Some Items can't ship by postal/air

I sell a mix of products. One of the more popular products is flammable liquid and cannot be shipped through the postal service, nor by any of the air options of Fedex/UPS.

How can I limit the shipping options display to just show UPS and FEDEX ground services for this product while still having the ability to show other services for other products?

I will be upgrading to ZenCart v1.3.5 very shortly.

You would need to customize the shipping modules by either using an existing flag such as a products_model or products_id etc. and having that option not show if the Product is in the cart ...

Or, adding a new flag such as products_is_flamable and use that as a method to determin what is in the cart and then turn on/off the shipping module or a given pricing option ...

Thanks for the guidance Linda.

It might be a bit of a stretch for me to write my own code modifications. I'll take a look at the code for the flags you mentioned and I might be able to clone one of them for a products_is_flammable flag. This will be a bit risky since I probably won't understand how the code works.

I'll post how it was done, if I can make a workable mod.
