1) Để tìm kiếm được theo ý bạn tốt nhất là bạn lưu thông tin vào CSDL rồi tìm kiếm trên CSDL thôi.
2) _ Bạn làm 1 trang đăng ký, lưu thông tin vào CSDL, đặt nhóm thành viên _ Làm trang đăng nhập, check từ CSDL. _ Làm trang download (Như kiểu cánh cửa ý) nếu đã đăng nhập đúng thông tin trên CDSL thì cho vào trang tiếp, nếu không thì quay lại trang đăng nhập
