In the instructions for building a serialized php array it says to create a standalone php file that will return the serialized array.  Can I call is_user_logged_in() in this standalone php file? Can I call user_can() in the file? I want to make sure this file is only executed by the wpdatatables plugin and not executed directly from the internet. Maybe a nonce should be supported for security.

I'm trying to use php to provide the data for the tables but I don't  want to create a standalone php file for that (since someone could retrieve data using the standalone php file without logging into the site). I think I have figured out a solution. I can add a filter on wpdatatables_filter_serialized and provide the data in my filter function. The standalone php file will just return an array containing enough information for the filter function to actually retrieve the data.

Thanks, Jon
