I am certain isset() is working exactly the way it is supposed to. Check that you are using the correct function for what you need to do, it might not be isset() that you want to be use.
isset( $var ) is a PHP function which returns TRUE or FALSE depending on whether a specified $var has been assigned to any value (or, initialized).
Its an easy PHP code
Radio Buttons allow only one value between them. For eg. Male or Female. So there is no point in declaring a loop for it. You could store the value like any other form elements. If you declare different names for radio buttons then & then only use this:OrangeAppleGrapesFile: action.phpIdeally a checkbox is better suited to have multiple values
