通過循環時數據未被正確調整

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(); 

} 

上述插入操作並未將所有不正確的答案都插入到表中，而是每個問題只插入一個不正確的答案。我究竟做錯了什麼？

下面是當期的db表的樣子：

PenaltyAnswerId PenaltyAnswer PenaltyMarks QuestionId 
1    A    4    12 
2    D    1    13 

下面是它應該的一直喜歡：

PenaltyAnswerId PenaltyAnswer PenaltyMarks QuestionId 
1    A    4    12 
2    B    3    12 
3    D    0    12 
4    D    1    13 
5    E    1    13 

下面表格：

<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> 

下面是jQuery的處理提交：

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

更新

以您目前的代碼，你可以var_dump，發現$_POST['numQuestion']陣列可能含有比$_POST['incorrect'][$i]陣列較少成員。我也更新了我的代碼。

<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> 

插入腳本也應該被改變:)

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(); 
    } 
}
