Need to remove shipping if a certain attribute is chosen

[lindsayanng]

So I have my store set up in a way that the attributes are actually the products and the product itself can't be purchased without an attribute. see here: My link

 

What is happening is, thgere is a weight associated with the product itself because we also have gift vouchers which need a weight of 0 to remove the shipping.. So is there a way to apply weights to the attributes? I have heavily modified attributes so i'm looking for some code exambles maybe so i can hopefully work it into the code myself.

Well without getting into the code (because I'm not at home right now), it should be a doable thing. What comes to mind is adding another field to products_attributes for the weight. Then either give it a default of NULL and program it to use product weight if null, or write a script to autopopulate the attribute's weight with the parent product's weight and then manually change weights of attributes after this.

 

You will have to change your queries and order total calculations. I remember you asked about a giftwrap/expedite shipping issue before... you would approach this the same way in terms of the order total calculation.

 

EDIT:

Or if you simply want to remove the product's weight if a specific attribute is selected, this would be easy. In your order total calculation, just do something like (very psuedo-code):

if (product_attribute == "whatever") { product_weight = 0; }

Sorry I'm not at home so I can't give you real code now...
