我在功能profile()中遇到问题。在这种方法中，我使用会话从电子邮件中获取数据。为什么即使在销毁之前的会话之后，我仍然在codeiginitor中获取本届会议的会话数据
当我登录时，显示当前数据。但是当我点击配置文件时，它会显示以前的会话数据，刷新后会变成当前的会话数据。刷新显示当前会话 
我的控制文件是admin.php后 
上次会话数据
。
admin.php的
<?php
class Admin extends CI_Controller{
function __construct(){
parent::__construct();
// Load form helper library
$this->load->helper('form');
//Load foam valodation library
$this->load->library('form_validation');
// Load the model
$this->load->model('adminmodel');
}
public function index(){
// Load our view to be displayed
$this->load->view('admin/login');
}
// Check for Admin login process
public function dashboard(){
// Validate the user can login
$this->form_validation->set_rules('email', 'Email', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
if ($this->form_validation->run() == FALSE) //checking validation
{
if(isset($this->session->userdata['logged_in']))
{
$this->load->view('admin/dashboard');

$result = $this->adminmodel->validate($email,$password);
if ($result) {//if the user credidential is validated
$data = array(
'email' => $this->input->post('email'),

print_r($data);

听起来像一个缓存的问题，如果您需要手动刷新才能看到当前会话数据。刷新不应更改会话数据，它应该在第一次加载时存在。但问题是，第一次加载是否发生，或者页面是否直接来自网络服务器或浏览器的缓存。我建议在页面中添加一个时间戳，如果这样会显示正确的时间并输入错误的数据，以确保页面实际上是在点击配置文件时加载的。 – bardiir
