anyone can help me about this ?

hi..

i have 2 location stores and i add it as a category..(e.g product_category = location1, location2)

and each location has same product category but not the same product item

location1
category1
category2

location2
category1
category2

and on my checkout i want to include the location name on the product name

Item 1 (location1)

Hi,

An easy way could be to use the custom field with the type Item, create a new custom field in HikaShop > Display > Custom field in the table "Item" and the type "Text", assign it to the "location1" category including sub categories and set a default value, example "location1".
Do the same thing for the second location, and this field will be displayed on the product page and on the invoice, etc.

This kind of custom fields are in the business version of HikaShop.
