Re: referencing objects within objects

I think there is one thing you need to change. In the function fieldClass, just change it to "$this->fetchresult = ...". Now you have a class variable and you can then do $field = new fieldClass; echo $field->fetchresult->blob; -- Jesse Swensen swensenj@bellsouth.net > From: "TSHACK" <TSHACK@SILVER-BAYOU.COM> > Date: Fri, 17 Nov 2000 05:44:46 -0800 > To: <php-general@lists.php.net> > Subject: [PHP] referencing objects within objects > > I have an object called formCass.
