Question

我在功能profile()中遇到问题。在这种方法中，我使用session从电子邮件中获取数据。

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，刷新后会成为当前的会话数据。 enter image description here 上次会议数据

刷新后显示当前会话

我的控制器文件是admin.php。

admin.php的

<?php 
class Admin extends CI_Controller{

    function __construct(){
        parent::__construct();

        // Load form helper library
        $this->load->helper('form');

        $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

在logount而不是unset数据之后尝试以下操作，完全破坏会话

$this->session->sess_destroy();

为什么我在codeiginitor中获取当前会话的先前会话数据，即使在销毁前一个会话之后也是如此
