Not sure if Joomla has a custom Facebook PHP SDK but the code presented above doesn't match the latest Official Facebook PHP SDK

https://github.com/facebook/facebook-php-sdk

With this being the way to get email permissions

$params = array(
  'scope' => 'publish_stream,email',
  'redirect_uri' => 'http://www.oyeparty.com/bangalore'
);

$loginUrl = $facebook->getLoginUrl($params);
