PHP - quiz - why is my code not working?

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:



<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 ? -

<?
  $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

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:

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

 ...

</form>

example score script:

<?php

  $score = 0;

  if ($_POST['question1'] == 'a')

    ++$score;

  if ($_POST['question2'] == 'a')

    ++$score;

?>



YOUR SCORE IS: <? echo $score ?>

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

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.

thanks a lot matt. I got it to work though DR.p's sugestion worked. i should have posted that but thanks for offering ^_^

OK. If you need any more help just say...
