分页追加在 laravel 中不起作用

Question

我有我的搜索结果我的视图中也有我的分页器，但是当我点击页面时它返回 404 错误。

我试过这个：

1- @include('front.partials.pagination', ['paginator' => $products])

2- {{$products->appends(Request::except(['page','_token']))->links() }}

3- {{$products->appends(request()->query())->links() }}

4- $products->appends(['brands' => $brandss]); //in contoller

所有的结果都一样404 Error

这是我的完整功能：

public function advancedsearch(Request $request) {
    // dd($request->all());
    $options = Specification::whereHas('subspecifications')->with(['subspecifications' => function($query){
        $query->status('Active');
    }])->get();

    $brandss = Input::has('brands') ? Input::get('brands') : [];
    $suboption = Input::has('suboptions') ? (int)Input::get('suboptions') : [];
    $min_price = Input::has('min_price') ? (int)Input::get('min_price') : null;
    $max_price = Input::has('max_price') ? (int)Input::get('max_price') : null;


    //codes
    if(!empty($request->input('brands')) && !empty($request->input('min_price')) && !empty($request->input('max_price'))){
      $products = Product::
      where('price', '>=', $min_price)
      ->where('price', '<=', $max_price)
      ->whereIn('brand_id', $brandss)
      ->paginate(12);
      $products->appends(['brands' => $brandss, 'suboptions' => $suboption, 'min_price' => $min_price, 'max_price' => $max_price]);
    }


    elseif(!empty($request->input('suboptions')) && !empty($request->input('min_price')) && !empty($request->input('max_price'))){
      $products = DB::table('products')
        ->join('product_subspecification', function ($join) {
          $suboption = Input::has('suboptions') ? Input::get('suboptions') : [];
              $join->on('products.id', '=', 'product_subspecification.product_id')
                   ->where('product_subspecification.subspecification_id', '=', $suboption);
          })
          ->where('products.price', '>=', $min_price)
          ->where('products.price', '<=', $max_price)
        ->paginate(12);
        $products->appends(['brands' => $brandss, 'suboptions' => $suboption, 'min_price' => $min_price, 'max_price' => $max_price]);
    }

    //
    elseif(!empty($request->input('brands')) && !empty($request->input('suboptions'))){
      $products = DB::table('products')
        ->whereIn('products.brand_id', $brandss)
        ->join('product_subspecification', function ($join) {
          $suboption = Input::has('suboptions') ? Input::get('suboptions') : [];
              $join->on('products.id', '=', 'product_subspecification.product_id')
                   ->where('product_subspecification.subspecification_id', '=', $suboption);
          })
        ->paginate(12);
        $products->appends(['brands' => $brandss, 'suboptions' => $suboption]);
    }

    elseif(!empty($request->input('brands')) && !empty($request->input('suboptions')) && !empty($request->input('min_price')) && !empty($request->input('max_price'))){
      $products = DB::table('products')
        ->join('product_subspecification', function ($join) {

              $join->on('products.id', '=', 'product_subspecification.product_id')
                   ->where('product_subspecification.subspecification_id', '=', $suboption);
          })
          ->where('products.price', '>=', $min_price)
          ->where('products.price', '<=', $max_price)
          ->whereIn('products.brand_id', $brandss)
        ->paginate(12);
        $products->appends(['brands' => $brandss, 'suboptions' => $suboption, 'min_price' => $min_price, 'max_price' => $max_price]);
    }
    //


    elseif(!empty($request->input('suboptions'))){
        $products = DB::table('products')
        ->join('product_subspecification', function ($join) {
          $suboption = Input::has('suboptions') ? Input::get('suboptions') : [];
              $join->on('products.id', '=', 'product_subspecification.product_id')
                   ->where('product_subspecification.subspecification_id', '=', $suboption);
          })
        ->paginate(12);
        $products->appends(['suboptions' => $suboptions]);
    }

    elseif(!empty($request->input('brands'))){
      $products = DB::table('products')
      ->whereIn('products.brand_id', $brandss)
      ->paginate(12);
      $products->appends(['brands' => $brandss]);
    }

    elseif($request->has('min_price') && $request->has('max_price')){
      $products = DB::table('products')
      ->whereBetween('price', [$min_price, $max_price])
      ->paginate(12);
      $products->appends(['min_price' => $min_price, 'max_price' => $max_price]);
    }


    return view('front.advancesearch', compact('products', 'options'));
}

有什么想法吗？

您在第一部分使用 Eloquent，在第二部分使用查询构建器，并且 appends 是一个 eloquent 方法，您从查询构建器收到的集合与来自 eloquent Eloquent 的集合不同。它没有同样的方法……
