我以前试过这个问题，但没有提供足够的信息，所以这里有更多的细节。我在一个托管网站上有一个页面，要求访问者在表单中输入一个编码字符串。提交后，代码会生成一个文件名，并从文本文件中获取一些简单的数据。
在FF和Safari中一切都很好，但在internet explorer 7和internet explorer 8中测试时，提交后，访问者会重定向到网站主页。
同样的意外重定向也发生在网站的其他地方。我希望如果我能在这里隔离这个问题，我就能修复其他实例。
这是代码：
<?php
session_start();
ob_start;
?>

您在创建FORM元素的同一行关闭它：
<form method="POST" action="<?php $_SERVER['PHP_SELF'] ?> " />
将其更改为：
<form method="POST" action="<?php $_SERVER['PHP_SELF'] ?> ">
我不确定这会具体解决你的重定向问题，但我知道如果你不解决这个问题，它会导致你的表单提交出现一些问题。
编辑
好吧，我第一次忽略了这个问题，这里是修复方法，更改上面列出的同一行代码，但包括echo。。。
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
或者简化：
<form method="POST" action="<?=$_SERVER['PHP_SELF']?>">
