以下のコードで、データベースから取得した質問を表示しています。
$qandaquery = "SELECT q.QuestionId, q.QuestionNo, q.QuestionContent
FROM Question q
WHERE SessionId = ?
GROUP BY q.QuestionId
ORDER BY q.QuestionId";
$qandaqrystmt=$mysqli->prepare($qandaquery);
// You only need to call bind_param once
$qandaqrystmt->bind_param("i",$session);
// get result and assign variables (prefix with db)
$qandaqrystmt->execute();
$qandaqrystmt->bind_result($qandaQuestionId,$qandaQuestionNo,$qandaQuestionContent);
$arrQuestionId = array();
$arrQuestionNo = array();
$arrQuestionContent = array();
while ($qandaqrystmt->fetch()) {
$arrQuestionId[ $qandaQuestionId ] = $qandaQuestionId;
$arrQuestionNo[ $qandaQuestionId ] = $qandaQuestionNo;
$arrQuestionContent[ $qandaQuestionId ] = $qandaQuestionContent;
}
$qandaqrystmt->close();
foreach ($arrQuestionId as $key=>$question) {
?>
<div class='lt-container'>
<p><strong>QUESTION <span id="quesnum"></span>:</strong></p>
<p><?php echo htmlspecialchars($arrQuestionNo[$key]) . ": " . htmlspecialchars($arrQuestionContent[$key]); ?></p>
</div>
<?php
}
?>
今それが言うところQUESTION
:
<p><strong>QUESTION # <?php echo $q; ?> :</strong></p>
<?php
$q++;
?>
同じ場所にとどまりたい
ただし、質問の詳細が表示される場所:
<p><?php echo htmlspecialchars($arrQuestionNo[$key]) . ": " . htmlspecialchars($arrQuestionContent[$key]); ?></p>
質問をランダムな順序で表示したい。たとえば、次の3つの質問がある場合:
QUESTION 1:
1. What is 2+2?
QUESTION 2:
2. What is 3+3?
QUESTION 3:
3. What is 4+4?
例として、次の順序で表示できます。
QUESTION 1:
2. What is 3+3?
QUESTION 2:
3. What is 4+4?
QUESTION 3:
1. What is 2+2?
