Storing the value from disabled radio button
I'm writing a short quiz where the user has a multiple choice question on each page. The idea is that they click one of three radio buttons and then the buttons are disabled and it shows a div with some feedback text on their correct or incorrect answer.
The problem is that I would like to store which answer they chose and pass it to the next page in a php session, but disabling the radio buttons after a selection obvious doesn't allow the value to be submitted then.
Is there some way I can keep the user from selecting another radio button after their first selection and still pass the value to the next page?
