PHPCMS V9에는 보조 탐색 기능이 추가되었습니다.-php手册-php.cn

오늘 phpcms를 보다가 보조 네비게이션 작성 시 문제점을 발견했습니다. 네비게이션 바 정보를 쿼리할 때 반환된 $r[arrchildid]가 제가 상상한 것과 일치하지 않습니다. 돌아왔지만 좀 달랐다.

시작 아이디어:

일반 아이디어: 문서 아래에 하위 열 ID가 있는지 확인하고, 있으면 보조 탐색을 출력합니다. 코드의 5번째 줄은 해당 열 아래에 하위 열 ID가 있는지 확인하는 것인데, 하위 열이 없으면 현재 열의 ID가 반환되므로 판단이 불가능하다는 것을 발견했습니다. 기대되는 효과가 있어서 생각을 바꿨습니다. 코드는 다음과 같습니다.
