Quiz

Hi Stephen

I followed the same thread as you linked to in your posting. And I altered the code to make it work with moodle 1.6. Here is the code:

attempt.php

$catraw = $catmax = $catperc = array(); // blank arrays to store category information
foreach($questionidarray as $i) {
   if (!isset($actions[$i])) {
     $actions[$i]->responses = array('' => '');
     }
   $actions[$i]->timestamp = $timestamp;
   question_process_responses($questions[$i], $states[$i], $actions[$i], $quiz, $attempt);
   if (!isset ($catraw[$questions[$i]->category])) { // if this category has not been seen before
     $catraw[$questions[$i]->category] = 0; // set the raw total to 0
     $catmax[$questions[$i]->category] = 0; // set the maximum possible points to 0
     }
   $catraw[$questions[$i]->category] += $states[$i]->raw_grade; // add to the raw grade achieved for this category
   $catmax[$questions[$i]->category] += $questions[$i]->maxgrade; // add to the max grade possible
   save_question_session($questions[$i], $states[$i]);
 }

 foreach ($catraw as $categoryid=>$categorygrade) { // for each category involved in this quiz
   if (($category = get_record('question_categories', 'id', $categoryid)) && ($catmax[$categoryid]>0)) { // look up the category name
     array_push ($catperc, $category->name.': '.round ($categorygrade/$catmax[$categoryid]*100).'%');
      }
   }
   sort ($catperc); // sort the categories by key
   $attempt->categorygrades = join ("\n", $catperc); // put this information in the new categorygrades field

review.php

$table->data[] = array("$strgrade:", get_string('outof', 'quiz', $a));
$table->data[] = array("Categories:", nl2br($attempt->categorygrades));

I get the results for each categori.
