register_form.php  에 인증 내용을 넣었습니다..

alert("인증되었습니다.");  로 인증되었음을 알려주었지만,
전 페이지로 이동되네요..

alert("인증되었습니다.", "./register_form.php");  이처럼 넣으면, 변수값이 넘어오질 않아서 에러가 납니다..

제 의도는.. 단순히 윈도우 창떠서 "인증되엇습니다" 가뜨고, 확인 누르면, 계속 진행 되는 것입니다..






얼랏은 전 페이지로 이동하게 펑션이 잡혀 있어서..
echo 로 넣으니.. 헤더에서 에러가 납니다..


인증되었습니다.
