今天写了一个php注册的代码这个事登陆后的代码，能实现：
<?php session_start(); if($_SESSION["name"]==""){echo "<script>location.href='index.php';</script>";exit;
}
//上面的要验证过滤的
?><html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>管理页面</title>
<style type="text/css">
<!--
.style1 {color: #009900}
-->
</style>
</head><body><center>
<p> </p>
<p> </p>
<p> </p>
<table width="58%" height="186" border="0" cellpadding="0" cellspacing="2" bgcolor="#FFFFFF">
<tr>
<td align="center" bgcolor="#CCCCCC"><strong>管理中心</strong>(display.php)</td>
</tr>
<tr>
<td align="center" bgcolor="#CCCCCC"><?php echo $_SESSION["name"]?><span class="style1">欢迎您的到来</span>！</td>
</tr>
<tr>
<td align="center" bgcolor="#CCCCCC"><a href="login_out.php">退出</a>(login_out.php)|<a href="user_edi.php?name=<?php echo $_SESSION["name"]?>">编辑个人资料</a>(user_edi.php)</td>
</tr>
</table>
</center></body>
</html>
下面就是问题：点击编辑个人资料的时候是空白页，（进不了我想要的界面）请高人之处错误之处，小弟万分感谢！
<?php session_start();
if($_SESSION["name"]==""){
echo "<script>location.href='index.php';</script>";
exit;
//这里是SESSION来验证用户的合法性
}
include("config.php");
?>

是说点击这个编辑没有反应吗？没有给加链接啊，如何反应？
1、少了一个冒号， <a href="user_edi.php?name= <?php echo $_SESSION["name"];?>">编辑个人资料 </a>(user_edi.php) </td>
2、没有用<a>和</a>,<td colspan="2"><A href="user_edi.php">编辑</a>(user_edi.php)|| <a href="display.php">返回 </a> </td>
