i have this app that asks the user to take a quiz and after that quiz (on the result page), the user has to like the page to continue using the app.
so, i need to retrieve $_REQUEST["signed_request"] on that page.
the problem is.. i can print $_REQUEST["signed_request"] only on the index page, but NOT on the result page…
and, by the way, when i click on the “like” button of the page, it redirects me on the index (again) instead of staying on the result page.. causing the user to begin the quiz again!
what should i do?
Store whether or not the user has liked the page in a session variable and access it in the second page
