从IE8发布到PHP会产生空白$ _POST [英] Posting from IE8 to PHP gives blank $_POST
问题描述
我有一个简单的HTML表单，向php脚本发送一个post请求。在IE8中，表单只能间歇性地工作 - 大多数时候PHP脚本看到一个空的$ _POST变量。
这是我的代码：
< html>
< head>
< title>测试后< / title>
< / head>
< body style =text-align：center;>
<？php
echo< pre>。print_r（$ _ POST，TRUE）。< / pre>;
？>
< form action =<？php echo $ _SERVER ['PHP_SELF']？>方法= POST >
< input type =textname =name>
< input type =hiddenname =hiddenvalue =moo>
< input type =submitvalue =搜索>
< / form>
< / body>
< / html>
有时print_r会给出您期望的响应（即它填充了表单中的数据） ，大部分时间都是空的。
无法使用POST对于网络应用程序来说有点问题 - 任何人都知道发生了什么，以及如何修复它？
感谢大家趟这个。
<事实证明问题出在我启用的Apache模块中。
这是一个允许apache使用Windows身份验证通过Windows用户ID识别用户的模块 - mod_auth_sspi
效果是由模块中的已知错误引起的，但是有一个简单的额外指令可以解决这个问题，直到下一次添加修复更新，如下所述：

I have a simple HTML form, sending a post request to a php script. In IE8, the form only works intermittently - most of the time the PHP script sees an empty $_POST variable.
Here's my code:
<html>
<head>
<title>Post test</title>
</head>
<body style="text-align: center;">
<?php
echo "<pre>".print_r($_POST, TRUE)."</pre>";
?>
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<input type="text" name="name">
<input type="hidden" name="hidden" value="moo" >
<input type="submit" value="Search" >
</form>
</body>
</html>
Sometimes the print_r gives the response you'd expect (i.e. it's populated with the data from the form), most of the time it's empty.
Not being able to use POST is a bit of a problem for web applications - anyone got any ideas what's going on, and how to fix it?
Thanks everyone for wading in on this one.
It turns out the problem lay in an Apache module I had enabled.
It's a module to allow apache to use Windows authentication to identify a user via their Windows User id - mod_auth_sspi
The effect is caused by a known bug, in the module, but with a simple extra directive this can be worked around, until a fix is added in the next update, as described here:
