您可以替换publish{post}，其中{post}是任何wordpress帖子类型。

function post_published_notification( $ID, $post ) {
    $author = $post->post_author; /* Post author ID. */
    $name = get_the_author_meta( \'display_name\', $author );
    $email = get_the_author_meta( \'user_email\', $author );
    $title = $post->post_title;
    $permalink = get_permalink( $ID );
    $edit = get_edit_post_link( $ID, \'\' );
    $to[] = sprintf( \'%s <%s>\', $name, $email );
    $subject = sprintf( \'Published: %s\', $title );
    $message = sprintf (\'Congratulations, %s! Your article “%s” has been published.\' . "\\n\\n", $name, $title );
    $message .= sprintf( \'View: %s\', $permalink );
    $headers[] = \'\';
    wp_mail( $to, $subject, $message, $headers );
}
add_action( \'publish_post\', \'post_published_notification\', 10, 2 );
