PHP Cookie不工作 [英] PHP Cookies not working

问题描述

我正在建立一个登入网站。我有会话工作正常，但我需要能够让他们登录，如果点击记住我。目前，我有登录脚本保存一个cookie，用户名和密码他们键入到某些cookie。我下面的脚本$ username和$ password在脚本中设置得更高。 $ _SESSION变量设置得很好。

I am building a website with logins. I have sessions working fine but I need to be able to keep them logged in if the click remember me. Currently I have the login script saving a cookie with the Username and Password they type to some cookies. I the below script $username and $password are set higher in the script. The $_SESSION variables are getting set fine. And I know the script is going into the if statement because before I place a alert box in there.

login.php

login.php

while($row = mysql_fetch_array($getLoginResults))
{
    $error = "Login Successful";
    $_SESSION['Username'] = $_POST['username'];
    $_SESSION['Password'] = $_POST['password'];
    if($keep == 1)
    {
        setcookie("Username", $username, time()+3600*24*30);
        setcookie("Password", $password, time()+3600*24*30);
    }
}

当我检查登录时，所以我knoe的cookie设置，但警报框是空的。

When I check the login, I have a javascript alert so I knoe the cookie is set but the alert box is coming up empty.

check_login.php

check_login.php

echo "<script>alert('".$_COOKIE['Username']."')</script>";

我缺少什么？

推荐答案

尝试使用setcookie与指定的路径，这用于捕获我，因为它假设当前路径默认情况下。使用/将使cookie用于整个域

Try using setcookie with a a path specified, this used to catch me out, as it assumes the current path by default. Using / will make the cookie work for the whole domain

setcookie("Username", $username, time()+3600*24*30, '/');
