rt，就是说我有一个a.html，里面有一句是
<form action="check.php" method="post">
登陆成功<br>
<input type="hidden" name="name" value="aaa">
<input type="submit" value="继续">
</form>
然后check.php里是
<html>
<head>
<meta charset=utf-8>
</head>
<body>
<?php
$ck=$_POST["name"];
echo $ck;
$aaa="，欢迎您！";
echo $aaa;
echo "<br>";
echo '<form action="s.php" method="post">';
echo '<input type="hidden" name="name" value="'.$ck.'">';
echo '<input type="submit">';
echo '</form>';
?>
</body>
</html>
s.php里是
<html>
<head>
<meta charset=utf-8>
</head>
<body>
<?php
$op=$_POST["name"];
echo '<form action="check.php">';
echo '<input type="hidden" name="name" value="'.$op.'">';
echo '<input type="submit" value="返回">';
echo '</form>';
?>
</body>
</html>
而在进行a.html->check.php->s.php->check.php,到第四步是就无法读取s.php传送给check.php的name了，而第二步时可以读取a.html传送过来的name
大佬求解！！！
