데이터베이스에서 파일을 편집하는 방법은 무엇입니까?

나는 데이터베이스에 생성 된 모든 사용자를 유지하는 등록 양식을 만들었습니다. 자, 각각의 생성 된 사용자 옆에 버튼 (링크, 무엇이든)을 넣으려고합니다. 버튼을 클릭하면, 새로운 로그인 폼이 나타납니다. 필요한 필드를 모두 채우고 업데이트 버튼을 누르면, 편집 된 사용자가 데이터베이스에 표시됩니다. 어떤 도움이 필요합니까? 미리 감사드립니다.데이터베이스에서 파일을 편집하는 방법은 무엇입니까?

주어진 사용자에 대한 업데이트 쿼리를 수행하기 만하면됩니다. 귀하의 질문에 대한 코드를 게시하지 않았기 때문에 귀하를 도울 수 없습니다. 또한 여기에서했던 것처럼 일반 텍스트로 암호를 저장하지 마십시오. –

이것은 내가 내 데이터베이스 코드의 2 세트에서 사용하는 코드입니다 - view.php 표시 목록의 각 레코드 옆에 편집 옵션이있는 레코드를 선택한 다음 편집을 클릭하면 edit.php가 열리고 세부 사항을 변경하고 저장할 폼이 표시됩니다. 필요한 경우 테이블 구조와 내용을 보낼 수 있습니다. 꽤 많은 코드가 있지만 나는 원하는대로 정확하게 작동하는 시스템을 전체적으로 보여주고 싶습니다. 그것은 MySQL을하지만, 나는) =
