moodle如何在數據庫中保存用戶測驗回覆？

Question

moodle1.9如何將用戶嘗試測驗結果保存在數據庫中，並在用戶嘗試進行測驗時更新哪些表？

請指導我。

如果可能請更新我，哪些函數用於在moodle1.9數據庫中插入用戶測驗數據？

Answer 1

從attempt.php文件（Moodle的1.9.7）：

$attempt = quiz_create_attempt($quiz, $attemptnumber); 

然後：

if (!$attempt->id = insert_record('quiz_attempts', $attempt)) { 
      error('Could not create new attempt'); 
     } 

從locallib.php：

/** 
* Creates an object to represent a new attempt at a quiz 
* 
* Creates an attempt object to represent an attempt at the quiz by the current 
* user starting at the current time. The ->id field is not set. The object is 
* NOT written to the database. 
* @return object    The newly created attempt object. 
* @param object $quiz   The quiz to create an attempt for. 
* @param integer $attemptnumber The sequence number for the attempt. 
*/ 
function quiz_create_attempt($quiz, $attemptnumber) { 
    global $USER, $CFG; 

    if (!$attemptnumber > 1 or !$quiz->attemptonlast or !$attempt = get_record('quiz_attempts', 'quiz', $quiz->id, 'userid', $USER->id, 'attempt', $attemptnumber-1)) { 
     // we are not building on last attempt so create a new attempt 
     $attempt->quiz = $quiz->id; 
     $attempt->userid = $USER->id; 
     $attempt->preview = 0; 
     if ($quiz->shufflequestions) { 
      $attempt->layout = quiz_repaginate($quiz->questions, $quiz->questionsperpage, true); 
     } else { 
      $attempt->layout = $quiz->questions; 
     } 
    } 

    $timenow = time(); 
    $attempt->attempt = $attemptnumber; 
    $attempt->sumgrades = 0.0; 
    $attempt->timestart = $timenow; 
    $attempt->timefinish = 0; 
    $attempt->timemodified = $timenow; 
    $attempt->uniqueid = question_new_attempt_uniqueid(); 

    return $attempt; 
}
