Hi. I'm building a website which has an upload file component.
Now for some UX reasons, I let users upload their documents before making an account in the first step and save their file metadata into a table. I have to do some calculations on the documents and show them a price and then in the second step let them make an account.
Know the question is how to remember which file belongs to which user in the third step? Can I use local storage or it's risky? How should I handle the steps and make a relationship between a user and an uploaded document?
What's the best practice?
I would go with a cookie. User visits your site -> set cookie with an unique id. User uploads documents -> use that id and prefix the filenames. User registers -> Parse the files and assign the user to it.
Note: Any client side method may break if the user uses private sessions or things like NoScript
Why not just ask them for their email when they upload the image?
@RONON - Tanx, I like this approach. I'll try it out but maybe it's better to save the unique cookie inside the database instead of adding to filenames.
@TRAY2 - It's for UX issues.
