PHP通过标头重定向传递变量 [英] PHP passing a variable with header redirect

问题描述

我正在尝试在标头链接中传递变量.我尝试了下面的代码

I am trying to pass a variable within a header link. I have tried below code

$name = "mike";

if($name != "lopan"){
        header("Location:error-page.php?$errorMssg=Please enter information?");
}

此页面重定向到位置，但未传递包含消息的变量.但是，当我用这样的值创建一个简单的链接时:

This page redirect to location but doesn't pass the variable that contains the message. But when i create a simple link with values like this:

<a href="error-page.php?$errorMssg=so what happened there buddy?">link</a>

它通过就可以了.

有什么主意我做错了吗?还是我无法通过标题传递信息?

Any ideas what i am doing wrong? or i can not pass information with headers?

推荐答案

您需要使用 urlencode 像这样:

if($name != "lopan"){
        header("Location:error-page.php?errorMssg=".urlencode("Waoo so your not EVEN going to try to enter information huh?"));
}

在error-page.php中，您应该得到它(无需urldecode):

And in error-page.php, you should get it (no need to urldecode):

<?php
$errorMssg = $_GET['errorMssg'];
