이 문제는 당분간 당황 스럽습니다. 기본적으로 나는 제출할 때 동시에 여러 이미지를 서버에 업로드하고 각 이미지의 레코드를 MySQL 데이터베이스에 삽입하는 양식을 가지고 있습니다.PHP - 일부 이미지가 업로드되지 않습니다.
현재 최대 6 개의 이미지를 선택하여 서버에 업로드하고 레코드를 mysql 데이터베이스에 삽입 할 수 있습니다.
이미지를 7 개만 선택하면 6 개가 업로드됩니다. 8, 9 또는 10 이미지를 선택하면 동일합니다. 항상 업로드 한 총 수보다 적은 수입니다.
11 개의 이미지를 선택하고 양식을 제출해도 아무런 문제가 없으며 이미지가 업로드되지 않고 이미지 기록도 데이터베이스에 삽입되지 않습니다.
내가 이미지를 확인하고 모두가 허용 된 파일 형식, 크기, 치수 등 내 내가 왜 모든 업로드 않습니다 max_file_uploads 그래서 200에 설정 한 사용하고 웹 서버에 대한 php.ini 파일하지만 하나의 인스턴스와 다른 인스턴스에서 내 이미지 중 하나는 어떤 것도 업로드하지 않습니까?
코드가 길어서 해당 항목 만 포함시켜 보겠습니다.

미안 해요, 난에만 적용 할 수있는 물건을 포함, 알려 시도 어떤 것. 감사합니다.
