推荐答案
您可以使用JavaScript在服务器端使用PHP或客户端检索和操作Cookie。
You can either retrieve and manipulate cookies on the server side using PHP or client side, using JavaScript.
在PHP中,您可以使用 setcookie( )
。注意,这必须在任何输出发送到浏览器之前完成,这可能是Wordpress中的相当大的挑战。你非常局限于一些早期运行钩子,你可以通过插件或主题文件( functions.php
)设置,例如
In PHP, you set cookies using setcookie()
. Note that this must be done before any output is sent to the browser which can be quite the challenge in Wordpress. You're pretty much limited to some of the early running hooks which you can set via a plugin or theme file (functions.php
for example), eg
add_action('init', function() {
if (!isset($_COOKIE['my_cookie'])) {
setcookie('my_cookie', 'some default value', strtotime('+1 day'));
}
});
在PHP中检索Cookie更容易。只需从 $ _ COOKIE
超级全局名称获取它们,例如
Retrieving cookies in PHP is much easier. Simply get them by name from the $_COOKIE
super global, eg
$cookieValue = $_COOKIE['my_cookie'];
取消设置Cookie需要设置过去的过期日期,例如
Unsetting a cookie requires setting one with an expiration date in the past, something like
setcookie('my_cookie', null, strtotime('-1 day'));
在一个jQuery cookie插件(看作为jQuery已经是Wordpress的一部分)。尝试 http://plugins.jquery.com/project/Cookie
