Question

当我使用正确的信息登录时，我收到以下消息：

注意：未定义的属性：第37行的/var/www/classes/User.php中的stdClass :: $ id
  成功登录！
  User.php中的第37行是以下
  Session :: put（$ this-＆gt; _sessionName，$ this-＆gt; data（） - ＆gt; id）;

此外，在我登录并更新页面并转到/index.php以尝试打印会话后，我什么都没得到。在index.php页面上执行以下命令

echo Session::get(Config::get('session/session_name'));

如果我没有登录并只是转到index.php，我会收到以下消息注意：未定义的索引：第12行的/var/www/classes/Session.php中的用户

的login.php

<?php
require_once 'core/init.php';

ini_set('display_errors', 1);
error_reporting(~0);

if(Input::exists()) {
    if(Token::check(Input::get('token'))) {

        $validate = new Validate();
        $validation = $validate->check($_POST, array(
            'username' => array('required' => true),
            'password' => array('required' => true)
        ));

        if($validation->passed()) {
            $user = new User();
            $login = $user->login(Input::get('username'), Input::get('password'));

            if($login) {
                echo 'Success Login!';
            } else {
                echo 'Login failed';
            }
        } else {
            foreach($validation->errors() as $error) {
                echo $error;
            }
        }
    }
}

    public function find($user = null) {
        if($user) {
            $field = (is_numeric($user)) ? 'id' : 'username';
            $data = $this->_db->get('users', array($field, '=', $user));

            if($data->count()) {
