facebook permissions : How to check if the user has already allowed publish_stream for your app

Question

Hi, wanted to know how to check if the user has already allowed your application to publish on his stream ( to avoid the momentarily popup menu). Currently I'm simply using this javascript

<script>
<!--
Facebook.showPermissionDialog('publish_stream,read_stream');
//-->
</script>

Answer 1

Use Users.hasAppPermission to check if a user has those permissions.

General API: http://wiki.developers.facebook.com/index.php/Users.hasAppPermission

Javascript library: http://developers.facebook.com/docs/?u=facebook.jslib.FB.ApiClient.users_hasAppPermission
