Redirect after photo upload and avoid showing graph api endpoint response - PHP SDK 3

I'm trying to build an iframe app for my work through which a user can upload a photo to their photos.

I have managed to get the photos to upload - BUT once the photo is uploaded, my app just shows the new photos ID (endpoint response) and removes everything else from the iframe (as shown in the second link below).

I want to be able to redirect to a success page or even just back to my app without showing this 'endpoint response'.

I have been using this tutorial to get me to where I am: http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development-php-sdk开发者_如何学编程-3-0/

and

https://developers.facebook.com/blog/post/498/

for the upload.

This is the first time I have attempted to build a Facebook app and I am really struggling, any help would really be appreciated.

Cheers,

Andy

If the question is how you can redirect a page a condition is true (i.e. the picture has been uploaded), header("Location: url") might be the answer. When using header location there are two concerns:

1) Make sure that the url you are redirecting to is absolute (including http://lalalala/llala/la)

and

2) Nothing can be outputted before your header. Consider this example:
