我想获取已登录用户的ID，然后打印出以下行
echo "<pre>"; print_r($this->session->userdata());
结果如下：

以下代码是会话设置的地方
if($auth_driver->login($input['email'], $input['password'], $input['remember']))
{
$userdata = $this->user->row(array('user_email'=>$input['email']));
// if user is not existed, create it
if (!is_object($userdata)) {
// create the user and make it active
$newuser = new User_model;
$newuser->user_type = User_model::TYPE_USER;
$newuser->user_name = $input['email'];
$newuser->user_email = $input['email'];
$newuser->user_pass = $input['password'];
$newuser->user_mobile = '';
$newuser->user_avatar = '';
$newuser->user_status = User_model::STATUS_ACTIVE;
$newuser->save();
// load the user info
$userdata = $this->user->row(array('user_email'=>$input['email']));
}
}
if(isset($userdata) && is_object($userdata) && isset($userdata->user_id)) {
// check if the account is active
if($userdata->user_status == User_model::STATUS_ACTIVE) {
$this->session->set_userdata('userdata', $userdata);
redirect('/User/Dashboard');
} else {
unset($userdata);
set_message('activate_your_account', 'error');
redirect('/Auth/Activate');
}
} else {
set_message('wrong_email_or_password', 'error');
}
redirect('/Auth/Login');
}
我希望您帮助我访问userdata中的user_id
提前致谢

根据您的会话转储：
$user_id = $this->session->userdata('user_id');
