您可以将此代码复制到插件中，激活后会将所有评论转换为帖子，并删除评论（这样您就不会有重复的评论）

您还可以使用get\\u comments（http://codex.wordpress.org/Function_Reference/get_comments )

    register_activation_hook( __FILE__, \'wpse_29474_convert_to_posts\' );
    function wpse_29474_convert_to_posts(){
        $comments = get_comments();

        foreach($comments as $comment) 
        {

            $post=get_post($comment->comment_post_ID);
            $title=sprintf("Comment on %s by %s",$post->post_title,$comment->comment_author);
            $content=$comment->comment_content;
            $my_post = array(
                 \'post_title\' => $title,
                 \'post_content\' => $content,
                 \'post_status\' => \'publish\',
                 \'post_author\' => 1
            );      
           wp_insert_post( $my_post );
           wp_delete_comment( $comment->comment_ID );
        }

    }
