我在一个数组中有大约 50 个对象。

$user = User::with('abc','def','ghi','jkl','mno','pqr')
        ->where([['id', '<>', Auth::user()->id],['role', '<>', 2]])->simplePaginate(15);

$users = json_decode($user,true);

我有没有放置->simplePaginate(15)是否正确放置了这个？之后我可以做 json_decode 吗？像我在做什么？我在控制器中没有任何错误。

在视图中

    @section('content')
<div class="container-fluid">
<div></br></br></div>
@include('errors.list')

<div class="row">
  @foreach($users as $user)
   <a href="#" onclick=document.getElementById('{{$user->id}}').style.display='block'>
   <div class="col-md-3" style="margin-bottom:50px;">
   @if($user["search_status"] == 'matched')
         <div class="w3-card-12-disabled" style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
            @else
      <div class="w3-card-12" style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
      @endif
      <img align="center" src="{{$user->photo}}" style=" border-radius:50%; ; border-style: solid; border-color: #333; border-width: 5px; margin-left:15%;" width="150px !important" height="150px !important" />
      <h3 style="color:#000;  
    padding-top: 20px;" align="center">{{ $user->firstname}}</br>{{ $user->lastname}}</h3>

      <div style="display:flex; justify-content: center;">
      <div   class="tooltip2">
      <img  align="middle" style="" src="{{$user->natives->flag}}"/>
      <span class="tooltiptext">{{$user->natives->language}}</span>
      </div>
    </div>

    </br>
      </div>
   </div>     
   </a>    
   @endforeach



   <div class="row">
     @foreach($users as $user)
     <div id="{{$user->id}}" class="w3-modal">

                  {!! Form::open(['url' => '/users/'. $user->id.'/reportc']) !!}
                  {!! Form::hidden('_method', 'POST') !!}
                  {!! Form::hidden('friend', $user->id, null, ['class'=>'form-control']) !!}

               @foreach($seeks as $seek) 
                @if($seek->user_id === $user->id) 
                  {{ $seek->language}}, 
                @endif 
               @endforeach </h5>


            </div>
         </div>
      </div>
     @endforeach
   </div>

   {!! $users->links() !!}

</div>
</div>
@endsection

即使我不放这段代码{{ $users->links() }}放在视图中，我仍然会遇到相同的错误。我想问题出在控制器上的分页代码上。

已编辑

我还有这个小问题：

前

<h5 style="padding-top:10px;"><b>Campus:</b>  {{$user['campus']['campus_name']}}</h5>
               <h5 style="padding-top:10px;"><b>School:</b> {{ $user['schools']['schools_name']}} </h5>
               <h5 style="padding-top:10px;"><b>Year:</b> {{ $user['years']['years_name']}} </h5>
               <h5 style="padding-top:10px;"><b>Native Speaker of:</b> {{$user['natives']['language']}} </h5>
               <h5 style="padding-top:10px;"><b>Second Native Speaker of:</b> {{$user['snatives']['language']}} </h5>

               <h5 style="padding-top:10px;"><b>Seeking Speaker of:</b>
               @foreach($seeks as $seek) 
                @if($seek->user_id === $user['id']) 
                  {{ $seek->language}}, 
                @endif 
               @endforeach </h5>

后

 <h5 style="padding-top:10px;"><b>Campus:</b>  {{$user->campus->campus_name}}</h5>
               <h5 style="padding-top:10px;"><b>School:</b> {{ $user->schools->schools_name}} </h5>
               <h5 style="padding-top:10px;"><b>Year:</b> {{ $user->years->years_name}} </h5>
               <h5 style="padding-top:10px;"><b>Native Speaker of:</b> {{$user->natives->language}} </h5>
               <h5 style="padding-top:10px;"><b>Second Native Speaker of:</b> {{$user->snatives->language}} </h5>

               <h5 style="padding-top:10px;"><b>Seeking Speaker of:</b>
               @foreach($seeks as $seek) 
                @if($seek->user_id === $user->id) 
                  {{ $seek->language}}, 
                @endif 
               @endforeach </h5>

这给了 After 代码让我尝试获取非对象的属性时出错，这就是我使用 json_decode() 和 Before 代码的原因。我该如何解决这些问题？

您不需要对任何内容进行 json 编码并直接访问对象属性。

控制器

$users = User::with('abc','def','ghi','jkl','mno','pqr')
    ->where([
        ['id', '<>', auth()->id()],
        ['role', '<>', 2]
    ])->simplePaginate(15);

return view('someview', compact('users'));

看法

<div class="row">
    @foreach($users as $user)
        <a href="#" onclick="document.getElementById('{{ $user->id }}').style.display='block'">
            <div class="col-md-3" style="margin-bottom:50px;">
                @if($user->search_status == 'matched')
                    <div class="w3-card-12-disabled"
                         style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
                        @else
                            <div class="w3-card-12"
                                 style="border-radius:15px;width:225px; padding-top: 20px; background-color: #FFA534;">
                                @endif
                                <img align="center" src="{{ $user->photo }}"
                                     style=" border-radius:50%; ; border-style: solid; border-color: #333; border-width: 5px; margin-left:15%;"
                                     width="150px !important" height="150px !important"/>
                                <h3 style="color:#000;
    padding-top: 20px;" align="center">{{ $user->firstname }}<br/>{{ $user->lastname}}</h3>

                                <br/>
                            </div>
                    </div>
            </div>
        </a>
    @endforeach
</div>

{!! $users->links() !!}
