Hello,

I am writing a quiz for a Harry Potter role playing site i belong to. I figured that if i made a verriable called score and add 1 to it for each correct answer it would work, but for some reason it is not.

Here is my code:

(Toggle Plain Text)

<HTML>
   <Head>
       <Title>
           Interface
       </Title>
   </Head>

<Body>


<Div align="center">
   Welcome To the Transfigurations Midterm
      <BR>
   Proffesor: Damion Black
      <BR>
</Div>



<Div Align="center">
   <Form method="post">
      Name:
         <input name="Name" type="text">
            <br> 



         <li>
         What is blah
            <BR>
         <input name="question1" value="a" type="radio">
               Answer 1
            <BR>
         <input name="question1" value="b" type="radio">
               Answer 2
         </li>



         <li>
         what is mah
            <BR>
         <input name="question2" value="a" type="radio">
               Answer 1
            <BR>
         <input name="question2" value="b" type="radio">
               Answer 2
         </li>

            <BR>           
         <input type="submit" value="submit">
            <br />
   </form>


<?
  $score=0;
      
     if(question1 == "a")
       {
          $score=$score+1;
       }
     if(question2 == "b")
       {
          $score=$score+1;
       }

?>


</Div>

</Body>

</HTML>

- I have also tryed taking out the PHP and puting it in its own file and using the form action as that file.
- I have also tryd making the button action the php file.
-I have tryed making it $score=score++ , $score+1, and $score++

none of these have worked, I know this should be simple to pull off but i can not figure it out.

how about this ? -

 php Syntax (Toggle Plain Text) 
<?
  $score=0;
 
     if($_POST["question1"] == "a")
       {
          $score=$score+1;
       }
     if($_POST["question2"] == "b")
       {
          $score=$score+1;
       }
 
?>
<?
  $score=0;
      
     if($_POST["question1"] == "a")
       {
          $score=$score+1;
       }
     if($_POST["question2"] == "b")
       {
          $score=$score+1;
       }

?>

read some PHP tutorials FIRST ... ask questions later.

and i think : <input name="question1" value="a" type="radio"> should be
<input name="question1[]" value="a" type="radio"> but i;m not sure

no you can not use an array in HTML (the form itself is HTML the driver is PHP)

thanks for the help both of you i apreciate it greatly

You should probably have the score checking in a PHP script which your quiz form submits to. And in that score checking script, you should be checking $_GET['question1'] or $_POST['question1'], depending on your form submission method.

example form page:

(Toggle Plain Text)

<form action="grade.php" method="POST">
 ...
</form>

example score script:

(Toggle Plain Text)

<?php
  $score = 0;
  if ($_POST['question1'] == 'a')
    ++$score;
  if ($_POST['question2'] == 'a')
    ++$score;
?>

YOUR SCORE IS: <? echo $score ?>

Are you ever going back to the page and the score getting reset? is that what you are trying to handle? If you are then you need to create a hidden post value of their score and when you reload the page, you have to put it in.

I did a quiz like this on Latin nouns once. I'll go downstairs and try and find the DVD with it on and then you can have a look at that if you want.
