Can't get proper signed_request info after redirect within FB Page tab App

Initially upon landing on the app, $facebook->getSignedRequest(); gives me the proper info I'm looking for, like info about the current page etc. But then after clicking through links within the app the returned array from $facebook->getSignedRequest() is different. It contains [code] but nothing about if the page is liked etc

How can I resolve this? Is it rather best practice to change pages within the app via parent.location.href ?


Redirects within your app will not receive the signed_request parameter. You'll have to manage saving that data yourself (in the session variable for example).
