这是我在function.php中的函数的开头（现在，它是完整的代码，根据帮助请求）我疯了因为如果我使用相同的get_post_meta OUTSIDE函数INSIDE functions.php =＆gt;只要我传递正确的帖子ID，它就能很好地工作。但是一旦它在钩住的函数内部（是的，有一个钩子，其余部分完美地工作）它不会返回一个值。请帮忙

Answer 1

您可能需要将$post传递给该函数以及$post_id。尝试将第一行更改为：

function notify_new_posts( $post_id, $post ) {

参考：http://codex.wordpress.org/Plugin_API/Action_Reference/publish_post

Answer 2

使用global $post;

例如：

function notify_new_posts($post_id) {
global $post;

get_post_meta不在functions.php中的函数内部工作，但在外部工作
