<?php 

use Holabs\TOTP;
use Nette\Application\UI\Form;
use Nette\Utils\ArrayHash;

class SignPresenter extends BasePresenter
{

	/** @var TOTP @inject */
	public $totp;


	public function actionDefault() {
		if (!isset($_SESSION['totp'])) {
			// Store in Database or file is better
			// Every time you generate secret, your use have to delete old and add new in APP
			$_SESSION['totp'] = $this->totp->generateSecret();
		}

		$secret = $_SESSION['totp'];

		$this->template->qr = $this->totp->getQRUrl($secret);
		$this->template->secret = chunk_split($secret, 4, ' ');
		$this->template->status = '';
	}


	/**
	 * Sign-up form factory.
	 * @return Form
	 */
	protected function createComponentSecondFactor()
	{
		$form = new Form();

		$form->addText('code', 'Code', 6)
			->setRequired('Code is required');
		$form->addSubmit('submit', 'Send');

		$form->onSuccess[] = function ($form, ArrayHash $values) {
			if ($this->totp->verify($_SESSION['totp'], $values->code)) {
				$this->template->status = 'Code OK';
			} else {
