如何从具有不同 URL 的网页访问 cookie 信息

Question

我的代码设置了一个cookie，如下所示；我无法从具有不同 URL 的页面获取 cookie 信息...我的代码有问题吗？如果您有任何问题，请告诉我。

zzz.php;

  setcookie ("mail", $mail, time()+3600*24*365*10);
  setcookie ("name", $name, time()+3600*24*365*10);
  setcookie ("password", $password, time()+3600*24*365*10);
  .....
  http_response_code(301);
  header("Location: ../xxx.php");

xxx.php;

echo $_COOKIE['mail'];

在 xxx.php 上，没有出现。

Answer 1

http://php.net/setcookie

The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain. If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain. The default value is the current directory that the cookie is being set in.

如果您希望 cookie 在父目录中可用，则需要设置 cookie 的路径。最简单的方法是将所有 cookie 设置为路径 /，这样 cookie 在该域的任何地方都可用：

setcookie ("mail", $mail, time()+3600*24*365*10, '/');
setcookie ("name", $name, time()+3600*24*365*10, '/');
setcookie ("password", $password, time()+3600*24*365*10, '/');
