There are two attributes you can use to configure your crossword
<crossword src="path/to/word-list" msg="You win"></crossword>
Note: alternatively you can load a crossword using the “puzzle” parameter in your url
http://<domain>/<install-dir>/?puzzle=<your-puzzle-list>
You may want to allow download of the crosswords only to some of your users.
All you have to do is edit the function user_can_download_pdf in download/index.php, by default this function always return True.
Example
<?php
// download/index.php
function user_can_download_pdf() {
return isset($_SESSION["user_is_logged"]) && $_SESSION["user_is_logged"];
}
