I am migrating our existing wss 3.0 site to sharepoint Foundation 2013. Everything is complete but this one item.
We have a Filemaker DB in house that also has a custom PHP frontend. I have a page created in SP 2013 with a Page Viewer Web part that i embed the URL in for the PHP - Database website. I have always used the following url to grab the currently logged in user from sharepoint and pass it to my php for user tracking.
http://webaddress/database/start.php?userName=_LogonUser_
This has always worked is WSS 3.0 - it would pass the "domain\username" to my php script that would parse it.
Now with SP 2013 - when i run this same URL - it returns nothing. I am at a loss. I have tried various fixes that i have run across through googling - but my coding experience is null and as much as i have read, this should still work?
