提交不显示数据

Question

我试图创建一个PHP/MySQL的测验时动态生成的单选按钮形式...

我已创建了答案单选按钮形式显示从数据库中取出的数据作为单选按钮的值。我试图提交表单，但结果页面没有显示任何内容。

我测验的代码去如下：提交页面

<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> 

代码如下所示：

<?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); 
?> 

请让我知道如果有什么不明确或者如果我缺少什么？ 。

感谢，

Answer 1

我想：

1. 删除评论//var_dump($_POST);并在代码的顶部上提交页移动这条线。

2. 如果您仍然看不到任何东西，我认为提交页面上的代码不在insertscore.php文件中，或者此文件不在您的表单页面的同一文件夹中。
