控制器（给前端接口）：

 /**
     * 新增&编辑店鋪
     * @param $data
     * @param $user_id
     * @return array
     */
    public function editstore(){
        $userId = input('param.user_id');
        if (empty($userId)){
            return error_code(11067);
        }
        $data['shop_name'] = input('param.shop_name');
        $data['shop_logo'] = input('param.shop_logo');
        $data['shop_introduce'] = input('param.shop_introduce');
        $data['id'] = input('param.id');
        $model = new StoreManagementModel();

        return $model->editstore($data, $userId);
    }

模型层：

     /**

            if ($this->allowField(true)->save($store_data)) {
