Question

我有4张桌子，配件中包含配件：

Accessories
id  name         price
1   accessory1      43
2   accessory2      31
3   accessory3      13
4   accessory4       9

AccessoriesKit (table store relation between Accessories and KitMain)
id  id_accessories  id_accessories_kit_main
1                1                        1
2                2                        1
3                3                        2
4                4                        2

AccessoriesKitMain
id   name
1    kit1
2    kit2

AccessoriesKitMainRelatedToProduct (table store relation between Product with their all accessories kits)
id   id_accessories_kit_main   id_product
1                          1            2
2                          2            1

我的问题是什么-我通过产品ID获得了与产品相关的配件套件，我需要对包含在主套件中的每个配件的价格求和并在视图上显示出来。

这是我获取配件的方式-

        $accessories = AccessoriesKitMainRelatedToProduct ::where('id_product', '=', $products[0]['id'])
        ->with('accessorieskitmain', 'accessorieskitmain.accessorieskit', 'accessorieskitmain.accessorieskit.accessories')->get()->toArray();

如何汇总价格并将其分组到相关工具包中？

我获取数组-控制器中$ accessories的附件配件，并将其传递到我的模板中，在foreach中将其循环：

        @foreach($accessories as $accessory)
            @foreach($accessory['accessories_kit_main'] as $kitMain)
                <div class="accessory-title">
                    <h2>{{$kitMain['name']}}</h2>
                </div>
                @foreach($kitMain['accessories_kit'] as $kit)
                    @foreach($kit['accessories'] as $singleAccessories)
                        <div>
                            <h2> {{$singleAccessories['name']}}</h2>
                            <h2> {{$singleAccessories['price']}}</h2>
                        </div>    
                    @endforeach
                @endforeach

             !! AND HERE I NEED TO PUT SUMMED UP PRICES !!

             @endforeach
         @endforeach

Answer 1

$accessories = AccessoriesKitMainRelatedToProduct::where('id_product', '=', $products[0]['id'])
    ->with(['accessorieskitmain', 
            'accessorieskitmain.accessorieskit', 
            'accessorieskitmain.accessorieskit.accessories' => function($query){
                $query->sum('price');
    }])
    ->get()->toArray();

希望它对您有用！

Sum记录嵌套关系中的值
