我认为您可以通过以下方式实现这一目标：

1.通过使用get_post_types() 外汇

它根据您传递的参数返回帖子名称或对象的列表

<?php
$args = array(
  \'public\'   => true,
  \'_builtin\' => false
); //pass parameter to array according to get all custom post types( parameter pass for demo only.modify it to get desire result)
$post_types=get_post_types($args,\'names\');

?>

2。发布时向自定义帖子类型添加操作

<?php
foreach($post_types as $post_type){
  add_action( \'publish_\'.$post_type, \'ravs_notify_published_post\' );
}
function ravs_notify_published_post( $post_id ) {
 $post = get_post( $post_id );
 // Here\'s the magic
 Wp_Heartbeat_Notify::notify( array(
    \'title\'     =>      \'New Post by \' . $post->post_author,
    \'content\'   =>      \'There\\\'s a new post publish, why don\\\'t you <a href="\' .get_permalink($post_id). \'">give it</a> a look?\',
    \'type\'      =>      \'info\'
  ));
}
?>

创建插件以显示实时通知WP-Realtime-Notify

Edit

粘贴此代码functions.php.它将打印自定义帖子类型的名称数组。转到get_post_types 并查看所有参数。通过提供所需输出的正确参数（更改$args ).如果您获得了所需的自定义帖子类型名称的正确数组$args,用我的$args 插件中。

<?php
add_action(\'the_content\',\'ravs_customPostList\');
function ravs_customPostList(){
$args = array(
  \'public\'   => true,
);
$post_types = get_post_types($args,\'names\'); //get names of post types
print_r($post_types);
}?>
