wordpress转换帖子状态更改作者姓名

Question

我使用transition_post_status挂钩来更改private to publish的帖子状态。这里的问题是当管理员将帖子状态从私有更改为发布时，帖子作者会进行更改。

我制作了自定义帖子类型abc并通过前端添加了内容。我默认将状态设置为私有。因此管理员可以从私人更改为发布。因为我在functions.php中使用了钩子。

这是我用过的代码

function _transition_post_status_1($new_status, $old_status, $post) {
    global $wpdb;

    if ( $old_status == 'private' && $new_status == 'publish' ) {
        // Reset GUID if transitioning to publish and it is empty
        $post_idd =  $post->ID;
        $post_7 = get_post($post_idd);
        $post_athr = $post_7->post_author;
        $auth_maill = get_the_author_meta( 'user_email', $post_athr ); 

        if ( '' == get_the_guid($post->ID) ) {
            $wpdb->update( $wpdb->posts, array( 'guid' => get_permalink( $post->ID ) ), array( 'ID' => $post->ID ) );
            wp_mail($auth_maill,"Confirmation Email","Your Artist Campaign has been approved.");
            do_action('private_to_published', $post->ID);  // Deprecated, use private_to_publish
        }
    }

add_action( 'transition_post_status','_transition_post_status_1',5, 3);
