write_ok 부분에 대한 질문입니다.

저기요 ㅠㅠ 흑흑흑... 딴게시판은 올려놓는거에대해서 잘되는데 혹 저는 잘안됩니다.

파일네임은 file_name 인데요 이 이름을 카피부분에 넣으면 data 폴더에 넣도록하는 함수명령어가 무엇입니까?

저는 이렇게 해도 안넣어집니다 으악@@@@@@!!

@system("cp data/$file_name"); 이것도 해보고 흐흑흑..

if(!copy($file_name,"data/$file_name")) 해도 서버에 저장되지않습니다.

도와주세요!!! 저의 write_ok.php 소스입니다.
