我在數組中有大約50個對象。laravel 5.4分頁問題爲foreach提供了無效參數（）

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

$users = json_decode($user,true);

我把->simplePaginate(15)這個正確嗎？那我可以做json_decode嗎？像我在做什麼？我沒有得到控制器的任何錯誤。

     </div> 
    @endforeach 
    </div> 

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

</div> 
</div> 
@endsection

即使我不把這個代碼{{ $users->links() }}鑑於我仍然得到同樣的錯誤。我想問題是與控制器上的分頁代碼。

編輯

我有這個小問題還是：

之前

<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>

後

<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>

這使得代碼給出了後我錯誤試圖獲得的非財產-object，這就是我使用json_decode（）和B的原因在代碼之前。我如何解決這些問題？

你不需要json編碼任何東西並直接訪問對象屬性。

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'));

查看

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

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

我加入了更多的代碼。我改變了這樣的代碼：$ user-> john-> doe for $ user ['john'] ['doe']但是它會拋出錯誤。試圖獲得非對象的屬性。這是我去json_decode的原因。我該如何解決？ –

@MurlidharFichadia如果你急於加載關係並且存在，這不應該發生。你可以運行'dd（$ users）;'在返回視圖前分享結果 – Sandeesh

我已經添加了結果。只是其中一個數組對象。如果你想讓我添加更多的對象，我會更新它 –
