Quiz Question module. This module provides the basic facilities for adding quiz question types to a quiz.

Code

function quiz_question_evaluate_question($question, $result_id, $answer = NULL) {
  if (empty($answer) && !empty($_POST['tries'])) {

    // FIXME this use of POST array is hacky. We will try to use FAPI mor accurately in Quiz 5.x
    $answer = $_POST['tries'];
  }
  unset($_POST['tries']);
  $response = _quiz_question_response_get_instance($result_id, $question, $answer);

  // If a result_id is set, we are taking a quiz.
  if ($result_id && isset($answer)) {

    // We don't know whether or not the user has gone back a question. However,
    // we do know that deleting a question for this result set should be safe in
    // the case where the user has not gone back (since there will be no entries
    // to delete). So we always run the delete.
    $response
      ->delete();
    $response
      ->saveResult();
  }

  // Convert the response to a bare object.
  return $response
    ->toBareObject();
}
