【参考方案1】：

据我了解您的问题，如果没有提供 ID，您想创建一个新剧集。在这里，我稍微编辑了您的代码：

  if ($post->save()) 
      foreach (request()->input('id') as $key => $id) 
        $episode = \App\Episode::find($id);

        if($episode === null)  
          $episode = new \App\Episode;
        

        $episode->episode_name = $request->input('episode_name')[$key];
        $episode->episode_image = $request->input('episode_image')[$key];
        $episode->episode_downloadlink = $request->input('episode_downloadlink')[$key];
        $episode->episode_watchlink = $request->input('episode_watchlink')[$key];

        $episode->save();
   

让我知道它是否有效。祝您有美好的一天，祝您的应用好运。
