问题描述
我在想一个系统，允许用户每20分钟只发布一篇文章。我不使用成员系统，所以我想我可以设置一个cookie为20分钟。并且当用户发布的东西检查是否设置cookie如果是显示消息像只有一个帖子每20分钟允许如果它不设置为数据库中的东西。
I was thinking of a system that will allow users to post only 1 article per 20 min. I don't use a member system so I thought I could set a cookie for 20 min. And when user posts something check if cookie is set if yes show message like "Only 1 post per 20 min allowed" if it is not set than put stuff in database.
我对php相对较新，不知道如何设置cookie，我试图查看关于cookies的php.net手册，但它对我来说太混乱了。所以，你可以展示如何设置一个安全的cookie为20分钟，并检查它是否或未设置。
I'm relatively new to php and don't know how to set cookies, I tried looking at php.net manual on cookies, but it was too confusing for me. So can you please show how to set a secure cookie for 20 min and check if it is or is not set. Maybe you have Better suggestions that will work instead of cookies etc.
谢谢。
推荐答案
查看这些函数：
- setCookie
- get cookie value
要将Cookie设置为20分钟，您可以执行以下操作：
To set a cookie for 20 min you can do this:
setcookie("postedArticle", true, time() + (60 * 20)); // 60 seconds ( 1 minute) * 20 = 20 minutes
检查是否设置了cookie： p>
Check if cookie is set:
if(isset($_COOKIE['postedArticle']) && $_COOKIE['postedArticle'] == true)
{
// IS SET and has a true value
}
