Validate function for the Shorten form. It's hard to really figure out what a valid URL is. We might reasonably expect http://example.com, https://example.com, www.example.com, or even just example.com to be correctly shortened by respective services. So instead of dealing with this logic ourselves, we just check that there is at least a period in the string, because there must be a TLD, and we check length.

    if (!strpos($url, '.', 1)) {
      form_set_error('url', t('Please enter a valid URL.'));
    }
  }
  else {
    form_set_error('url', t('Please enter a valid URL.'));
  }
