Laravel错误中的自定义Bootstrap分页

我按照网站上的文档https://medium.com/appstract/custom-bootstrap-pagination-in-laravel-540922f71af0

但我有两个问题：这是我的代码

Route::get(‘rows’, ‘ComeController@rows’);

第一：

public function rows(Request $request)
{
$search_cons=$request->all();
$tablename=$search_cons[‘tablename’];
$search_alls = DB::table($tablename)
->where(‘product’,’=’,’5');

(1.)
    ->get();
    ?//it shows Method links does not exist

要么

(2).
    ->>paginate(9);
    //it will ocupy the $perPage=9  when I use dd($search_alls)



   $page =   $request->get(‘page’, 1);
    $perPage = 6;
    $items = collect($myItems);
    return view(‘my.view’, [ ‘items’ => $items->forPage($page, $perPage), ‘pagination’ => BootstrapComponents::pagination($items, $page, $perPage, ‘’, [‘arrows’ => true]) ]);
}

第二：

when click the page link to the page2 just like http://…/rows?page=2
it shows Undefined index: tablename

我使用 - > paginage（9）吗？但$ perpage缺少其功能

LengthAwarePaginator {#279 ▼
  #total: 13
  #lastPage: 2
  #items: Collection {#262 ▶}
  #perPage: 9
  #currentPage: 1
  #path: "http://localhost:8000/comefoshowmain"
  #query: []
  #fragment: null
  #pageName: "page"
}

如何修复？page = 2错误？

谢谢回复

我只是想使用分页，但是当我点击页面2时，我的代码显示错误

这是我的起源，认为不使用bootstrap组件

web.php

Route::get('rows','ProController@rows');

ProController：

public function rows(Request $request)
{
    $search_cons=$request->all();

$tablename=$search_cons['tablename'];

$search_alls = DB::table($tablename)
    ->where('product','=','5')
    ->paginate(9);

    return View('pro.results')
            ->with('search_alls', $search_alls)
            ->with('table',$tablename);

};

results.blade视图

<div class="container">
@foreach ($search_alls->chunk(3) as $chunks)
    <div class="row clearfix">
      @foreach($chunks as $searchall)
        <div class="col-md-4 column">
                <h3>
                    label
                </h3>
                <p>
                    something             
        </p>
        </div>
      @endforeach
    </div>
@endforeach
</div>
{!! $search_alls->links() !!}

第一页效果很好

http://localhost:8000/rows?table=A16& ...

当我点击第二页时

本地主机：8000 /行页= 2

表明

它显示未定义的索引：tablename
