我的代码似乎不起作用..单选按钮出现，但旁边什么也没有..似乎 mysql_fetch_array 由于某种原因无法工作，因为我已经玩过代码并反复测试它以查找代码似乎遇到的位置出现问题并停止工作..有人可以告诉我出了什么问题吗？欢呼声我是新手，最近几天才完成 w3schools 上的 php 教程。
<body>
<?php
include 'dbyear2.php';
$qnumber = $_REQUEST['uqn']; // obtain question number from URL
$find = mysql_query("SELECT * FROM Renal WHERE UQN='$qnumber'");
while($retrieve=mysql_fetch_array($find));
{
$retrieve['question'] = $question;
$retrieve['MCQ_A'] = $a;
$retrieve['MCQ_B'] = $b;
$retrieve['MCQ_C'] = $c;
$retrieve['MCQ_D'] = $d;
$retrieve['MCQ_E'] = $e;
$retrieve['answer'] = $answer;
$retrieve['MCQ_correct'] = $correct;
}
?>
<form action='check.php' method='POST'>
<table>
<tr><td></td><td></td></tr>
<tr></tr>
<tr><td><input type='radio' name='group1' value='A' /></td><td> <?php echo $a; ?></td></tr>
<tr><td><input type='radio' name='group1' value='B' /></td><td> <?php echo $b; ?></td></tr>
<tr><td><input type='radio' name='group1' value='C' /></td><td> <?php echo $c; ?></td></tr>
<tr><td><input type='radio' name='group1' value='D' /></td><td> <?php echo $d; ?></td></tr>
<tr><td><input type='radio' name='group1' value='E' /></td><td> <?php echo $e; ?></td></tr>
<tr>
<?php
// sending the retrieved information from MYSQL via POST for use in check.php file
$qnumber;
$a;
$b;
$c;
$d;
$e;
$answer;
$correct;
?></tr>
<tr><td><input type="submit" value="Submit"></td></tr>
</table>
</form>
</body>
</html>
这部分是向后的：
$retrieve['question'] = $question;
$retrieve['MCQ_A'] = $a;
$retrieve['MCQ_B'] = $b;
$retrieve['MCQ_C'] = $c;
$retrieve['MCQ_D'] = $d;
$retrieve['MCQ_E'] = $e;
$retrieve['answer'] = $answer;
$retrieve['MCQ_correct'] = $correct;
应该
$question = $retrieve['question' ;
$a = $retrieve['MCQ_A'];
$b = $retrieve['MCQ_B'];
$c = $retrieve['MCQ_C'];
$d = $retrieve['MCQ_D'];
$e = $retrieve['MCQ_E'];
$answer = $retrieve['answer'];
$correct $retrieve['MCQ_correct'];
