I read the Facebook dev info on how to make a request (located here) but I don't exactly understand what it does. Here's what I'd like to do. I'm using PHP and javascript.
I want a logged in user to send a request to a specific URL (with parameters attached) to multiple Facebook users (users who are already signed up for my site). Also, I need to be able to get the users that they selected and save them in the database, because only those users will have access to the URL that they're being invited to.
Are there any suggestions on how I can accomplish this?
