Laravel插入或更新数组，多行

Question

大家好，即时通讯卡住了多行插入或更新更新，但如何在更新内部插入新行

只是在edit.blade.php->如果行存在更新或只是创建一个新的

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，我对您的代码做了一些编辑：

  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。 祝您有个美好的一天，并祝您应用顺利。
