在CodeIgniter中获取Hook中的会话数据

Question

我正在使用codeigniter我想使用Hook进行登录验证.这意味着我希望在每个控制器中检查会话数据和登录的时间.因为我在会话中插入了登录时间.如果登录或不登录,那么自从他登录以来的时间.所以我想使用挂钩.我想从数组访问session-> userdata值,但我不知道如何从数组中获取这些值.我想从数组获取记录时间并更新whenevr用户点击或在站点上导航.这是我的代码:

//enter code here
$hook['post_controller_constructor'][] = array(
                           'class'    => 'Authenticate',
                           'function' => 'loginCheck',
                           'filename' => 'authenticate.php',
                           'filepath' => 'hooks',
                           'params'   => array()
                           );

class Authenticate
{

    private $CI;

    function __construct()
    {
        $this->CI =& get_instance();

        if(!isset($this->CI->session)){  //Check if session lib is loaded or not
              $this->CI->load->library('session');  //If not loaded, then load it here
        }
    }

   function loginCheck()
   {

        if(!$this->CI->session->userdata){
            if($this->CI->session->userdata('uid')=="XYZ")
            {
                echo "Valid User"; //it wont get inside this if
            }
        }
    }
}

我有数据:

$this->CI->session->userdata array :
Array ( [session_id] =>afaf... [ip_address] => ::1 [user_agent] => Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.143 Safari/537.36 [last_activity] => 1408553094 [user_data] => [logged_in] => Array ( [Id] => 1 [user_name] => buzz [login_time] => 22:14:54 [uid] => XYZ ) )

我怎么能ID,user_name在钩子里回头？

Answer 1

function loginCheck()
{
    $session_userdata = $this->CI->session->userdata('logged_in');
    if($session_userdata['uid']=="XYZ")
    {
        echo "Valid User"; //it wont get inside this if
    }
}
