제출시 PHP 오류가 표시됩니다.

Question

사용자가 현재 암호를 입력했지만 올바르게 입력되었지만 더 이상 입력하지 않으면 오류 메시지가 나타나려고합니다. 그래서 예. 사용자는 자신의 비밀번호를 변경하고 현재 비밀번호를 입력하고 올바른 비밀번호를 입력하십시오. 'Please enter all fields!'라는 오류 메시지가 나타납니다. 제발 여기 http://gyazo.com/ea789cc87166cea88453d6c1c59733b6

(이 말을해야 : 지금은 그냥 아무것도 난 정말 붙어있어 :(

어떤 도움이 좋을 것

. 나는 당신의 코드를 완전히 읽지는 않았다. (나는 너무 많이 생각했다.)하지만 이제는 이것이 더 잘 작동 할 것이라고 생각한다. 귀하의 SQL 물건을 확인할 수 있지만 나머지 꽤 잘 작동합니다.

HTML 출력 전에 세션을 시작했는지 확인하십시오. 비밀번호 필드에 데이터가 포함되어 있는지 여부를 알아야합니다. 비밀번호 필드에 데이터가 포함되어 있는지 확인해야합니다. 또한 오류가 발생하지 않으면 쿼리가 예상대로 완료되는지 확인해야합니다. 오류보고 기능을 추가했는데 잘하면이 기능이 작동합니다.
