Change filename for image field on upload or download

I take this comment from 2017.
And now in 2020 I need this now exactly!!


Hi Knack, it would be cool if an image and file field would have the possibility to auto-name the file, once downloaded.

So lets say, that I have a form where job applicants can sign up.
There would be a Name field and for the applicant, and they would also have to upload an image of themselves.

When I then view the applicants and want to download their image,
I would be nice If I could say that the image should be generated with a file name
that consists of data from one or more other
fields - fx. their Name, Age and applicant number,

so that the image would be named Lisa-Jensen-38-17.

Hope someone can help me.
Thanks!!

Brad, yes JotForm is an incredible service everything works great PDF converter and their card style forms I've been using for years. https://www.jotform.com/form-templates/?cards

Good find on Jotform Tony. Have you used the PDF editor by any chance mate?

To accomplish things like this i have resorted to Jotform.com with Integromat.com combined with S3 the same file storage service that knack uses. With this combination of services, I am able to use any file name or structure I prefer, and a nice form upload service from Jotform combined with API logic from Integromat. And of course Knack for the database and UX They work great together
