Question

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()
{

}

/**

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

        } 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);

当我进入我的kansasoutlawwrestling.com/kowmanager页面时，使用以下代码我得到一个白色的屏幕，但如果我去登录页面是kansasoutlawwrestling.com/kowmanager/login并登录然后我得到一个PHP错误被遇到

实际上@Pekka，tank_auth使用语言库，所以句子不存在，但是对句子的英文版本的引用。您要查找的行就在文件$data['login_by_email'])) { // success

中的controllers/auth.php之后

它使用auth控制器内部的_show_message()函数。该函数在闪存会话数据中设置消息，然后将您重定向到主auth视图（显示存储在闪存中的消息）。您可以使用简单的redirect('myControlPanel');替换此行并且您会没事的。或者做我做的事情并将它们返回到将它们重定向到登录页面的页面。

希望有所帮助，最大

添加数据阵列以进行重定向
