I have a question on how to display the correct table layout in my php code:
I want to display answers and their text inputs in a table.. Now at the moment it is displayed as below:
QuestionNo Question Answer Marks Per Answer
1 What is 2+2 B (text input)
2 Name the 3 hobbits? BCE (text input)
I want to change the display of the table so that it looks like this below:
QuestionNo Question Answer Marks Per Answer
1 What is 2+2? B (text input)
2 Name the 3 Hobbits? B (text input)
C (text input)
E (text input)
- As you can see from the new display. I want the each answer per question to be displayed in thier own row, not all answers per question in in one row which is what it is doing at moment.
- I want the text inputs to also be display in its own row, like the answers:
My question is that how can point 1 and 2 be achieved so that it can match the new layout?
Below is the code for the current display:
<?php
$assessment = $_SESSION['id'] . $sessionConcat;
include('connect.php');
$query = "SELECT q.SessionId, s.SessionName, q.QuestionId, q.QuestionContent,
GROUP_CONCAT(DISTINCT Answer ORDER BY Answer SEPARATOR '') AS Answer,
q.QuestionMarks
FROM Session s
INNER JOIN Question q ON s.SessionId = q.SessionId
JOIN Answer an ON q.QuestionId = an.QuestionId AND an.SessionId = q.SessionId
WHERE s.SessionName = ?
GROUP BY an.SessionId, an.QuestionId
ORDER BY q.QuestionId, an.Answer
";
// prepare query
$stmt=$mysqli->prepare($query);
// You only need to call bind_param once
$stmt->bind_param("s", $assessment);
// execute query
$stmt->execute();
// This will hold the search results
$searchQuestionId = array();
$searchQuestionContent = array();
$searchAnswer = array();
// Fetch the results into an array
// get result and assign variables (prefix with db)
$stmt->bind_result($dbQuestionId, $dbQuestionContent, $dbAnswer);
while ($stmt->fetch()) {
$searchQuestionId[] = $dbQuestionId;
$searchQuestionContent[] = $dbQuestionContent;
$searchAnswer[] = $dbAnswer;
}
?>
</head>
<body>
<form id="QandA" action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post">
<?php
echo "<table border='1' id='markstbl'>
<tr>
<th class='questionth'>Question No.</th>
<th class='questionth'>Question</th>
<th class='answerth'>Answer</th>
<th class='answermarksth'>Marks per Answer</th>
<th class='noofmarksth'>Total Marks</th>
</tr>\n";
$previous_question_id = null;
foreach ($searchQuestionContent as $key=>$question) {
if ($previous_question_id == $searchQuestionId[$key]) {
$searchQuestionId[$key] = '';
$question = '';
}else{
$previous_question_id = $searchQuestionId[$key];
}
echo '<tr class="questiontd">'.PHP_EOL;
echo '<td class="optiontypetd">'.htmlspecialchars($searchQuestionId[$key]).'</td>' . PHP_EOL;
echo '<td>'.htmlspecialchars($question).'</td>' . PHP_EOL;
echo '<td class="answertd">';
echo $searchAnswer[$key];
echo '</td>' ;
echo '<td class="answermarkstd"><input class="individualMarks" name="answerMarks[]" id="individualtext" type="text" "/></td>' . PHP_EOL;
echo '<td class="noofmarkstd">'.htmlspecialchars($searchMarks[$key]).'</td>' . PHP_EOL;
}
echo "</table>" . PHP_EOL;
?>
</form>
</body>
Below is what the Session, Question and Answer Table looks like:
Session Table:
SessionId (auto) SessionName
1 AAA
2 AAB
Question Table:
SessionId QuestionId (auto) QuestionContent
1 1 What is 2+2?
1 2 Name the 3 hobbits?
Answer Table:
AnswerId (auto) SessionId QuestionId Answer
1 1 1 B
2 1 2 B
3 1 2 C
4 1 2 E
Change
GROUP_CONCAT(DISTINCT Answer ORDER BY Answer SEPARATOR '') AS AnswertoAnswerand try making this change in theforeachloop.
