1.sku含义
sku ：(stock keeping unit)是库存保存单位。即库存进出量的单位，可以是件，盒等为单位，在使用时候根据不同的业务状态，不同的管理模式来处理。在服装，鞋类使用最普遍
如图所示：
2.数据库设计
#规格属性表（对应上面的颜色尺码属性 例如specs_id代表颜色，name表示红色，蓝色；specs_id代表尺码，name表示40，42）
CREATE TABLE `mall_specs_value` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`specs_id` int(10) unsigned NOT NULL COMMENT '规格ID 1：颜色 2：尺码 3：材质',

3.添加商品sku操作逻辑
数据格式如图所示：
4.添加代码
//good.php
public function insertData($data)
{
$this->model->startTrans();
try{
$goodsId = $this->add($data);
if (!$goodsId){
return $goodsId;
}
//执行数据插入到sku表中
//如果是统一规格
if ($data['goods_specs_type'] ==1){
$goodsSkuData = [
"goods_id"=>$goodsId
];
}elseif ($data['goods_specs_type'] == 2){
$goodsSkuBusiObj = new GoodSku();
$data['goods_id'] = $goodsId;
try {
$res = $goodsSkuBusiObj->saveAll($data);
}catch (\Throwable $e){
dd($e->getMessage());
}
if (!empty($res))
{
//总库存
$stock = array_sum(array_column($res,"stock"));
$goodsUpdateData = [
"price"=>$res[0]['price'],
"cost_price"=>$res[0]['cost_price'],
"stock"=>$stock,
"sku_id"=>$res[0]['id']
];
//执行完毕之后，更新主要表中的数据
$goodsRes = $this->model->updateById($goodsId,$goodsUpdateData);
if(!$goodsRes)
{
throw new Exception("insertData:goods主表更新失败");
}
}else{
throw new Exception("sku表新增失败");
}
}
// 事务提交
$this->model->commit();
return true;
}catch (\Exception $e){
$this->model->rollback();
return show(0,$e->getMessage());
return false;
}
}
//goodsku.php
public function saveAll($data)
{
if (!$data['skus'])
{
return false;
}
foreach ($data['skus'] as $value)
{
$insertData[] = [
"goods_id" => $data['goods_id'],
"specs_value_ids" => $value['propvalnames']['propvalids'],
"price" => $value['propvalnames']['skuSellPrice'],
"cost_price"=> $value['propvalnames']['skuMarketPrice'],
"stock" => $value['propvalnames']['skuStock'],
];
}
try{
$result = $this->model->saveAll($insertData);
return $result->toArray();
}catch (\Exception $e){
return false;
}
return true;
}
public function add($data)
{
$data['status'] = 1;
try{
$this->model->save($data);
}catch (\Exception $e){
return 0;
}
return $this->model->id;
}
