Facebook apps: Redirect to canvas iframe to URL within app (not main app page) -


i'm using facebook php sdk; setting app on facebook. need app run within canvas only, if user goes url, example: http://{site_url}/fbapp/index.php?this=that&that=this&etc=1

i want to: a) redirect using javascript canvas page (ie. http://apps.facebook.com/appname/) , b) iframe must go directly page within app (ie. index.php?this=that&that=this&etc=1)

i've googled moon not getting anywhere!

any ideas??

i've tried this:

var currlocation = location.href; if ( window.self === window.top && !currlocation.match('facebook') ) { location.href='https://www.facebook.com/dialog/oauth?client_id=<?= $facebook->getappid() ?>&redirect_uri=<?= $site_url; ?>?<?= $_server['query_string']; ?>'; }

it results in indefinite redirect loop between site , facebook.

instead of -

location.href='https://www.facebook.com/dialog/oauth?client_id=getappid() ?>&redirect_uri=?';

use-

header("location: canvas_url"); exit;
