Simple, really - dropdown lists that change their options depending on other
dropdown lists, but all done through Zend Dojo and using a nice clean MVC
interface. The classic example is Country / State - when you select the
Country from a dropdown, it refreshes the options available in the State
list to match the Country. This sort of functionality is pretty fundamental
stuff, and is really quite simple when you're just knocking it together in
regular ol' PHP/JS.
So far, I have a framework in place that builds these things really quite
cleanly, you can add a new pair of fields (or really as many as you want in
cascade, it should work fine) with 2 dojo divs and a tiny chunk of
Javascript, it just doesn't work when you're editing the row - the populate
method is passing the id value on to the view just fine, but I either need
to find a way to somehow trigger the options list to refresh on page load
(no idea if that will work, and I can't find any Dojo docs describing how to
do it), or, come up with a syntax that lets you pre-populate the dropdowns
while you're still assembling them in the Model. So far it seems that if you
addMultiOptions while there's a Store defined, the MultiOptions are ignored.
So I'm a bit stuck at the moment :/
I'd like to put a good tutorial together for this once it's done too,
because i'm sure a lot of other developers will need this in future, so it
will make fantastic SEO for my development company's blog :P
