Hi Joel,
from what you wrote it seems that only the type of display is similar in
both classes. I don't think this is enough to extend them from the same base
class because the class properties and update/insert/load methods will be
different in each.
You have more of a 'is part of' relationship here. So I'd suggest something
like this (simplified):
class Portfolio {
var $portfolioID;
var $albums = array();
}
class Album {
var $albumID;
var $portfolioID;
var $photos = array();
}
class Photo {
var $photoID;
var $albumID;
var $name;
}
Just my 2c.
Regards, Torsten Roehr
