문제점이 찍히는 부문이 여기부문들인데 $sql = " insert into $write_table
set wr_num = '$wr_num',
wr_reply = '$wr_reply',
wr_comment = 0,
ca_name = '$ca_name',
wr_option = '$html,$secret,$mail',
wr_subject = '$wr_subject',
wr_content = '$wr_content',
wr_link1 = '$wr_link1',
wr_link2 = '$wr_link2',
wr_link1_hit = 0,
wr_link2_hit = 0,
wr_hit = 0,
wr_good = 0,
wr_nogood = 0,
mb_id = '{$member['mb_id']}',
wr_password = '$wr_password',
wr_name = '$wr_name',
wr_email = '$wr_email',
wr_homepage = '$wr_homepage',
wr_datetime = '".G5_TIME_YMDHIS."',
wr_last = '".G5_TIME_YMDHIS."',
wr_ip = '{$_SERVER['REMOTE_ADDR']}',
wr_1 = '$wr_1',
wr_2 = '$wr_2',
wr_3 = '$wr_3',
wr_4 = '$wr_4',
wr_5 = '$wr_5',
wr_6 = '$wr_6',
wr_7 = '$wr_7',
wr_8 = '$wr_8',
wr_9 = '$wr_9',
wr_10 = '$wr_10' ";
sql_query($sql);

여기도 수정이 가능한것일까요?

php버전은 7버전입니다 과거에 쓰던게 5버전이라 안되는걸까요 서버작업하면서 옮겼는데 ph 쓰던게 높은 버전들도 있고 낮은버전들도 있어서요 코드로 수정해서 해결하는 방법은 없을까요? ㅜㅜ
