Hello,
How can i simply generate serials by shipment method ? So that the customer can choose betweeen postal tickets and e-tickets by e-mail? Variants dont give use the right feeling in frontend.
Serials are generated by the assignation of a pack with a product ; when that product is sold, a serial is generated.
"Attach Serial" and "PDF Serials" generate attachments (in emails or available via product downloads) depending the pack.
There is no link or relation with "shipment method".
For relation between product and shipment ; it's an HikaShop question ; and the answer is the "weight" of the product to make a difference between a "virtual product" and a "physical product". One can be shipped, the other no.
So the way to make the difference in HikaSerial is to have two different products ; one for the "download" and the other for the "print".
Variants is a solution to have two different "products" within one products displayed in your shop.
Now, if you want to customize the behavior, it's still possible to create "custom plugins" using PHP and the HikaShop+HikaSerial triggers.
With custom code you can add your own logic and own rules ; you can change when a download can be available for a products, etc.
Regards,
