提交不顯示數據

Question

我試圖創建一個PHP/MySQL的測驗時動態生成的單選按鈕形式...

我已創建了答案單選按鈕形式顯示從數據庫中取出的數據作爲單選按鈕的值。我試圖提交表單，但結果頁面沒有顯示任何內容。

我測驗的代碼去如下：提交頁面

<form method="post" action="insertscore.php" name="cssCheckbox" id = "cssCheckbox"> 
<?php $query = "SELECT * FROM questions WHERE (`topics` = '.NET' OR `topics` = 'PHP') ORDER BY Rand() LIMIT 5"; $result = mysql_query($query); 

if ($result && mysql_num_rows($result)) { 
    $numrows = mysql_num_rows($result); 
$count =1; 

while ($row = mysql_fetch_array($result)) 
{ 
?> 

<div class="group"> 
<input type="hidden" name="<?php echo $row['key_id']; ?>"><?php $row['key_id']; ?></input> 
<span class="test_question"><strong><?php echo $count;?>) <?php echo $row['question']; ?> 
</strong><br /> 

<?php if($row['answer1'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer1']; ?>" id="chkLimit_1" ></input> 
<label for="chkLimit_1" ><?php echo $row['answer1']; echo "<br />"; } else {} ?></label> 


<?php if($row['answer2'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer2']; ?>" id="chkLimit_2" ></input> 
<label for="chkLimit_2" ><?php echo $row['answer2']; echo "<br />"; } else {} ?></label> 

<?php if($row['answer3'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer3']; ?>" id="chkLimit_3" ></input> 
<label for="chkLimit_3" ><?php echo $row['answer3']; echo "<br />"; } else {} ?></label> 

<?php if($row['answer4'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer4']; ?>" id="chkLimit_4" ></input> 
<label for="chkLimit_4" ><?php echo $row['answer4']; echo "<br />"; } else {} ?></label> 

<?php if($row['answer5'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer5']; ?>" id="chkLimit_5" ></input> 
<label for="chkLimit_5" ><?php echo $row['answer5']; echo "<br />"; } else {} ? ></label> 

<?php if($row['answer6'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer6']; ?>" id="chkLimit_6" ></input> 
<label for="chkLimit_6" ><?php echo $row['answer6']; echo "<br />"; } else {} ?></label> 

<?php if($row['answer7'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer7']; ?>" id="chkLimit_7" ></input> 
<label for="chkLimit_7" ><?php echo $row['answer7']; echo "<br />"; } else {} ?></label> 

<?php if($row['answer8'] != NULL){ ?> 
<input type = "radio" name="answers" value="<?php echo $row['answer8']; ?>" id="chkLimit_8" ></input> 
<label for="chkLimit_8" ><?php echo $row['answer8']; echo "<br />"; } else {} ?></label> 

<input type="hidden" name="<?php echo $row['right_answer']; ?>"><?php $row['right_answer']; ?></input> 
</div> 
<input name="Submit" type="submit" value="Submit Your Answers" class="submit"> 

</form> 

代碼如下所示：

<?php 

if(isset($_POST['Submit'])){ 

$key_id=$_POST['key_id']; echo $key_id; 

$question=$_POST['question']; echo $question; 

$answers=$_POST['answers']; echo $answers; 

$correctanswer=$_POST['correctanswer']; echo $correctanswer; 

} 


foreach($_POST as $key => $val) 
{ 
echo "$key --> $val<br />"; 
} 


//var_dump($_POST); 
?> 

請讓我知道如果有什麼不明確或者如果我缺少什麼？ 。

感謝，

Answer 1

我想：

1. 刪除評論//var_dump($_POST);並在代碼的頂部上提交頁移動這條線。

2. 如果您仍然看不到任何東西，我認爲提交頁面上的代碼不在insertscore.php文件中，或者此文件不在您的表單頁面的同一文件夾中。
