[PHP] Sending Email Notification in Facebook JavaScript API
- by Veera
I'm trying to send a email notification to the user from my Facebook application. I'm trying to use the FaceBook JavaScript API function
notifications_sendEmail(Array recipients, String subject, String text, String fbml, Object onRequestCompleted)
I can understand the first four parameters. But what's the usage of the last parameter 'onRequestCompleted'. The Doc says it's the call back function. But, what if I do not want to execute a call back function? In this case, what will be a valid values to the parameter onRequestCompleted?
