Facebook login v navigation

Dobrý den, potřeboval bych pomoc s FB loginem. Potřeboval bych dát FB login do navigation, ale hlásí mi to chybu Undefined variable: fbLink. Já ho mám danej zvlášť v jiné stránce, ale nejde mi to dát do navigation.

Takhle vypadá BasePresenter:

<?php

namespace App\Presenters;

use Nette;

abstract class BasePresenter extends Nette\Application\UI\Presenter
{
        const CSS_PATH = PUBLIC_HTML_PATH . "/css/all-min.css";
        const JS_PATH = PUBLIC_HTML_PATH . "/js/all-min.js";

        public function startup()
        {
            parent::startup();

            if($this->getName() != "Unlogged" && !$this->getUser()->isLoggedIn())
            {
                $this->redirect('Unlogged:login');
            }
        }

        public function actionLogout()
        {
            $this->getUser()->logOut();
            $this->redirect("Unlogged:default");
        }

        public function beforeRender()
        {
            $this->template->productionMode = \Tracy\Debugger::$productionMode;
            $this->template->jsVersion = filemtime(self::JS_PATH);
            $this->template->cssVersion = filemtime(self::CSS_PATH);
        }
}

a takhle UnloggedPresenter:

<?php

namespace App\Presenters;

use App\Model\User;
use Facebook\Facebook;
use Nette\Application\UI;

class UnloggedPresenter extends BasePresenter
{
    /** @var string[] */
    private $config;

    /** @var User */
    private $user;

    /** @var Facebook */
    private $fb;

    /**
     * @param string[] $config
     * @param User $user
     * @param Facebook $fb
    */

    protected function createComponentRezervace()
    {
        $form = new UI\Form;
        $form ->addText("vyhledat", "vyhledat");
        return $form;
    }

    public function __construct($config = null, User $user)
    {
        $this->config = $config;
        $this->user = $user;
        $this->fb = new Facebook($config);
        //\Tracy\Debugger::barDump($this->user->getUserByEmail("nicola.zemanova25@gmail.com"));
    }

    public function renderDefault()
    {

    }

    public function actionLogin()
    {
        if($this->getUser()->isLoggedIn())
        {
            $this->redirect(":default");
        }

        $helper = $this->fb->getRedirectLoginHelper();
        $accessToken = $helper->getAccessToken();

        if($accessToken)
        {
            $response = $this->fb->get('/me?fields=id,name,email', $accessToken);
            $user = $response->getGraphUser();

            $existing = $this->user->getUserByEmail($user['email']);

            if($existing)
            {
                $existing = $this->user->updateUser($existing['id'], $accessToken);
            }
            else
            {
                $existing = $this->user->addUser("facebook", $accessToken, $user['email'], $user['name']);
            }

            $this->getUser()->login(new \Nette\Security\Identity($existing['id'], null, $existing));
            $this->redirect("Profile:default");
        }

        $permissions = ['email'];
        $returnUrl = $this->getHttpRequest()->getUrl()->baseUrl . "prihlaseni";
        $this->template->fbLink = $helper->getLoginUrl($returnUrl, $permissions);
    }
}

odkaz na ten FB login:

<div class=„modal-body“>
<a href=„{$fbLink}“> Přihlásit se přes Facebook
 </a>
