Laravel：搜索結果搜索？page = 2不顯示任何內容，只是空白頁

Question

我的分頁工作正常，但是當使用搜索組件時，它只顯示結果的第一頁。 沒有搜索的我的頁面URL看起來像： http://localhost:8000/dictionary-management/postcode?page=2 它的工作正常。

我的第一頁與搜索的URL： http://localhost:8000/dictionary-management/postcode/search 它的工作正常。

我的第二頁帶搜索的網址： http://localhost:8000/dictionary-management/postcode/search?page=2 而且沒什麼可顯示的，只有空白頁。

這是我的控制器搜索方法：

public function search(Request $request) { 
    $constraints = [ 
     'postcode' => $request['postcode'], 
     'address' => $request['address'] 
    ]; 

    $postcodes = $this->doSearchingQuery($constraints); 
    return view('dictionary-mgmt/postcode/index', ['postcodes' => $postcodes, 'searchingVals' => $constraints]); 
} 

private function doSearchingQuery($constraints) { 
    $query = Postcode::query(); 
    $fields = array_keys($constraints); 
    $index = 0; 
    foreach ($constraints as $constraint) { 
     if ($constraint != null) { 
      $query = $query->where($fields[$index], 'like', '%'.$constraint.'%'); 
     } 

     $index++; 
    } 
    return $query->Paginate(5); 
} 

這是我的路線：

Route::resource('dictionary-management/postcode', 'PostCodeController'); 
Route::post('dictionary-management/postcode/search', PosstCodeController@search')->name('postcode.search'); 

這是我的索引視圖：

@extends('dictionary-mgmt.postcode.base') 
@section('action-content') 
    <!-- Main content --> 
    <section class="content"> 
     <div class="box"> 
    <div class="box-header"> 
    <div class="row"> 
     <div class="col-sm-8">

     </div> 
     <div class="col-sm-4"> 
      <a class="btn btn-primary pull-right" href="{{ route('postcode.create') }}">Dodaj nowy kod pocztowy</a> 
     </div>

    </div> 
    <!-- /.box-header -->

       @component('layouts.two-cols-search-row', ['items' => ['postcode', 'address'], 'title' => ['Kod','Adres'],

        </td> 
       </tr> 
      @endforeach 
      </tbody> 
      <tfoot> 
       <tr>

      </table> 
     </div> 
     </div>

    </div> 
    <!-- /.box-body --> 
</div> 
    </section> 
    <!-- /.content --> 
    </div> 
@endsection 

這是我的搜索組件：

<div class="row"> 
    @php 
    $index = 0; 
    @endphp 
    @foreach ($items as $item) 
    <div class="col-md-6"> 
     <div class="form-group"> 
      @php 
      $stringFormat = strtolower(str_replace(' ', '', $item)); 
      @endphp 
      <label for="input<?=$stringFormat?>" class="col-sm-3 control-label">{{$title[$index]}}</label> 
      <div class="col-sm-9"> 
      <input value="{{isset($oldVals) ? $oldVals[$index] : ''}}" type="text" class="form-control" name="<?=$stringFormat?>" id="input<?=$stringFormat?>" placeholder="{{$title[$index]}}"> 
      </div> 
     </div> 
    </div> 
    @php 
    $index++; 
    @endphp 
    @endforeach 
</div> 

請幫幫忙，我不知道哪裏是我的錯......

試試這個

{{ $postcodes->appends(request()->input())->links()}} 

，而不是{{ $postcodes->links() }}
