분류가 많아 추가/삭제시 특히 추가시 헷갈리는등 어려움이 많아
검색기능 활용하여 셀렉트 박스로 분류별로 표시되게 만들어 보았습니다.



아래 내용을 adm/shop_admin/categorylist.php

에

<div class="local_ov01 local_ov">

저 같은 경우 카테고리ID를 별도로 만들어 중복검색이 안되었는데
만일 다른 카테고리와 중복 출력되는경우

adm/shop_admin/categorylist.php 내용 중 아래 항목에서 (상단에 있음)

if ($stx != "") { 
    if ($sfl != "") { 
        $sql_search .= " $where $sfl like '%$stx%' "; 
        $where = " and "; 
    } 
    if ($save_stx != $stx) 
        $page = 1; 
} 

$sql_search .= " $where $sfl like '%$stx%' "; 이 부분에 앞뒤 %를 제거해 주세요 
$sql_search .= " $where $sfl like '$stx' "; 와 같이 해주시면 중복출력이 안됩니다.
