Re: Morph an object

Torben, Thanks for your help. I got it to work by creating a constructor that took the content as an argument then set the property $this->content = SetContent($content); Then in my script I instantiated the object with the login form as the content. I created a switch case for the result of the login routine and within each case I re-invoked the constructor with a different argument to change the content. Then when I called the Display() function again, it changed the screen on the browser... I really appreciate all your help! /T on 6/5/03 4:12, Lars Torben Wilson at torben@php.net wrote: > On Wed, 2003-06-04 at 17:18, Info@Best-IT wrote: >> You have the problem right.
