<table width="284" border="1" cellpadding="0" cellspacing="0">

<td height="25" align="center" class="style1"><?php echo "管理员:$username"?></td>
</tr>
<tr>
<td height="25" align="center" valign="middle" class="style1"><?php echo "密码:$password";?></td>
</tr>
</table>
</body>

这段代码在我电脑上运行没有出错 可为什么输入管理员姓名和密码再点提交后，没有在该显示的地方显示出来姓名和密码呢？
if($Submit=="提交"){
$username=$_POST[username];
$password=$_POST[password];
}
?>

// 第一行内容修改为：
if($_POST['Submit']=="提交"){
$username=$_POST[username];
$password=$_POST[password];
}
if($_POST['Submit']=="提交"){
$username=$_POST[username];
$password=$_POST[password];
}
