Upload customer files with multiple selection (qty not fixed)

[Wartin]

Hello.

I see that, after setting a fixed number of file upload in a product backoffice's page, a customer can upload image files to an item just before adding it to the order. I would like to let it upload as many pictures as the quantity selected for the item.

For instance, he would select the quantity, and then scroll down the order, using a 'multiple' input to let him select his pictures (using ctrl or shift to allow multiple selection).

I read the code for several hours, I think I understand more or less the way it manages to upload the files, taking the IDs, making the image processing, adding to the DB, but I think I'am not able to make the appropriate changes without screwing things up.

 

I'd like to know if is it possible to select multiple files at once.

It is intended for the costumers to print files in a simple way, after buying copy size they want.

The other related question would be how to let the customers upload a different type of file, maybe they can upload all their images in a .zip file.

Thank you very much.
