You have to set them before anything is outputted
您必须在输出任何内容之前设置它们
look there: How can I set, get and destroy cookies in Wordpress?
看看那里：如何在 Wordpress 中设置、获取和销毁 cookie？
If you are using a theme in function.php
如果您在 function.php 中使用主题
function set_new_cookie() {
//setting your cookies there
}
add_action( 'init', 'set_new_cookie');
Your expiration date is 0so you cookies will be deleted right away look at the php doc:
您的到期日期为 0，因此您的 cookie 将立即被删除，请查看 php 文档：
EDIT: From php.net:
编辑：来自 php.net：
If set to 0, or omitted, the cookie will expire at the end of the session (when the browser closes).
如果设置为 0 或省略，cookie 将在会话结束时过期（当浏览器关闭时）。

You have to set it like this for example :
例如，您必须像这样设置它：
setcookie("TestCookie", $value, time()+3600); /* expire in 1 hour */

Setting a Cookie: The below example will set the cookie that expired for one hour (60*60 seconds)since it set with COOKIEPATHand COOKIE_DOMAINwas defined by WordPress according to your site path and domain.
setcookie( 'my-cookie-name', 'my-cookie-value', time() + 3600, COOKIEPATH, COOKIE_DOMAIN );Getting a Cookie: Getting a cookie can be done by using variable $_COOKIE which contains an associative array.
$myCookie = isset( $_COOKIE['my-cookie-name'] ) ? $_COOKIE['my-cookie-name'] : 'Not Set!!';Delete or Unset a Cookie: It is same as the above instruction #1, just with a negative time to expire the cookie;
setcookie( 'my-cookie-name', '', time() - 3600, COOKIEPATH, COOKIE_DOMAIN );
设置 Cookie：下面的示例将设置过期一小时（60*60 秒）的 cookie，因为它设置了COOKIEPATH并且COOKIE_DOMAIN是由 WordPress 根据您的站点路径和域定义的。
setcookie( 'my-cookie-name', 'my-cookie-value', time() + 3600, COOKIEPATH, COOKIE_DOMAIN );获取 Cookie：可以通过使用包含关联数组的变量 $_COOKIE 来获取 cookie。
$myCookie = isset( $_COOKIE['my-cookie-name'] ) ? $_COOKIE['my-cookie-name'] : 'Not Set!!';删除或取消设置cookie：与上述指令#1 相同，只是cookie 过期时间为负数；
setcookie( 'my-cookie-name', '', time() - 3600, COOKIEPATH, COOKIE_DOMAIN );
