注意：未定义的索引...... [英] Notice: Undefined index...

问题描述

我最近在生产网站上发现了我的错误报告

到E_ALL，以确保我在编写代码时使用''最佳实践''。


到目前为止，它已经帮助我训练自己初始化我的

变量。我遇到了我的$ _POST数组的问题。


我自我引用一个表单页面进行处理，所以在开始时我

am寻找某些$ _POST变量的存在进行处理。


我将''action''字段设置为''login''例如。


我已经多次这样做了没有问题，即使在这个

的情况下也没有致命的错误。然而，我收到一条通知，我正在查看我的

$ _POST变量是未申报的。


注意：未定义的索引：动作


我无法在

检查之前公开看到一种声明$ _POST [''action'']的方法，因为它是由服务器设置的，当页面是这是我的实际代码片段：


if（$ _ POST [''action''] ===''登录''）{

//处理数据//

}


我是否需要学习忽略此特定错误或有什么东西

我没看到？


谢谢

I have since recently turned up my error reporting on a production site
to E_ALL to ensure I am using ''best practices'' when writing out code.

So far it has helped me discipline myself with initializing my
variables. I am running into a problem with my $_POST array though.

I am self-referencing a form page for processing, so at the beginning I
am looking for the existence of certain $_POST variables for processing.

I am setting an ''action'' field to ''login'' for example.

I have done this on several occasions with no problems and even in this
case there is no fatal error. I am however receiving a NOTICE that my
$_POST variables I am looking at is undeclared.

"Notice: Undefined index: action"

I cannot openly see a way to declare the $_POST[''action''] prior to
checking it since it is set by the server when the page is loaded.

Here is my actual code snippet:

if($_POST[''action''] === ''login'') {
//process data//
}

Will I need to learn to ignore this specific error or is there something
I am not seeing?

Thanks
Scotty
