php 카 트 기능 구현(상)
1.수요 분석
우 리 는 데이터 베 이 스 를 사용자 의 브 라 우 저 에 연결 하 는 방법 을 찾 아야 한다.사용 자 는 목록 에 따라 상품 을 조회 할 수 있다. 사용 자 는 이후 의 구 매 를 위해 상품 목록 에서 상품 을 선택 할 수 있어 야 한다.우리 도 그들 이 선택 한 물건 을 기록 할 수 있어 야 한다. 사용자 가 구 매 를 완성 하면 그들의 주문 서 를 합산 하여 운송 상품 의 세부 사항 을 얻 고 지불 을 처리 해 야 한다. 관리자 가 위 에 도서 와 디 렉 터 리 를 추가 하고 편집 할 수 있 도록 관리 인터페이스 를 만 듭 니 다.
