SKU 封装思路分享

[slowlyo]

这里只实现了部分功能, 仅供参考~

SKU 还是推荐自行在前端实现~

    // 组件结构封装
    public function sku($name, $label)
    {
        $key         = 'sku_' . $name;
        $changeEvent = [
            [
                'actionType'  => 'rebuild',
                'componentId' => $key,
            ],
        ];

        return amisMake()
            ->ComboControl($name, $label)
            ->multiLine()
            ->noBorder()
            ->items([
                amisMake()->ComboControl('spec_group')->multiple()->multiLine()->addButtonText('添加规格组')->items([
                    amisMake()->TextControl('spec_name', '规格名称')->required(),
                    amisMake()
                        ->ComboControl('specs', '规格值')
                        ->multiple()
                        ->draggable()
                        ->addButtonText('添加规格')
                        ->items([
                            amisMake()->TextControl('spec_value')->set('unique', true)->required(),
                        ]),
                ]),
                amisMake()->Divider()->visibleOn('${spec_group}'),
                amisMake()->VanillaAction()->label('生成Sku')->className('mb-3')->onEvent([
                    'click' => [
                        'actions' => [['actionType' => 'rebuild', 'componentId' => $key]],
                    ],
                ])->visibleOn('${spec_group}'),
                // 通过 service 在后端生成sku结构
                amisMake()->Service()->id($key . '_service')->showErrorMsg(false)->initFetchSchema(false)->schemaApi([
                    'url'    => '/goods_type_sku',
                    'method' => 'post',
                    'data'   => [
                        'spec_group' => '${spec_group}',
                    ],
                ]),
            ]);
    }

    // sku生成逻辑
    public function skuApi(Request $request)
    {
        $specGroup = $request->input('spec_group');
        $groupName = Arr::pluck($specGroup, 'spec_name');

        $spec = collect($specGroup)->pluck('specs')->map(fn($item) => array_column($item, 'spec_value'))->toArray();

        $specCrossJoin = Arr::crossJoin(...$spec);

        $groupNameMd5 = array_map(fn($item) => md5($item), $groupName);
        $value        = array_map(fn($item) => array_combine($groupNameMd5, $item), $specCrossJoin);
        $columns      = array_map(fn($item) => amisMake()->TableColumn(md5($item), $item), $groupName);

        $columns[] = amisMake()->NumberControl('price', '价格')->step(0.01)->required();
        $columns[] = amisMake()->NumberControl('stock', '库存')->step(1)->required();

        $schema = amisMake()
            ->TableControl('sku_' . uniqid())
            ->needConfirm()
            ->className('pt-3')
            ->columns($columns)
            ->value($value);

        return $this->response()->success($schema);
    }
