Class

MatchingResponse

Class that describes a "Directions question response". For the most part, no real scoring takes place for a direction node. However, there are a few behind-the-scenes tricks that are done here to make the quiz-taking process a little easier.

Code

public function score() {
  $wrong_answer = 0;
  $user_answers = isset($this->answer) ? $this->answer : $this
    ->getUserAnswers();
  $user_answers = isset($user_answers) ? $user_answers : array();

  // to prevent warning : Invalid argument supplied for foreach()
  foreach ($user_answers as $key => $value) {
    if ($key != $value) {
      $wrong_answer++;
    }
  }
  $this->score = !empty($user_answers) && !$wrong_answer ? 1 : 0;
  return $this->score;
}
