userPage中，Else条件添加一行以在登录页面上重定向
public function userPage()
{
if($this->session->userdata('is_logged_in')) //if==true
{
$this->load->view('header');
$this->load->view('regislogin/success');
}
else
{
redirect('login');
}
}
您有任何疑虑，请在收到错误的地方分享您的页面名称。

好的，我解决了。 在文件夹路径config / config.php中 设置这个 $ config [＆＃39; base_url＆＃39;] =＆＃39; http：//＆＃39;。$ _ SERVER [＆＃39; HTTP_HOST＆＃39;]。＆＃39; / foldername＆＃39;; < / p>
