我正在使用。。。
function on_CPT_request_publish( $new, $old, $post ) {
// ----------------- Start of Function -----------------
if ( ( $new == \'publish\' ) && ( $old != \'publish\' ) && ( $post->post_type == \'request\' ) ) {
// -------------------- Grab details to work with -----------------------
$RequestID = $post->ID;
$the_book_ID = get_post_meta($RequestID, \'book_id\', true);
// - URL Info - https://developer.wordpress.org/reference/functions/get_post/
// Get Book details
$post_book_details = get_post( $the_book_ID );
$book_title = $post_book_details->post_title;
$the_book_genre_ID = get_post_meta($the_book_ID,\'book_genre\',true);
$theBookAuthor = $post_book_details->post_author;
$your_content = \'the_book_ID = \' . $the_book_ID . \'<br>\';
$your_content = $your_content . \'book_title = \' . $book_title . \'<br>\';
$your_content = $your_content . \'the_book_genre_ID = \' . $the_book_genre_ID . \'<br>\';
$your_content = $your_content . \'theBookAuthor = \' . $theBookAuthor . \'<br>\';
$review_post_id = wp_insert_post(array (
\'post_type\' => \'review\',
\'post_title\' => \'Review of the_book_ID - \' . $post->post_title . \' - Genre - \' . $the_book_genre_ID,
\'post_author\' => $theBookAuthor,
\'post_content\' => $your_content,
\'post_status\' => \'publish\',
\'comment_status\' => \'closed\',
\'ping_status\' => \'closed\',
if ($review_post_id) {
// insert post meta
add_post_meta($review_post_id, \'review_book_id\', $the_book_ID);
add_post_meta($review_post_id, \'book_author_id\', $theBookAuthor);
}
// ----------------- End of Function -----------------
}
}
add_action( \'transition_post_status\', \'on_CPT_request_publish\', 201, 3 );
。。。它正在抓取新创建的帖子的详细信息好的，没问题，但当我尝试访问帖子元时，找不到该信息。
任何get\\u post\\u元数据都不起作用，但我已经检查了数据库，并且我在Posteta中查找的记录已经存在。
我还使用了。。。
function on_CPT_request_publish( $ID, $post ) { code stuff }
add_action( \'publish_request\', \'on_CPT_request_publish\', 10, 2 );
但没什么不同。这是我的主要问题。。。
$the_book_ID = get_post_meta($RequestID, \'book_id\', true);
如果我能让这一行正常工作，其他一切都会好起来的（很好，足以让我完成代码调试）。创建的“review”CPT的内容如下。。。
the_book_ID =
book_title = Book Review Request
the_book_genre_ID =
theBookAuthor = 2
当站点前端的表单创建一个名为“Request”的自定义帖子类型时，我们都在关注的这个函数就会启动。“Request”CPT有一个称为“book\\u id”的元值。这个“book\\u id”元值保存了一个名为books的CPT的post id，而这个“book”CPT保存了有关书籍的所有详细信息，如标题、流派、作者等。
现在，当“请求”CPT完成时，它将图书ID保存在一个名为“book\\u ID”的元标记中，完成“请求”CPT也会启动此功能。此函数需要获取“Request”CPT的刚刚发布的表单详细信息，尤其是post meta中的“book\\u id”。我在用这条线$\\u book\\u ID=get\\u post\\u meta（$RequestID，\'book\\u ID\'，true）。。。要获取要在此处使用的图书ID$post\\u book\\u details=get\\u post（\\u book\\u ID）；获取书籍详细信息。
因此，“book\\u id”是一个post元值，它已经存在于我尝试访问的新创建的“Request”CPT中。
希望这现在更有意义。
帮助

我发现，实际上，在一个新的帖子创作中，帖子元实际上还不可用！我试图得到一些不可用的东西！
检查-How to access the post meta of a post that has just been published? .... 上面说。。。“发布帖子并调用‘publish\\u post’时，帖子元尚未保存在数据库中”。
多亏了Nicolai$_Post[FormFeild] 获取所需的详细信息！
这是我的工作代码，第6行($the_book_ID = $_POST[\'input_2\'];) 一切正常！
function on_CPT_request_publish( $ID, $post ) {
// ----------------- Start of Function -----------------
// -------------------- Grab details to work with -----------------------

$the_book_ID = $_POST[\'input_2\'];
// Get reviewer count
$the_requested_reviews = $_POST[\'input_16\'];
// Grab the number before the pipe for e.g. 3|69 would = 3
$vars = explode(\'|\', $the_requested_reviews);
$the_requested_reviews = $vars[0];
// Get Book details
$post_book_details = get_post( $the_book_ID );
$book_title = $post_book_details->post_title;
$the_book_genre_ID = get_post_meta($the_book_ID,\'book_genre\',true);
$theBookAuthor = $post_book_details->post_author;
