Reply to discussion (solution)

Function Page_Load ()
{
If ($ _ SESSION ["username"] = null)
Header ("Location: login. php ");
}
Is this useful? Where can I add useful words?

No ECSHOP used
But I think it should be:
Check whether the current user is a member in a public class or an entry file. if not, redirect the header to logon (exclude the homepage)

The language uses php, and asks different gods to save ing.
