I have an app called static HTML (https://apps.facebook.com/static_html_plus/?ref=ts) installed on a page of mine..
I want to be able to access getSignedRequest() to pass data through the URL in facebook using app_data.. (I want to be able to pass an item id to activate a JS item in the iframe.. in essence allowing me to link to an expanded JS feature in the page)
The issue is that i am recieving NULL from getSignedRequest(); I am not sure if the app I am using (mentioned above : static HTML) is stopping the information from getting passed through to my iframe.
If you are unfamiliar with this app, it allows you to put HTML/CSS/JS to embed an iframe.
On the hunch that it is the app that is stopping the propagation of the facebook data to my iframe, I have attempted to follow SEVERAL tutorials, both video and written that try to create a facebook iframe by creating a custom app.. none have worked, and i have not been successful in even adding a BASIC TAB to any of my pages..
I am about to give up on this facebook thing as every tutorial I have found has a completely different looking interface or set of instructions then what is ACTUALLY available on the facebook developers page..
Does anyone have a CLEAR UP-TO-DATE, non-facebook written walk-through, or atleast know if my use of the static HTML app is what is causing me to recieve null in my getSignedRequest()?
Here is my php code in the iframe i embed in the static HTML app, incase you think the error is in there somewhere.
require 'facebook.php';
//facebook signed app_data
$app_id = "xxxxxx";
$app_secret = "xxxxxxxxxxx";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
// Get contents of signed request
$signed_request = $facebook->getSignedRequest();
Any help would be nice. I have wasted 2 nights on this crap.
.html files cannot accept HTTP POSTs unless the web-server is configured to accept this verb. However, the only way to get at the post parameters is with server-side code and cannot be done clientside.
