I have a Magento based site and Products are limited to Set of Pin codes. These PIN differ from product to product. What I need is to get an option to input set of PIN Codes, while defining a product. And on every product page there must be a Text field to check whether the product is available for the PIN Code, which is entered by the visitor.
HI For this first of all
1 create a new product attribute with multi-select type
2 assign all pin codes in there values under attribute options
3 assign that attribute to the desired attribute set
4 than for assigning attributes you need to go to product section and assign a desired zip options for that particular product from the multi-select attribute
5 on product page you need to problematically get all the selected values of that attribute
6 create a array of that values
7 create a simple form and when user post some value in that form , match that value in the array you defined above.
8 if the value finds in array than show the cart button and if not do what you want.
i hope this will give you a very fair idea. Let me know if i can do any other thing for you.
