We are looking to use HikaShop Starter to sell a software tool and would like to produce a serial (licence) key at time of order completion, basing the key on certain information provided by the purchaser. I understand that we can write a custom serial generator, but can we have HikaShop ask the purchaser to fill in a field, if the product requires it? Specifically, the key would be generated based upon the product id, a variant selection, and a piece of information entered by the purchaser (another "magic number" that we will give them). For products that don't require a licence, the user shouldn't need to (or be asked to) fill in the "magic number". Ideally, a licence key would then be emailed to them on payment confirmation. Is this possible with HikaShop Starter and HikaShop Serial?

HikaSerial would provide the features to generate the serials and attach them to the user and the order after completion (validation). If you want to retrieve some information provided by the customer during the purchase, you have to use some "custom fields" which are provided by commercial versions of HikaShop (the business edition for "order" and "items" custom fields). Order custom fields are information asked to the user during the checkout. The data is for the entire order. Item custom fields are information asked to the user when a product is added to the cart. The data is attach to the "order product". Best regards, --- Jerome - Obsidev.com HikaMarket & HikaSerial developer / HikaShop core dev team.

Not essential, but is it also possible to restrict the number of items purchased _per order line_ to one, yet still allow multiple purchases of the same item? i.e. something like... OrderLine:1 Item:MySoftware Qty:1 MagicNumber:1234 OrderLine:2 Item:MySoftware Qty:1 MagicNumber:5678 Or would HikaShop consolidate this to OrderLine:1 Item:MySoftware Qty:2 MagicNumber:5678 Thanks again, Oliver Please [Log in](/login?return=aHR0cHM6Ly93d3cuaGlrYXNob3AuY29tL2ZvcnVtLzE3LXNlcmlhbC1ob3ctdG8vODAwMzctY3VzdG9tLXNlcmlhbC1udW1iZXItYmFzZWQtb24taW5mb3JtYXRpb24taW4tb3JkZXI/dG1wbD1tYXJrZG93bg==) or [Create an account](/component/users/registration?Itemid=101) to join the conversation. - **[Jerome](/forum/user/80-jerome "View Jerome's Profile")** - [![Jerome's Avatar](https://www.hikashop.com/media/kunena/avatars/resized/size144/users/avatar80.png)](/forum/user/80-jerome "View Jerome's Profile") - [ Offline](/forum/user/80-jerome) - HikaShop core developer Less More - Posts: 26394 - Thank you received: 4078 - - [](http://obsi.dev) - 13 years 6 months ago - 13 years 6 months ago [\#97879](#97879) by [Jerome](/forum/user/80-jerome "View Jerome's Profile") Replied by *[Jerome](/forum/user/80-jerome "View Jerome's Profile")* on topic *[Custom serial number based on information in order](/forum/17-serial-how-to/80037-custom-serial-number-based-on-information-in-order#97879 "Hi There, Apologies in advance if this is a stupid question.

So, it would be like that: > OrderLine:1 Item:MySoftware Qty:1 MagicNumber:1234 > OrderLine:2 Item:MySoftware Qty:1 MagicNumber:5678 If the user change the quantity of a product (in this cart or when adding the product to the cart), you could have something like: > OrderLine:1 Item:MySoftware Qty:1 MagicNumber:1234 > OrderLine:2 Item:MySoftware Qty:2 MagicNumber:5678 Regards, --- Jerome - Obsidev.com HikaMarket & HikaSerial developer / HikaShop core dev team.
