Problems with Quiz Scoring Script

smithson123 · September 28, 2009

I am pretty much a novice and am having problems with the php script below. In the showScore function, question 4 is worth 2 marks with there being 2 correct answers out of a list of 4.

I've got as far as below and now i'm a bit stuck.

When i choose different answers for question 4 the scoring system does not work correctly. No doubt what I have done below is incorrect anyway but any help would be much appreciated

Thanks

<?php

$name = $_POST['userName'];

$email = $_POST['userEmail'];

$question1 = $_POST['Q1'];

$question2a = $_POST['Q2a'];

$question2b = $_POST['Q2b'];

$question2c = $_POST['Q2c'];

$question2d = $_POST['Q2d'];

$question3 = $_POST['Q3'];

?>

<title>Quiz Results</title>

<body>

<h1>Quiz Results</h1>

<?php

showFormInput();

?>

Question 4:

<?php

$question4 = $_POST['Q4'];

foreach ($question4 as $Q4) {

echo "$Q4 , ";

}

?>

<?php

showScore();

?>

To retake the quiz click <a href="quiz.html">here</a>

Submitted answers are stored in the <a href="quizResults.txt">quizResults</a> document

<?php

logResults("store");

?>

</body>

</html>

<?php

function showFormInput()

{

global $name, $email, $question1, $question2a, $question2b, $question2c, $question2d, $question3;

Print <<<END

Your Name: $name

Your Email: $email

Your answers were

Question 1: $question1

Question 2: $question2a $question2b $question2c $question2d

Question 3: $question3

END;

}

function showScore()

{

global $question1, $question2a, $question2b, $question2c, $question2d, $question3, $Q4, $score;

$score == 0;

if ($question1=="Apache")

$score=$score+1;

if ($question2a=="HTML")

$score=$score+1;

if ($question2b=="ECMA")

$score=$score+0;

if ($question2c=="WML")

$score=$score+0;

if ($question2d=="DOM")

$score=$score+1;

if ($question3=="Flexible")

$score=$score+1;

if ($Q4=="H1" ||$Q4=="DIV")

($score=$score+2);

echo "You scored $score out of 6";

}

function logResults($action)

{

global $name, $email, $question1, $question2a, $question2b, $question2c, $question2d, $question3, $Q4, $score;

$logEntry = <<< END

----------------

E-Mail: $email

Question 1: $question1

Question 2: $question2a $question2b $question2c $question2d

Question 3: $question3

Question 4: $Q4

Total Score: $score

END;

if ($action == "email") {

return $logEntry;

}

else {

$filename = "surveyLog.txt";

$fp = fopen($filename, "a+") or die ("Couldn't open $filename");

fwrite($fp,$logEntry);

fclose($fp);

}
