============  댓글 역순으로 하는 방법  ============

1.  modules/comment/comment.model.php 에서

function getCommentList($document_srl, $page = 0, $is_admin = false, $count = 0) {    함수 내부에서

if(!$page) $page = (int)( ($oDocument->getCommentCount()-1) / $comment_count) + 1;               

// 정해진 수에 따라 목록을 구해옴
$args->document_srl = $document_srl;
$args->list_count = $comment_count;
$args->page = $page;
$args->page_count = 10;

$output = executeQueryArray('comment.getCommentPageList', $args);

부분을 찾아서...    아래처럼 수정할것  (빨간색 부분에, 댓글 역순으로 출력할 게시판 mid 값으로 바꿔주세요)

// 정해진 수에 따라 목록을 구해옴
$args->document_srl = $document_srl;
$args->list_count = $comment_count;
$args->page = $page;
$args->page_count = 10;

// 페이지 역순 기능 위해서 수정 (sejin7940)
if(Context::get('mid')=="board_chat") {   
 $page=1;
 $output = executeQueryArray('comment.getCommentPageListReverse', $args);
}
else {
 if(!$page) $page = (int)( ($oDocument->getCommentCount()-1) / $comment_count) + 1;               
 $output = executeQueryArray('comment.getCommentPageList', $args);
}

2. modules/comment/queries/getCommentPageListReverse.xml  파일을 추가할 것

<query id="getCommentPageListReverse" action="select">
    <tables>
        <table name="comments" alias="comments" />
        <table name="comments_list" alias="comments_list" />
    </tables>
    <columns>
        <column name="comments.*" />
        <column name="comments_list.depth" alias="depth" />
    </columns>
    <conditions>
        <condition operation="equal" column="comments_list.document_srl" var="document_srl" notnull="notnull" pipe="and" />
        <condition operation="equal" column="comments_list.comment_srl" var="comments.comment_srl" filter="number" pipe="and" />
        <condition operation="more" column="comments_list.head" default="0" pipe="and" />
        <condition operation="more" column="comments_list.arrange" default="0" pipe="and" />
    </conditions>
    <navigation>
        <list_count var="list_count" default="list_count" />
        <page_count var="page_count" default="10" />
        <page var="page" default="1" />
  <index var="sort_index" default="head" order="desc" />
  <index var="sort_index" default="comments_list.depth" order="asc" />
    </navigation>
</query>
