Facebook Request Dialog is used to invite friends to start using an application, or to send requests for some specific action to application users. It is implemented in two forms: as a button or as a link, on which user has to click to open the request dialog. There is also an option to open it automatically on page load.

This class is a member of Facebook Connect PHP Toolkit. To see all classes from the toolkit, please look at the Facebook Connect Graph API classes.
