设置cookie wih JS，读取PHP问题 [英] Set cookie wih JS, read with PHP problem

问题描述

我尝试用javascript设置cookie，并在php的其他页面中读取。
我可以通过执行

I'm trying to set a cookie with javascript and read it in an other page with php. I am able to write the cookie by doing

document.cookie = cookieName+"="+cookieValue;

和i部分工作。 - 写的cookie，我可以用 $ _ COOKIE [cookieName] 阅读，但只能在同一个网页上。

and i partially works. - The cookie is written, and I am able to read it with $_COOKIE[cookieName] but ONLY in the same web page.

这真的不是很有用。我需要在另一个页面读它。我通常在asp.net和c＃开发，所以我preper新的php。我会做错事吗？

Which is not quite usefull really. I need to read it in another page. I usually develop in asp.net and c#, so I'm preety new to php. Am I doing something wrong?

感谢您的时间！

EDIT1：
在同一个域。 site.com/index.php - > site.com/index2.php

both pages are in the same domain.. eg. site.com/index.php -> site.com/index2.php

EDIT2：
在一页中设置Cookie：

the cookie is set in one page through:

function SetCookie(cookieName,cookieValue,nDays) {
 var today = new Date();
 var expire = new Date();
 if (nDays==null || nDays==0) nDays=1;
 expire.setTime(today.getTime() + 3600000*24*nDays);
 document.cookie = cookieName+"="+escape(cookieValue)
                 + ";expires="+expire.toGMTString();
}

在另一个页面中无法访问，但在同一页面可以...

and in another page it can not be accessed, but in that same page it can...

EDIT3：
i尝试设置域并添加 path =<？php echo $ _SERVER ['HTTP_HOST' ];

i tried setting the domain and added path=<?php echo $_SERVER['HTTP_HOST']; ?> to the javascript code... still nothing..

EDIT4：
到目前为止我有..

so far I have..

document.cookie = cookieName+"="+escape(cookieValue)+"; expires="+expire.toGMTString()+"; path=/"+"; domain=.<?php echo $_SERVER['HTTP_HOST']; ?>";

，仍然可以从同一页面读取cookie。

and still i can read the cookie ONLY from the same page..

EDIT5：
oh .. my .. god ...这是一个错字，只是需要删除path = / +<强...>我很羞愧自己现在...
在此期间我还重置了我的饼干，所以Jared现在我不幸地不能接受你的帖子作为anwser ... $

oh.. my .. god... it was a typo all along... just needed to remove the" path=/"+"; dom..." i am so ashamed of myself right about now... in the meantime i also reset my cookies, so Jared now i unfortuneatly can't accept your post as anwser... i brought shame upon my name!!!....

推荐答案

阅读设置Javascript Cookie，特别是路径和域访问权限：

Read on setting Javascript cookies and in particular path and domain access here:

http://www.quirksmode.org /js/cookies.html

我认为发生的是以下两种情况之一：

I think what is happening is one of two things:

1. 您不是从同一个域/子域访问Cookie，和/或


2. 另一个网页不是Cookie指定的路径的一部分。

因此，您的Cookie未向浏览器提供相关信息，以便通过子域和/或目录路径访问。 / p>

So your cookie is not giving the relevant information to the browser for it to be accessible across subdomains and/or the directory path.

document.cookie = 'ppkcookie1=testcookie; expires=Thu, 2 Aug 2001 20:47:11 UTC; path=/; ;domain=.example.com'

注意， .example.com 只是一个示例域（您需要您的域），并且不需要除了初始之外的通配符。 。您需要生成 expires = 日期。从QuirksMode：

Note, .example.com is just an example domain (you need yours in there), and you do not need a wildcard other than the initial . for it go across all subdomains. And you need to generate an expires= date. From QuirksMode:

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    } else {
        var expires = "";
    }
    document.cookie = name+"="+value+expires+"; path=/; domain=.example.com";
}

我添加了 domain =

I added the domain= bit to QuirksMode's function.

Andrej，对我来说完全正常：

Andrej, this works perfectly fine for me:

http://example.com/test.php

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/; domain=.example.com";
}

createCookie('cookieee','stuff','22');

http ：//example.com/test/test.php

<pre>
<?php 

print_r($_COOKIE);

?>

并且 $ _ COOKIE 的打印输出cookie。注意我在检查Cookie时，将.example.com设置为域正确。

And the printout of $_COOKIE will show the cookie. Note I when I inspect the cookie the .example.com is set correctly as the domain.
