$ _POST在提交web应用程序时未存储数据

我正在使用EllisLab的应用程序框架。我有问题登录。$ _POST方法不在表单提交中存储数据。表单提交时出现以下错误。注意的var_dump（$ POST）返回阵列（0）{}

下面是登录页代码

<html> 
 
<head> 
 
\t <title> Control Panel</title> 
 
</head> 
 

 
<body> 
 
\t <form action = "<?php echo base_url();?>admin/login" method = "POST"> 
 
\t <table> 
 
\t \t <tr> 
 
\t \t \t <td> Username : </td> 
 
\t \t \t <td> <input type = "text" name = "username" id = "usr"/> </td> 
 
\t \t </tr> 
 

 
\t \t <tr> 
 
\t \t \t <td> Password : </td> 
 
\t \t \t <td> <input type = "password" name = "password" id = "pass"/> </td> 
 
\t \t </tr>

你的控制器呢？ –

删除HTML中'='之间的空格。。并显示你的控制器。 –

把你的控制器代码并尝试$ this-> input-> post（'yourfieldname'）;在您的模型中 –

您呼叫登录功能在你的管理控制器或文件，因此$ _ POST值保存控制器内的数据，并且您在MODEL中使用$ _POST而不是可能的。你必须在你的控制器中使用$ _POST，而不是像@Kanishka Panamaldeniya所说的那样将变量传递给你的模型。

我调试了很多表单。相信我，它会被浏览器发送到您的脚本。如果您不确定，出了什么问题，请运行浏览器调试程序（F11或Ctrl + Shift + I），查看您的请求实际发送给脚本的内容。另外，如上所述，$_POST是register_global，所以它被设置在每个php文件中，无论你来自哪里，或者有多少文件已经包含在内。也许你的框架得到了你需要的所有参数的请求对象？请先看看它...

username = admin＆password = password＆submit =登录 –

这些位于标题中的表单数据字段中。使用Chrome浏览器调试器。 –

$ _POST在提交web应用程序时未存储数据
