디버깅을 돌려보니 네임값을 다 못받아오는 거 같기도 하고 DB에 제대로 게시글 등록이 안돼서 질문드립니다.

//게시글 작성하기
    Route::post('/list/create/contents', 'Board\BoardController@createContents')->name('board.create.contents');

            <form action="{{route('board.create.contents')}}" method="post" class="contentsForm">

    }

어떻게 등록해야되는지를 모르겠네요;; 라우트에서 createContents를 실행못하는거 같기도 하구요
