Question

I made the authorization and authentication via facebook like here:
http://symfony.com/doc/current/cookbook/security/custom_authentication_provider.html
and it works

Now I want to make my own event, this event will do something when the user authenticates using facebook. For example-will redirect the user to the home page.
I did it like this
http://symfony.com/doc/current/components/event_dispatcher/introduction.html

So I have this class

I do not know how to implement it, what am I supposed to pass as an argument to the constructor

Answer 1

Event object is just some kind of state/data storage. It keeps data that can be useful for dispatching some kind of events via Subscribers and/or Listeners. So, for example, if you wanna pass facebook id to your Listener(s) – Event is the right way of storing it. Also event is the return value of dispatcher. If you want to return some data from your Listener/Subscriber – you can also store it in Event object.
