选中复选框并选择使用过滤器后选择的选项

Question

使用过滤器相应地显示产品。 我正确地得到了过滤结果。但是我无法在下一个过滤器中保留过滤结果。 即使用三个过滤器。 创建于 - 日期过滤器 价格 - 过滤 卖方 - 过滤器

一切都是分开工作。

但是我无法在下一个过滤结果中做到这一点。另外，我无法检查选中的值并选择要选择的值。我该怎么做？我在下面给出的代码：

控制器：

          $category_id = Category::where('name', $main)->value('id');
          if($category_id == "")
          {
            $all_categories_id = Category::pluck('id');
          }
          else
          {
            $all_categories_id = Category::where('parent_id', $category_id)->pluck('id');
            $all_categories_id->push($category_id);
          }
          $product_id = Product::where('name', 'like','%'.$request->name.'%')->pluck('id');
          $id = ProductCategory::whereIn('product_id', $product_id)->whereIn('category_id', $all_categories_id)->pluck('id');
          $product_id = Product::whereIn('id', $id)->pluck('id');
          $seller = Product::whereIn('id', $id)->pluck('seller_id'); 
          $seller_name = User::whereIn('id', $seller)->get(); 

          $products = Product::where(function($query) use ($product_id){
            $min_price = Input::has('min_price') ? Input::get('min_price') : null;
            $max_price = Input::has('max_price') ? Input::get('max_price') : null;        
            $seller = Input::has('seller') ? Input::get('seller') : [];

            if(isset($min_price) && isset($max_price)){
              $query->whereBetween('price_per_unit', [$min_price, $max_price])
                        ->whereIn('id', $product_id);              
            }

            if(isset($days)){
              foreach($days as $key => $day){
                $end = Carbon::now();
                $get_required_date = Carbon::now()->subDays($day);
                $products = Product::where('created_at', '>', $get_required_date)->pluck('id');
                $query->whereIn('id', $products)->whereBetween('price_per_unit', [$min_price, $max_price]);              
              }
            }

            if(isset($seller)){              
                foreach($seller as $key => $sell){
                  $query->whereIn('id', $product_id)
                        ->where('seller_id', $sell);
               }
            }
            $query->whereIn('id', $product_id);
          })->get();
      }    



        //Categories Name in Sidebar
        $category = ProductCategory::whereIn('product_id', $id)->pluck('parent_id');
        $category_name = Category::whereIn('id', $category)->pluck('name');

        //Categories Name in dropdown
        $main_categories = Category::where('parent_id', '0')->pluck('name'); 

        //Profile Image Mapping
        $user = Auth::user();
        $directory = 'uploads/users/images/'.$user->id;
        $main_categories = Category::where('parent_id', '0')->pluck('name');
        if (is_dir($directory)) {
        $files = scandir ($directory);
        $img_file = $directory.'/'.$files[2];
        $user['front_img'] = $img_file;
        }
        $profile = $user['front_img'];

        //Product Image Mapping     
        $products->map(function ($product) {
        $directory = 'uploads/products/images/'.$product->id;
        $brand = Brand::select('name')->where('id', '=', $product->brand)->pluck('name');
        $brand_name = $brand->first(function($value, $key) {
          return $key == 'name';
        });
        if (is_dir($directory)) {
          $files = scandir ($directory);
          $img_file = $directory.'/'.$files[2];
          $product['front_img'] = $img_file;
          $product['brand'] = $brand_name;
          return $product;
        }
          return $product;
        });

      return view('pages/product', compact('main_categories','seller_name', 'profile', 'products', 'main', 'category_name'));

在这种情况下，您可以使用ajax()代替表单提交。但是，如果您不想使用ajax()并继续使用表单提交方法，那么您必须自己维护状态。要做到这一点，您必须从控制器返回检查哪些元素或在下拉列表中选择了什么值，并使其代表这些值进行检查和选择。 laravel提供了这种方法return redirect with input

您可以像以下一样使用它：

return Redirect::back()->withInput(Input::all());
