是否可以设置一个cookie到会话变量的无限时间？ [英] is it possible to set unlimited time for a cookie to a session variable?

问题描述

如何为会话设置无限时间的Cookie？我已经尝试以下，但我仍然得到未定义的索引通知在我的会话一天后：

How do I set unlimited time to a cookie for a session? I have tried the following below but I still get undefined index notices on my sessions after a day:

setcookie('idcourse', 'CourseID', 9999999999);
setcookie('namecourse', 'CourseName', 9999999999);
setcookie('id', 'ID', 9999999999);

if (isset($_POST['idcourse'])) {

$_SESSION['idcourse'] = $_POST['idcourse'];

}

if (isset($_POST['namecourse'])) {

$_SESSION['namecourse'] = $_POST['namecourse'];

}

if (isset($_POST['id'])) {

$_SESSION['id'] = $_POST['id'];

}

推荐答案

添加到期日期，或者Cookie将像会话一样，并在您离开网站时过期。

You must add an expiry date, or the cookie will act like a session and expire when you leave the website,

您正在做的是几乎正确的，但您需要更改

what you're doing is nearly right but you need to change it slightly;

您设置的过期日期为9999999999（您需要在将来指定UNIX TIMESTAMP），因此我使用以下命令：

You are setting expire 9999999999 (you need to specify a UNIX TIMESTAMP in the future), so i use the following:

$inTwoMonths = 60 * 60 * 24 * 60 + time();
setcookie('idcourse', 'CourseID', $inTwoMonths );
setcookie('namecourse', 'CourseName', $inTwoMonths );
setcookie('id', 'ID', $inTwoMonths );

将使cookie在2个月内过期，您可以相应地增加此值。

will make the cookie expire in 2 months, you can increment this accordingly.
