Are there different ways to post to user's wall and ask for permissions?

Question

I've been checking some app, which is configured and loaded as page tab.

This app ask for the corresponding permissions, publish_stream, etc. but the permissions dialog open as a lightbox, without leaving the app/page/tab. Look

After giving permissions, I vote a picture and the app publishes into my wall as if I have written a comment into the post... "I've voted for ... blablabla"

• Am I missing some parameter in the $facebook->api("$user/feed") api call?
• Should I call another api function?

Thanks

Answer 1

I see this as 2 questions:

1.) How to get a lightbox 2.) how to autopost a message or action

1.) The lightbox dialogs are something you can invoke with the js sdk -> FB.ui IF you have basic permissions. The only exception i found was Facebook tab apps! :D

2.) What i can make of the screenshot is just a simple post to a users /[user]/feed on the graph, to achieve this when someone is offline : https://developers.facebook.com/roadmap/offline-access-removal/ ... actions are pretty much the same, except that you post to [user]/actions
