Question

我编写了以下代码，但不知何故标题与渲染表中生成的列不匹配，有人可以给我一些如何改进它的提示吗？

    <?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>";
echo $name;
echo "</b>";


echo "</br>";
echo "</br>";

$database->setQuery('SELECT distinct qui.title AS name,' .
        ' ( SELECT GROUP_CONCAT(profiles.title) 
              FROM #__jquarks_users_profiles AS users_profiles
              LEFT JOIN #__jquarks_profiles AS profiles ON users_profiles.profile_id = profiles.id
              WHERE users_profiles.user_id = sessionWho.user_id ) AS profile, ' .
        ' ( SELECT sum(score)  
              FROM #__jquarks_quizzes_answersessions
              WHERE quizsession_id = quizSession.id
              AND status <> -1 ) AS score,' .
        ' ( SELECT count(distinct(question_id))
              FROM #__jquarks_quizzes_answersessions 
              WHERE quizsession_id = quizSession.id ) AS maxScore,' .

            ' ( SELECT count(id)
              FROM #__jquarks_quizzes_answersessions 
              WHERE status=-1
              AND quizsession_id = quizSession.id ) AS evaluate,' .
' quizSession.finished_on,sessionWho.email' .     
        ' FROM #__jquarks_quizsession AS quizSession' .
        ' LEFT JOIN #__jquarks_users_quizzes AS users_quizzes ON users_quizzes.id = quizSession.affected_id' .
        ' LEFT JOIN #__jquarks_quizzes AS qui ON users_quizzes.quiz_id = qui.id' .
        ' LEFT JOIN #__jquarks_quizzes_answersessions AS quizSessAns ON quizSessAns.quizsession_id = quizSession.id' .
        ' LEFT JOIN #__jquarks_sessionwho AS sessionWho ON sessionWho.session_id = quizSession.id' .
        ' LEFT JOIN #__jquarks_users_profiles AS users_profiles ON users_profiles.user_id = sessionWho.user_id' .
' LEFT JOIN #__jquarks_profiles AS profiles ON profiles.id = users_profiles.profile_id '.

' WHERE sessionWho.user_id =' .$id) ;

if (!$database->query()) { //write data and if error occurs alert
    echo "<script> alert('".$database->getErrorMsg()."'); </script>";
}

//var_dump($database);
$tableStyle = "padding: 5px;border:1px"; 
$tdStyle = "padding:5px "; 

echo '<table style="' . $tableStyle . '" cellpadding="7" cellspacing="7">'; 
echo "<tr> <th> Quiz Title </th><th> Score </th><th>Maximum Score </th><th> Unanswered </th> <th>Finished On </th></tr>"; 

$row = $database->loadRowList();
foreach($row as $valuearray)
{
echo '<tr style=" align="center">';
foreach($valuearray as $field)
{

echo "<td>$field</td>";
}
echo "</tr>";
}
echo "</table>";
?>

您有5个<th>标题，但从表中选择了6列。要么显式打印所需表格中的字段（应该），要么将查询更改为仅选择所需的5个字段。
