How can I see if the user's choice in the quiz is correct?

Question

I am trying to check if the answer that the user chose was correct, but it doesn\'t work properly:

Answer 1

Here's another attempt at helping you.

I actually wrote a "complete solution", and in the process discovered a few little bugs in your code - plus some things I just couldn't understand.

Principal bug: all your radio buttons have the same value ($x), so no matter what button you press for question 1, the answer is "1", etc. There were other things you did that I could not quite figure out - so what I did instead was create a simple flow - one page that asks the questions, and another that evaluates the results.

Question page (I obfuscated access parameters for my database - no, I don't use "password" as my password!):

';
   echo '' .$row['answer1'] . '
';
   echo '' .$row['answer2'] . '
';
   echo '' .$row['answer3'] . '
';
   echo '' .$row['answer4'] . '
';
   $x = $x + 1;

}
mysql_close($server);
?>

and evaluate.php: EDIT: I changed the code a bit to make the output "cleaner", and add a red/green touch to show questions that had been answered correctly and incorrectly. Obviously you can take these things much further if you want...

';

    $answered = $row['answer'.$_POST['a'.$x]] ;
    $correct = $row['correct'] ;

    if ($answered == $correct ) {
        $score++;
        $acolor = 'green' ;
    }
    else {
        $acolor = 'red' ;
    }

    echo 'you answered ' . $answered . ' 
';


    echo 'the correct answer was ' . $correct . '
' ;
    echo '-------------------------------------- 
' ;

    $x = $x + 1;
}
echo 'You had a total of ' . $score . ' out of ' . $x . ' questions right!';
mysql_close($server);
?>

This produced (for a simple three-question multiple choice I made) the expected results. Let me know if it works for you!
