Session checking & loading a new view depending on the result

Hello All,

I am new to CI and now working with Session Management. I have to check the save the data in the Session and load a new view after successful login. Yesterday I completed the login checking & session storing tasks.

After login, the left menu which shows the 'Login Box' need to be replaced with a Welcome Message and a logout link. So how can I accomplish this?

How can I call a same function which displays this Welcome Message from within all classes ?

I am waiting here to hear from you all..

Thank You,
Php Developer.
