您可以使用此代码在收到以下类型的邮件时自动发送电子邮件one 已发布。这是你的主题functions.php :

<?php 
    function post_published_notification( $ID, $post ) {
        $type = get_post_type($ID);
        if ($type == \'post-type-one\'){
            $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 (\'%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 );
?>

您可以阅读和代码，并根据需要修改所需的部件。如果你的问题清楚的话，我可以发布一个更准确的答案。然而，函数本身很有解释性。
