Hello, I'm wondering if it's possible to setup Zencart to have sub attributes

basically what I need is

Category-->Product1-->Attribute1-->Attribute2

And I need these in a drop down list that populates the sub attribute;
for example to match the above layout

Mens-->Hoodies-->Colour-->Size


The reason I need it like this is because certain colours only have certain sizes available. Where as others might have all sizes available.

I have a client on Zen Cart and I don't think you can do what you exactly what you want. I wanted to do something similar awhile back and ended up using some PHP to check the one attribute before presenting the other. It was something like that. It was awhile ago when I first started working on the site so my memory is a little fuzzy.

You should be able to code it things so that the sub attribute drop down is populated based on the choice of the attribute drop down.

got any idea how? using ajax right? and do i need to install additional plugin before i make a code for it?

I don't think you'd need to install any additional plugins. Search for dynamic forms or dynamic drop downs or similar. Add Ajax to the search, but if that doesn't work just try javascript.

There's a lot of info and code out there for having one drop down change dynamically in response to another. Most every javascript book I've seen covers it too.

The basic idea would be when someone makes a selection in the first drop down (color) it would trigger a call to the database and populate the second drop down with the available sizes.

Last thing you know which exact template i need to change or add the sub attribute?

Thanks alot bud!!!

That's a good question. Now that I think about it the site I was working on was osCommerce. Everything above should still generally be the same, but I'll have to guess a little at the file(s) to change.

There's a product_listing.php under includes/modules that looks like a good candidate. If that's not it look for other product_ files in some of the other folders.

Zen Cart has a support forum on its site which will probably have info on the different files.
