已解决:我省略了输入字段上的名称属性。我有一个简单的 html/php -form。我提交它。$_POST 始终为空。如果我尝试获取,那么 GET 始终为空。$_REQUEST 和 php://input 相同。我什么也得不到。
有很多关于这个主题的帖子,但我还没有找到解决我问题的方法。我没有重写或重定向。method_request 是 POST。表单中的 id 没有冲突,php://input 也是空的,REQUEST 也是空的。我已将 Suhosin.simulation 开启,这意味着它无法正常工作。POST_MAX_SIZE = 16M。对于两个小文本应该足够了。
php.ini 变量 request_order 和 variable_order 分别是 GP 和 GPS。Magic_quotes_gpc 已关闭。默认 mime-type = text/html 并且每个页面都有字符集 UTF-8。函数 php_sapi_name() 的结果是 apache2handler。
PHPVersion = 5.3,Suhosin - 补丁 0.9.1。操作系统 = Ubuntu 12.04 LTS,Apache = 2.2.22。
这里有两个文件。我对它们进行了一些简化,但通常它们可以正常工作。我有 GET 方法的类似文件。

$_POST 数据应该发送到的另一个文件:

www.thuis.lb 是本地服务器的名称。它的 IP 为 127.0.0.1。Thuis 是荷兰语,意为在家。有什么我忘记了或者我做错了什么吗?
编辑:更多信息。在更复杂的第一个 php 中,存在与数据库的信息交换。这就像一个魅力。完全没有问题。因此,我认为这个问题是一个安全问题。我将为 www.thuis.lb 添加虚拟主机文件。虽然它几乎就像默认的虚拟主机,但它可能是问题所在。
<VirtualHost thuis.lb:80>

编辑二:我可以添加更多信息。在访问日志中有例如这一行: 127.0.0.1 - - [04/Apr/2013:11:13:43 +0200] "POST /testPost_2.php HTTP/1.1" 200 2020 " http://www. thuis.lb/testPost.php " "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0"。这表明 imo apache2 正在以良好的状态接收帖子。但是 PHP 中的 $_POST 仍然是完全空的。在 Firebug>Net>Headers 的显示中是 Content Length 0。
