Order : Quantity amount

[daseb]

Hello !

 

Sorry for my english, i'm french ...

 

I've got un problem with the quantity when adding a product to shoppingcart.

 

The minimum of product to order can be set in the admin , ok.

 

But i want something like that :

 

For exemple if the minimum quantity is set to 2.

Then if i want to order more than 2, i m must write in quantity field : 4, or 6, or 8, or 10 etc...

 

Another exemple : if set is 3, in the field i can write only 6, 9, 12, .... (if i write 7 i ve got an error message)

 

It must be a multiple of the number set in the admin.

 

 

I'm not developer, so i need help :-(

 

Thank you very very very much !!

Make a pack-product like a product named "2 bananas" or "3 bananas", so if they buy one they get 2 or 3.

There is a checkbox inside the product named "Pack" if you check it then you can add two "1 banana" to the pack.
