WordPress：为什么帖子更新后会触发“删除帖子之前”操作？

Question

我仅在删除已发布的帖子时才尝试创建通知，但是当我更新任何已发布的帖子时会触发通知吗？

我做错了！谢谢。

function deleted_published_post_notify_author( $post ) {

    global $post;

    $send_published = get_post_meta( $post->ID, 'published_send_once', true );
    if ( ! empty( $send_published ) ) return;

    if( current_user_can('administrator')) {

        if( get_post_status($post) == 'publish' ) {

        $post = get_post($post->ID);
        $author = $post->post_author;
        $author_name = get_the_author_meta( 'display_name', $author );
        $link =  'https://www.cgartzone.com/submission-rules';
        $image = 'https://www.cgartzone.com/wp-content/themes/hitmag-child/assets/images/sad-icon-01.svg';
        $title = '<strong>'.$author_name.'</strong> ' . __('We are sorry to inform you that your artwork has been deleted. We recommended you to re-read our rules or contact us for more informations', 'dw-notifications'). ' <strong>'.$post->post_title.'</strong>';
        $notif = array('title'=>$title, 'link' => $link, 'image' => $image);

        update_post_meta( $post->ID, 'published_send_once', '1' );

        dwnotif_add_notification($author, $notif);
        }
    }
}
add_action( 'before_delete_post', 'deleted_published_post_notify_author' );

我尝试添加if ( wp_is_post_revision( $post ) ) return;，但没有任何反应，更新发布的帖子时如何避免此通知？只有在我删除帖子后，它才会触发！请帮忙。

function deleted_published_post_notify_author( $post ) {

    global $post;

    $send_published = get_post_meta( $post->ID, 'published_send_once', true );
    if ( ! empty( $send_published ) ) return;

    if( current_user_can('administrator')) {

        if( get_post_status($post) == 'publish' ) {

                    if ( wp_is_post_revision( $post ) )
                       return;

        $post = get_post($post->ID);
        $author = $post->post_author;
        $author_name = get_the_author_meta( 'display_name', $author );
        $link =  'https://www.cgartzone.com/submission-rules';
        $image = 'https://www.cgartzone.com/wp-content/themes/hitmag-child/assets/images/sad-icon-01.svg';
        $title = '<strong>'.$author_name.'</strong> ' . __('We are sorry to inform you that your artwork has been deleted. We recommended you to re-read our rules or contact us for more informations', 'dw-notifications'). ' <strong>'.$post->post_title.'</strong>';
        $notif = array('title'=>$title, 'link' => $link, 'image' => $image);
        update_post_meta( $post->ID, 'published_send_once', '1' );
        dwnotif_add_notification($author, $notif);
        }
    }
}
add_action( 'before_delete_post', 'deleted_published_post_notify_author' );
