data not inerted correctly when going through a loop - php

Question

$answersql = "INSERT INTO Penalty_Marks (PenaltyAnswer, PenaltyMarks, QuestionId)
VALUES (?, ?, ?)";
if (!$insertanswer = $mysqli->prepare($answersql)) {
// Handle errors with prepare operation here
}
$c = count($_POST['incorrect']);
for($i = 0; $i < $c; $i++ )
{
$incorrect = $_POST['incorrect'][$i];
$answerMarks = $_POST['answerMarks'][$i];
$numQuestion = $_POST['numQuestion'][$i];
$insertanswer->bind_param('sii', $incorrect, $answerMarks, $numQuestion);
$insertanswer->execute();
}
The above insert is not inserting all the incorrect answers into the table, it is only inserting one incorrect answer per question. What am I doing wrong?
Below is the currect db table looks like:
PenaltyAnswerId PenaltyAnswer PenaltyMarks QuestionId
1 A 4 12
2 D 1 13
Below is what it should of been like:
PenaltyAnswerId PenaltyAnswer PenaltyMarks QuestionId
1 A 4 12
2 B 3 12
3 D 0 12
4 D 1 13
5 E 1 13
Below is form:
<form id="PenaltyMarks" action="insertpenaltymarks.php" method="post">
<table id='penaltytbl'>
<?php
foreach($ques_ans as $questionId => $inc_ans)
{
$q_row_span = count($inc_ans);
$row_count = 0;
$inc_ans = array_values($inc_ans);
?>
<tr class="questiontd">
<td>
<input type="hidden" name="numQuestion[]" value="<?php echo$questionId?>" />
</td>
<td>
<input type="hidden" class="hiddenincorrect" name="incorrect[]" value="<?php echo$inc_ans[$row_count];?>">
</td>
<td>
<input name="answerMarks[]" type="text" data-type="qmark" value='0' />
</td>
</tr>
<?php
//remaining incorrect answers in separate row (if any) follows here
if($row_count < $q_row_span - 1)
{
for($i=($row_count + 1); $i<$q_row_span; $i++) { ?>
<tr>
<td>
<input type="hidden" class="hiddenincorrect" name="incorrect[]" value="<?php echo$inc_ans[$i];?>">
</td>
<td class="answermarkstd">
<input name="answerMarks[]" type="text" data-type="qmark" value='0' />
</td>
</tr>
<?php
}
}
}
?>
</table>
<input id="submitBtn" name="submitPenalty" type="submit" value="Submit Marks" />
</form>
Below is jquery handling submit:
myClickHandler = function(e) {
if (confirm("Are you sure you want to Proceed?" + "\n")) {
$.ajax({
url: "insertpenaltymarks.php",
data: $("#PenaltyMarks").serialize(),
async: false,
type: "POST"
});
return true;
} else {
return false;
}
};
$('#PenaltyMarks').submit(myClickHandler);
});
UPDATE:
Question Table:
QuestionId (PK auto) (int 10)
QuestionNo (int 4)
QuestionContent (varchar 5000)
Penalty_Marks Table;
PenaltyAnswerId (PK auto) (int 10)
PenaltyAnswer (Varchar 5)
PenaltyMarks (int 3)
QuestionId (FK) (int 10) Reference to QuestionId in Question Table

Updated
With your current code, you can var_dump and found that the $_POST['numQuestion'] array may contains a fewer member than the $_POST['incorrect'][$i] array. I have updated my code too.
<form id="PenaltyMarks" action="insertpenaltymarks.php" method="post">
<table id='penaltytbl'>
<?php
foreach($ques_ans as $questionId => $inc_ans)
{
$q_row_span = count($inc_ans);
$row_count = 0;
$inc_ans = array_values($inc_ans);
?>
<tr class="questiontd">
<td>
<input type="hidden" name="numQuestion[<?php echo $questionId; ?>]" value="<?php echo$questionId?>" />
</td>
<td>
<input type="hidden" class="hiddenincorrect" name="incorrect[<?php echo $questionId; ?>][]" value="<?php echo$inc_ans[$row_count];?>">
</td>
<td>
<input name="answerMarks[<?php echo $questionId; ?>][]" type="text" data-type="qmark" value='0' />
</td>
</tr>
<?php
//remaining incorrect answers in separate row (if any) follows here
if($row_count < $q_row_span - 1)
{
for($i=($row_count + 1); $i<$q_row_span; $i++) { ?>
<tr>
<td>
<input type="hidden" class="hiddenincorrect" name="incorrect[<?php echo $questionId; ?>][]" value="<?php echo $inc_ans[$i];?>">
</td>
<td class="answermarkstd">
<input name="answerMarks[<?php echo $questionId; ?>][]" type="text" data-type="qmark" value='0' />
</td>
</tr>
<?php
}
}
}
?>
</table>
<input id="submitBtn" name="submitPenalty" type="submit" value="Submit Marks" />
</form>
The insertion script should be changed too :)
foreach($_POST['incorrect'] as $questionId => $incorrectArray)
{
for($i = 0; $i < count($incorrectArray), $i++)
{
$incorrect = $_POST['incorrect'][$questionId][$i];
$answerMarks = $_POST['answerMarks'][$questionId][$i];
$numQuestion = $_POST['numQuestion'][$questionId];
$insertanswer->bind_param('sii', $incorrect, $answerMarks, $numQuestion);
$insertanswer->execute();
}
}
