Question

Ive currently setup a Facebook tab on my Facebook fanpage.

It seems im not able to get any vars defined in my tab app url like:

http://www.facebook.com/pages/myApp/177845772355947?sk=app_379422318804869&share=var_i_want_to_pass_via_GET_to_PHP

So in my PHP im simply trying to do a

echo $_GET["share"];

However it seems I cant pass on anything from the tab app url.

I did the same thing with my canvas page url like:
http://apps.facebook.com/myCanvasApp/?share=var_i_want_to_pass_via_GET_to_PHP

And here I can easily echo it out.

Any ideas?

You need to use the app_data field in the signed_request.

Here’s two pages on Facebook’s Developer site that cover what you want.
