我编写了一个简单的插件，可以在帖子发布时获取帖子的内容，并将其发送到外部站点进行归档。这通常是可行的，但当处理以前没有保存或发布的帖子时，没有post_content 值可用。如果在发布之前另存为草稿，则所有操作都正常，只有在直接发布时，该值才为空。

我的插件是这样的：

function send_data($postID,$post){
  global $post;
  print_r($post); //used for debugging the contents of $post
  //stuff here to send the post for archiving
}
add_action(\'publish_post\',\'send_data\',2);

如果一切顺利，我将此作为$post的内容：

WP_Post Object ( [ID] => 159 [post_author] => 1 [post_date] => 2013-01-30 09:11:05 [post_date_gmt] => 0000-00-00 00:00:00 [post_content] => This is the content of the post [post_title] => Something new [post_excerpt] => [post_status] => draft [comment_status] => open [ping_status] => open [post_password] => [post_name] => [to_ping] => [pinged] => [post_modified] => 2013-01-30 09:11:05 [post_modified_gmt] => 2013-01-30 09:11:05 [post_content_filtered] => [post_parent] => 0 [guid] => http://wordpress/?p=159 [menu_order] => 0 [post_type] => post [post_mime_type] => [comment_count] => 0 [filter] => raw )

但是，如果我直接从创建帖子内容跳到“发布”按钮，我会得到一个空值$post->post_content:

WP_Post Object ( [ID] => 159 [post_author] => 1 [post_date] => 2013-01-30 09:11:05 [post_date_gmt] => 0000-00-00 00:00:00 [post_content] => [post_title] => Something new [post_excerpt] => [post_status] => draft [comment_status] => open [ping_status] => open [post_password] => [post_name] => [to_ping] => [pinged] => [post_modified] => 2013-01-30 09:11:05 [post_modified_gmt] => 2013-01-30 09:11:05 [post_content_filtered] => [post_parent] => 0 [guid] => http://wordpress/?p=159 [menu_order] => 0 [post_type] => post [post_mime_type] => [comment_count] => 0 [filter] => raw )

有没有人想过我该如何让这更可靠？有钩子吗after_publish_post 或者类似的东西？

任何想法都很感激。
