我今天的问题是这样的。成功登录后,我想在重定向时将数据阵列中的user_id发送到控制面板。我这里有很多代码。其中98%是从认证库中编写的代码,我担心如果我现在修补过多,我最终会通过尝试做一件事来破坏别的东西。有什么帮助吗?
class Auth extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->load->library('security');
$this->load->library('tank_auth');
$this->lang->load('tank_auth');
if ($this->tank_auth->is_logged_in()) {
redirect('/cpanel/');
} else {
redirect('/auth/login/');
}
}
function index()
{
}
/**
* Login user on the site
*
* @return void
*/
function login()
{
if ($this->tank_auth->is_logged_in()) { // logged in
redirect('/cpanel');
} elseif ($this->tank_auth->is_logged_in(FALSE)) { // logged in, not activated
redirect('/auth/send_again/');
} else {
$data['login_by_username'] = ($this->config->item('login_by_username', 'tank_auth') AND
$this->config->item('use_username', 'tank_auth'));
$data['login_by_email'] = $this->config->item('login_by_email', 'tank_auth');
$this->form_validation->set_rules('login', 'Login', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean');
$this->form_validation->set_rules('remember', 'Remember me', 'integer');
// Get login for counting attempts to login
if ($this->config->item('login_count_attempts', 'tank_auth') AND
($login = $this->input->post('login'))) {
$login = $this->security->xss_clean($login);
} else {
$login = '';
}
$data['errors'] = array();
if ($this->form_validation->run()) { // validation ok
if ($this->tank_auth->login(
$this->form_validation->set_value('login'),
$this->form_validation->set_value('password'),
$this->form_validation->set_value('remember'),
$data['login_by_username'],
$data['login_by_email'])) { // success
redirect('/cpanel');
} else {
$errors = $this->tank_auth->get_error_message();
if (isset($errors['banned'])) { // banned user
$this->_show_message($this->lang->line('auth_message_banned').' '.$errors['banned']);
} elseif (isset($errors['not_activated'])) { // not activated user
redirect('/auth/send_again/');
} else { // fail
foreach ($errors as $k => $v) $data['errors'][$k] = $this->lang->line($v);
}
}
}
$this->template->set_layout('default')->enable_parser(false);
$this->template->build('auth/login_form', $data);
}
}
编辑:
所以我已经将模型与控制器包括在内但是我得到了这个错误,因为我也包含了模型。

答案 0 :(得分:2)
从我看来,你真正的问题是:
如何获取登录用户ID?
答案:
$this->tank_auth->get_user_id()
这将从会话数据中提取user_id,因此您不必每次都发送该ID,您可以“询问”tank_auth库给您:)
PS:如果这不是您想要的,您可能需要考虑重新提出问题。
为什么这是__construct()?
if ($this->tank_auth->is_logged_in()) {
redirect('/cpanel/');
} else {
redirect('/auth/login/');
}
那个基本上可以阻止你在auth中访问任何操作,然后登录。并且肯定会导致重定向循环
