vBQuiz 1.0

NOTE: all functionality-impairing bugs have been fixed. The attached files should work well on just about any PHP installation.

What's it do?
It allows you to setup a quiz center on your boards quickly and easily. This quiz center is FULLY templated, integrated with vBulletin, and has an advanced Admin script for managing the quizzes, categories, and questions. Here's an example: Movie Forums - Quizzes

A few of its features...

• Tracks all results and displays high scores.
• Upon completion, users are given a total quiz breakdown of the quiz, showing them how they fared on each question, and, on the ones they missed, showing them the correct answer.
• Upon completion, users are shown a graphical bar representing their score, and a graphical bar representing the average score for the quiz. They are also emailed their information.
• Main quiz page calculates and displays the easiest and most difficult quizzes automatically.
• Quizzes can be split up into categories.
• Quizzes can be approved or disapproved easily to add/remove them from public view/use.
• Full integration with the Who's Online? page...IE: "Viewing Quizzes" or "Viewing So and So Quiz" and even "Taking So and So Quiz"

Admin Abilities:

• Disallow multiple quiz takings.
• Toggle to disinclude quiz results coming from the author of the quiz.
• Change the display order of the answers to each question.
• Add multiple questions and answers at once (no limit).

Here are some screenshots:

• Main Quiz Page
• Quiz Display
• Quiz Category Display
• Quiz Question Display
• Quiz Results Page
• ADMIN: Quiz Options/Navigation
• ADMIN: Add Quiz
• ADMIN: Add Questions
• ADMIN: Delete Quiz
• ADMIN: Modify Question
• ADMIN: Quiz Settings

That's it! Don't forget, however, to read ALL of the instructions.txt file in the enclosed vbquiz.zip file. It'll help guard against some common bugs.

Files Enclosed (in vbquiz.zip)
- instructions.txt (read it!)
- quiz.php (upload to main forum dir)
- admin_quiz.php (upload to admin dir)
- install_quiz.php (upload to admin dir and then run)

Enjoy!

Also: a HUGE, HUGE, HUGE thanks to GamerForums for beta testing this hack for me. His help was completely invaluable and surely saved me a lot of work in the long run. Thanks!

just installed it on 2.2.9, great hack.

i was wondering if there was any way to have "Quizzes" displayed as a category on the forum index, with the quiz categories as forums, and then the quizzes in the individual category forums, displayed as posts or something similar?

thanks.

I noticed that when user put the answer text less than the one indicated when they make their quiz, it will appear as blank.

For example: user input 3 answers per question.
but when they input answer texts for a question, they put only 2 answers,

so when they display the quiz, it will appear two answers with one blank answer.

this solution will display only two answers.

one way to prevent this is prevent from display those blank answer

here is the solution
look for this code

PHP Code:

eval("\$answerbits .= \"".gettemplate("quiz_answerbit")."\";"); 


replace with this code

PHP Code:


   if ($answer[answertext] !="") {
          eval("\$answerbits .= \"".gettemplate("quiz_answerbit")."\";");
}

Thanks man. You rock! This will make finding a particular quiz to take 10x easier.

After over 3 weeks of testing, I have one complaint.
Users are registering now simply to take the quizzes and not posting on the forums. I wouldn't mind this, but even users that haven't verified their e-mail address are able to take the quizzes. Is there any way to stop them from being able to do this?

in quiz.php, near the top u will find this line

PHP Code:

if ($bbuserinfo[userid]==0) {
  show_nopermission();
} 


change 0 to number of usergroup that u want them to have access
if more than 2 usergroups then use "or" between them.

Okay no idea why, but figure l will add this one and work out the exact reason in due course

Fine looking hack btw....

Could people stop posting links to show off their site's using the quiz hack, when you need to register to view those links.

I didn't want to wade through 46 pages, but I had to make an adjustment in order for the percentages to work right. The % correct at the bottom was showing the right amount, but the % correct at the top was not (on the results page) It was showing 6 out of 6 - 102%

Anyway, here's the change I made, if it hasn't already been documented:

Find:

PHP Code:

    $avg  = round($all / $number, 2);
    $base = round(100 / $question_count);

    $multiplied_total   = $total * $base;
    $multiplied_average = round($avg * $base);

    $total_bar_multiply     = $multiplied_total * $resultsbarmultiply;
    $avg_total_bar_multiply = round($multiplied_average * $resultsbarmultiply); 


Change to:

PHP Code:

    $avg  = $all / $number;
    $base = 100 / $question_count;

    $multiplied_total   = ceil($total * $base);
    $multiplied_average = ceil($avg * $base);

    $total_bar_multiply     = $multiplied_total * $resultsbarmultiply;
    $avg_total_bar_multiply = ceil($multiplied_average * $resultsbarmultiply);
