I see the protected function makeRequest which seems like it could be used to publish to a friends wall, but I am not sure the proper way to access it. In my case I would like to use it from a Form's Actions function, using data submitted by the user to publish to someones wall.
These are pretty facebook specific question here, but I'll throw it out just in case somebody knows off the cuff--
In order to publish to a friend's wall I will also need to be granted higher permissions than the module requests by default, yes? I believe this can be done with the set_permissions function, but after setting them how do you re-request the user to authorize them?
You can use FacebookConnect::set_permissions($permissions) to set what permissions the module asks for. Not sure if it works but it should reask the user if your application hasn't got all the permissions required.
