我想在嵌套数组中添加新数据

我的文件是:

{
  "username": "erkin",
  "email": "erkin-07@hotmail.com",
  "password": "b",
  "playlists": [
    {
      "_id": 58,
      "name": "asdsa",
      "date": "09-01-15",
      "musics": [
        {
          "name": "INNA - Cola Song (feat. J Balvin)",
          "duration": "3.00"
        },
        {
          "name": "blabla",
          "duration": "3.00"
        }
      ]
    }
  ]
}

我想在此播放列表部分添加音乐:

{
  "username": "erkin",
  "email": "erkin-07@hotmail.com",
  "password": "b",
  "playlists": [
    {
      "_id": 58,
      "name": "asdsa",
      "date": "09-01-15",
      "musics": [
        {
          "name": "INNA - Cola Song (feat. J Balvin)",
          "duration": "3.00"
        },
        {
          "name": "blabla",
          "duration": "3.00"
        },
        { …

我的路线在这里

Route::get('sign-up', ['as' => 'signUp', 'uses' => 'UserController@signUpGet']);
Route::post('sign-up', ['as' => 'signUpPost', 'uses' => 'UserController@signUpPost']);

调节器

return redirect('signUp')->withInput();

和观点

    <form role="form" method="POST" action="{{route('signUpPost')}}"> 
        <input type="text" class="form-control" name="username" value="{{ old('username') }}">
</form>

{{old()}}函数返回空值. 我
