我已经实现了Codeigniters cart类,它自动启用会话(我从文档中收集的内容)并将会话数据存储到db中的ci_sessions表中。
但是,当我以用户身份注销时,会话仍保留在数据库中。如果重新登录,旧会话将保留,并创建新会话。它是否正确?在登录时,我从来没有真正检查ci_sessions表中的现有会话,这是我需要实现的东西还是codeigniter自动处理的东西?
这是我登录和注销的功能,我取消设置会话变量,但这本身并不会从数据库中删除会话。
class User extends CI_Controller {
function __construct() {
parent::__construct(); // Don't forget to call the parent constructor in this method
}
public function dashboard() {
$this->load->view('template/header');
$this->load->view('user/dashboard');
$this->load->view('template/footer');
}
public function index()

$this->load->view('template/header');
$this->load->view('landing_page');
$this->load->view('template/footer');
}

$this->load->view('template/header');
$this->load->view('user/register');
$this->load->view('template/footer');
}

$this->load->view('template/header');
$this->load->view('user/login');
$this->load->view('template/footer');
}

的config.php

$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
在上面添加了我的config.php。我正在使用数据库作为会话驱动程序。

您错误地在session
中设置了login controller
。这就是session
剩余的原因。
我假设您已在application/config/autoload.php
下自动加载会话。
您创建的数组是正确的。
$user_data = array(
'user_id' => $user_id,
'email' => $email,
'logged_in' => true
);
接下来将其设置为会话,如下所示。
$this->session->set_userdata('login_session',$user_data);
//你错了。
设置会话后,将用户重定向到信息中心或主页。
要log out
用户,请使用以下代码
if($this->session->userdata('login_session'){
$this->session->unset_userdata('login_session');
// Set message
$this->session->set_flashdata('user_loggedout', 'You are now logged out');
redirect('user/login');
}else{
redirect('user/login');
}
现在,每当用户打开您的网站时,请检查用户的登录会话是否处于活动状态。
在构造函数下添加此代码。
class Dashboard extends CI_Controller{
public function __construct(){
parent::__construct();
if(!($this->session->userdata('login_session'))){
redirect('user/login','refresh');
}
}
同样,在您的登录控制器中,检查登录会话是否处于活动状态。
class Login extends CI_Controller{
public function __construct() {
parent::__construct();
if($this->session->userdata('login_session')){
redirect('user/dashboard','refresh');
}
}
}
编辑 - 如果您在单个控制器中同时使用这两种方法,则使用此代码
class User extends CI_Controller{
public function __construct() {
parent::__construct();
if(!$this->session->userdata('login_session')){
redirect('login','refresh');
}
}
public function login(){
$this->load->view('login_view');
}
public function dashboard(){
//since in controller I'm checking the session, you need not have to check it in the dashboard.
$this->load->view('dashboard_view');
}
}
希望这可以帮到你。

当他们点击退出时,将他们发送到destroys the session。
的控制器/方法$this->session->sess_destroy();
这会使会话无效并阻止您进一步访问它。 CodeIgniter会自己清理数据库中过期的会话,你不需要进行垃圾回收。
