I'd like to find out a way to do the following:
When user clicks a link, a value is delivered with URL. A variable holds the value. The variable is registered with a session. This far it works fine.
But now I can register just one variable with the session. Every click replaces the previous value (I perfectly know why). I think I would have to change the name of variable to be registered every time the link is clicked. There's obviously no use for square brackets here.
I'm new to PHP so please be understanding.
