會話變量不起作用codeigniter（PHP）

Question

我的會話有問題。 我沒有在本地主機或其他服務器上遇到此問題。 只有one.com有此問題。 定義了會話並將其設置為指定的會話文件夾，但是刷新頁面時似乎缺少該會話。

登錄頁面代碼

$submitted = $this->input->post('email');
    $admin_logged_in = $this->session->userdata('admin_logged_in');
    if($admin_logged_in != true){
        if($submitted != ""){
            $email = xss_clean($this->input->post('email'));
            $password = xss_clean($this->input->post('password'));
            $id = $this->Admin_Model->admin_log($email,$password);
            if($id == 1){
                $user = $this->Admin_Model->get_admin($email);
                $data['user'] = $user;
                $session_data = array(
                    'admin_id'  => $user->id,
                    'admin_email'     => $user->email,
                    'admin_logged_in' => true
                );
                $this->session->set_userdata($session_data);
                redirect('admin');
            }else{
                $data['error'] = array( 'type' => 'error', 'message' => 'Account information is incorrect.');
                $this->load->view('admin/login',$data);
            }
        }else{
            $this->load->view('admin/login',$data);
        }
    }else{
        $user_id = $this->session->userdata('admin_id');
        $user = $this->Admin_Model->get_admin_id($user_id);
        $data['user'] = $user;
        $this->load->view('admin/admin_home',$data);
    }

İndex頁面代碼（登錄后的下一頁）

$admin_logged_in = $this->session->userdata('admin_logged_in');
    if($admin_logged_in == true){
        $user_id = $this->session->userdata('admin_id');
        $user = $this->Admin_Model->get_admin_id($user_id);
        $data['user'] = $user;
        $this->load->view('admin/admin_home',$data);
    }else{
        $this->load->view('admin/login',$data);
    }

會話配置

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = 'ci_sessions'; // Or sys_get_temp_dir()
$config['sess_match_ip'] = FALSE; // Or True
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE; // Or True

我已經感謝能夠找到解決方案的朋友。

Answer 1

我已經很長時間沒有寫回復了，但是也許我滿足其他朋友的需求。

$config['sess_driver'] = 'files'; 
$config['sess_save_path'] = sys_get_temp_dir(); 

Answer 2

您需要設置會話保存路徑，例如

$config['sess_save_path'] = APPPATH . 'cache/sessions/'; 

因為您有$config['sess_driver']作為文件

然后$autoload['libraries'] = array('session');
