I have a form with x questions (the questions come from a database, so the number of questions is variable). Each question needs to be answered with a number form 1 to 10, I do this using radio buttons. The name if those radio buttons is "name" followed by the id of the question in the database.

Because the name is variable and the number of questions is variable, how can I check if all the questions are answered i.e. one radio button must be checked for every group of radio buttons.

I tried a lot and read the documentation, but I just can't find how to achieve this. Could you help me out? Thanks in advance.
