在我的主题的 header.php 中，但是当我转到浏览器查看我的网站时出现此错误

in header.php of my theme, but when I go to my browser to view my website I get this error

Warning: Cannot modify header information - headers already sent by (output started at /home/content/19/9468119/html/wp-content/themes/twentyeleven/header.php:27) in /home/content/19/9468119/html/wp-content/themes/twentyeleven/header.php on line 201

and also my cookie doesnt set. How do I set a cookie in wordpress?

我也试过这个

 function set_new_cookie() {
    setcookie('test', 'test', 0, '/', '/');
}
add_action( 'init', 'set_new_cookie');

推荐答案

你必须在输出任何东西之前设置它们

You have to set them before anything is outputted

看那里:如何设置，获取并销毁 Wordpress 中的 cookie?

如果您在 function.php 中使用主题

If you are using a theme in function.php

function set_new_cookie() {
    //setting your cookies there
}
add_action( 'init', 'set_new_cookie');

您的到期日期日期为 0，因此您的 cookie 将立即被删除，请查看 php 文档:

Your expiration date is 0 so you cookies will be deleted right away look at the php doc:

来自 php.net:

From php.net:

如果设置为 0 或省略，cookie 将在结束时过期会话(当浏览器关闭时).

If set to 0, or omitted, the cookie will expire at the end of the session (when the browser closes).

http://php.net/manual/en/function.setcookie.php

你必须像这样设置它，例如:

You have to set it like this for example :

setcookie("TestCookie", $value, time()+3600);  /* expire in 1 hour */
