我正在使用EllisLab的应用程序框架。我在登录时遇到问题。$_POST 方法不会在表单提交时存储数据。我在提交表单时收到以下错误。请注意，var_dump（$POST） 返回 array（0）{}
错误屏幕截图
以下是登录页面代码

<form action = "<?php echo base_url();?>admin/login" method = "POST">

?>您在管理控制器或文件中调用登录函数，因此 $_POST 值将数据保存在控制器内，并且您在模型中使用 $_POST 是不可能的。 你必须在控制器中使用 $_POST，而不是像 Panamaldeniya 所说的那样将变量传递给你的模型@Kanishka。
我调试了很多帖子表单。相信我，它是由浏览器发送到您的脚本的。如果您不确定出了什么问题，请运行浏览器调试器（F11 或 Ctrl + Shift + I），以查看您的请求真正发送到您的脚本的内容。另外，如上所述，$_POST是一个 register_global ，因此它在每个php文件中都设置，无论您来自哪里或已经包含多少个文件。也许您的框架获得了您需要的所有参数的请求对象？请先看看...
