아 update파일에는

<?
if (!defined("_GNUBOARD_")) exit; // 개별 페이지 접근 불가

// 자신만의 코드를 넣어주세요.

$wr_1 = "$ext1_00";
$sql1 = " update $write_table set wr_1 = '$wr_1' where wr_id = '$wr_id' ";
sql_query($sql1);

$wr_2 = "$ext2_00";
$sql2 = " update $write_table set wr_2 = '$wr_2' where wr_id = '$wr_id' ";
sql_query($sql2);

$wr_3 = "$ext3_00";
$sql3 = " update $write_table set wr_3 = '$wr_3' where wr_id = '$wr_id' ";
sql_query($sql3);

$wr_4 = "$ext4_00";
$sql4 = " update $write_table set wr_4 = '$wr_4' where wr_id = '$wr_id' ";

$wr_5 = "$ext5_00";

넣었습니다.
