$board->currentCategory() 함수를 사용하면 될까요?

위와 같이 진행하고 있습니다.

적용이 안됩네요. 혹시 comment 플러그인의 list.php 에서 $content 를 불러오는 방법이 있을까요? 

$content->category2 를 받아올 수 있으면 손쉽게 가능할 것 같습니다!

안녕하세요~^^

KBoard 댓글 플러그인 list.php 파일에서

게시글 카테고리2를 불러오시려면

list.php 파일에

아래의 코드를 활용해보시겠어요?

<?php
$content = new KBContent();
$content->initWithUID($content_uid);
?>

실제 카테고리2는 $content->category2 코드를 활용해보세요.

고맙습니다.

감사합니다!!

바로 해결 됬습니다.
