데이터를 데이터베이스에 저장하지 않겠습니까

Question

안녕하세요, 내 테스트 웹 사이트에서 데이터베이스의 데이터를 저장하지 않으므로 등록 할 때 데이터베이스에 저장하지 않으므로 로그인 할 수 없습니다. 누군가 코드에 무엇이 잘못되었는지 설명하고 그것을 고칠 수있는 방법을 말해 주시겠습니까? 을 heres 코드

당신은 당신이 달성하려고하는 것, 이것이 완벽한 해답이 될 수 없습니다 더 자세히 설명해야

/솔루션/코드이지만, 더 깨끗한 솔루션이며 PDO의 bindParam을 사용하여 SQL 삽입과 PHP의 crypt()를 피한다. mdf5보다 우수 See the post in thecodinglove
