Laravel點擊頁面連結按某一條件排序，這個頁面的更新連結應該如何寫？

如題。。一個圖片的展示頁面，如果我想根據某一條件排序，例如根據ID倒序排序，那麼這個在blade.php的 條件更新連結應該怎樣寫？

public function index()    {        $images = Image::paginate(10);        return view('images-list',compact('images'));    }

//想根據ID倒序，（請問這樣的情況需要另外新開一個controller嗎）public function idsort()    {        $images = Image::paginate(10);        $idsort = $images->sortByDesc('id');        return view('test',compact('images','idsort'));    }

@forelse($images as $image)                                    file)}}" />                                 
{{$image->caption}}
                  
{!! substr($image->description, 0,100) !!}
                  
 id.'/edit') }}" class="btn btn-warning pull-left">Edit   {!! Form::open(['url'=>'/image/'.$image->id, 'class'=>'pull-left']) !!} {!! Form::hidden('_method', 'DELETE') !!} {!! Form::submit('Delete', ['class' => 'btn btn-danger', 'onclick'=>'return confirm(\'Are you sure?\')']) !!} {!! Form::close() !!} 
                                          @empty         
No images yet, add a new one?
      @endforelse

已經看到這個問題多次了,這不叫更新,你只需要對查詢時排序即可。

$users = User::popular()->women()->orderBy('created_at')->get();
