Well, I am really not sure how to implement this on database-side either, so any feedback from you, more experienced people, would be very insightful.
Here is an example form of what I mean: A form that a user can enter books they like. So there is a title field that accepts the name of the book. Also there is a button 'Add more books' that will create an additional text field for the user to enter an additional book title. The amount of books a user can add is unconstrained, therefore, one user may add only 1 book and other user can add 100 books. I don't see how it is possible to store such information in a table in a conventional way. One way I am thinking to implement this, is to create a JSON string that contains all the information of the form and just enter that into the table. What do you think about this method? Thanks again.
