これはphpMyAdminの上で動作しますが、私はコードを使用していたときに私とエラーになり、エラーが言う、解析エラー：>構文エラー、予期しない「％」....

いただきました！私のsintaxと間違っていますか？

<?php 

$database =& JFactory::getDBO(); 

//Declare Variables 
$user = JFactory::getUser(); 
$id = $user->get('id'); 
$name = $user->get('name'); 

// Display quizzes 
echo "</br>"; 
echo "Quizzes History for : " ; 
echo "<b>";

Answer 1

「マーク」をエスケープする必要があります。 ので、代わりに

DATE_FORMAT(quizSession.finished_on,'%M %d, %Y') 

の

DATE_FORMAT(quizSession.finished_on,\'%M %d, %Y\') 

してみてくださいそれとも、ただ起動し、文字列を終了するには、「二重引用符を使用することができます

Answer 2

あなたの文字列は単一引用符$database->setQuery('によって終了されるためです - 。ただ二重引用符に変更すると動作します。

$database->setQuery(" ");
