I sell cooking classes online. So people can buy their participation online, by chosing the date (1 date=1 characteristic of the product). Their can be multiple dates for one product (1 product = 1 cooking class type)

but, how can i can display all the orders made for a specific characteristic ? in my case, i want to know, how many orders there have been on a given date(characteristic) of the product

i wrote a php programme to do this for me, but isn't this part of hikashop ?
