   To prevent XSS the following PHP **functions for printing are forbidden: echo, print() and <?=**. Instead use ``p($data)`` for printing your values. Should you require unescaped printing, **double check for XSS** and use: ``print_unescaped($data)``.

   Templates **must not contain database queries**! All data should be passed to the template via ``$template->assign($key, $value)``.
