$ _POST不在提交的Web应用程序上存储数据

标签： javascript php jquery html forms

我使用的是EllisLab的应用程序框架。我有登录问题。$ _POST方法没有在表单提交上存储数据。我在表单提交时收到以下错误。请注意，var_dump（$ POST）返回array（0）{}

以下是登录页面代码

2 个答案:

答案 0 :(得分：0)

您正在管理控制器或文件中调用登录功能，因此$ _POST值保存控制器内的数据，并且您在MODEL中使用$ _POST是不可能的。你必须在你的控制器中使用$ _POST，而不是像@Kanishka Panamaldeniya那样将变量传递给你的模型。

答案 1 :(得分：0)

我调试了很多帖子。相信我，它将由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register_global，因此无论您来自何处或已经包含了多少个文件，它都会在每个php文件中设置。也许你的框架得到了你需要的所有参数的请求对象？请先看一下......
