여기서 선택한 값을 아래 쿼리문에 있는 $area1, $area2 위치에 넣어서 사용하려고합니다

<?php

$sql .= " and mb_id in ( select mb_id from {$g5['member_area_table']} where 1=1 and ( ( mb_area1 = '$area1' and ifnull(mb_area2,'') = '' ) or ( mb_area1 = '$area1' and mb_area2 = '$area2'))) ";

?>

아래는 자바스크립 코드입니다

function doChangeSelect(gubun) {

         if (gubun == "3") {

            $("#selectGubun1").removeClass("on");

            $("#selectGubun2").removeClass("on");

            $("#selectGubun3").removeClass("on");

            $("#selectGubun3").addClass("on");

            $("#proposeList").hide();

            $("#detailTitle").hide();

            $("#subDetail").hide();

            $("#subList").hide();

            $("#partnerNote").hide();

            $("#divRreview").hide();

            $("#selectList").hide();

            $("#searchList").show();

        }
