In a facebook iframe page (not tab), I'd like to post data to an external API using cURL, but I would prefer if my form page didn't reload.
I'd like to have some jquery ajax happening ("submitting data" message on submission of the form and a success message on success of the curl_exec). I was thinking of creating a hidden iframe with a duplicate form and update values in that form on change events, but i don't know quite how I'd implement that exchange between PHP and jquery.
Is there a better way? Here's the code I'm working on:
UPDATED CODE TO RETURN FALSE -- Does not submit form data.

Currently this will successfully send the data to the external PHP API, but the iframe (or my whole file) reloads on submission (and displays "success" message).
