一，創建一個order類，在其中應用事務 1，創建order的model ~~~ liuhongdi@lhdpc:/data/php/admapi$ php think make:model Order Model:app\model\Order created successfully. ~~~ 2,代碼: model/Order.php [](javascript:void(0); "復制代碼") ~~~ <?php declare (strict_types = 1); namespace app\model; use think\Exception; use think\facade\Db; use think\Model; /** * @mixin \think\Model */ class Order extends Model { //類名與表名不一致時在這里指定數據表名 protected $table = "orderInfo"; public function addOrderAndGoods($orderRow,$goodsRows) { //啟動事務 Db::startTrans(); try { $result = Db::table("orderInfo")->insert($orderRow); if(!$result){ throw new Exception("insert order失敗"); } //得到orderid $orderId = Db::table('orderInfo')->getLastInsID();; //$z = 0; //$a = 100 / $z; foreach ($goodsRows as $k => $row){ $row['orderId'] = $orderId; $result = Db::table("orderGoods")->insert($row); if(!$result){ throw new Exception("insert goods失敗"); } } // 提交事務 Db::commit(); //} catch (Exception $e){ } catch (\Throwable $e){ // 事務回滾 Db::rollback(); return false; } return true; } } ~~~ [](javascript:void(0); "復制代碼") 說明：劉宏締的架構森林是一個專注架構的博客，地址：[https://www.cnblogs.com/architectforest](https://www.cnblogs.com/architectforest) ? ? ? ? ?對應的源碼可以訪問這里獲取：?[https://github.com/liuhongdi/](https://github.com/liuhongdi/) 說明：作者:劉宏締 郵箱: 371125307@qq.com ## 二，controller/Order.php 1,創建controller ~~~ liuhongdi@lhdpc:/data/php/admapi$ php think make:controller Order Controller:app\controller\Order created successfully.? ~~~ 2,代碼 [](javascript:void(0); "復制代碼") ~~~ class Order extends BaseController { /* 創建訂單 */ public function addOrder() { $orderRow = [ "orderStatus"=>0, "addTime"=>date("Y-m-d H:i:s"), "price"=>"10.5", "subject"=>"訂單:".date("YmdHis")."_".rand(100,999), ]; $goodsRows = [ [ "goodsId"=>15, "goodsName"=>"洽洽瓜子新年1裝".date("YmdHis")."_".rand(100,999), ], ]; $order = new OrderModel(); $isSucc = $order->addOrderAndGoods($orderRow,$goodsRows); if ($isSucc){ return Result::Success("成功"); } else { return Result::Error(1,"報錯"); } } } ~~~ [](javascript:void(0); "復制代碼") ## 三，測試效果: 1,成功: 查看order表:  查看goods表:  訪問: ~~~ http://127.0.0.1:8000/order/addorder ~~~ 返回:  查看增加的數據:   2,失敗: 此處需要model/Order.php中的 ~~~ //$z = 0; //$a = 100 / $z; ~~~ 此兩行代碼取消注釋，生成一個除0錯: 訪問: ~~~ http://127.0.0.1:8000/order/addorder ~~~ 返回:  查看數據庫: 可以看到order表和goods中的數據都沒有增加 注意觀察，可以發現order表中的自增id會增長， 是因為在添加數據后事務中出現異常時進行了回滾 ## 四，查看php和thinkphp的版本:? php: ~~~ liuhongdi@lhdpc:/data/php/admapi$ php --version PHP 8.1.1 (cli) (built: Dec 20 2021 16:12:16) (NTS) Copyright (c) The PHP Group Zend Engine v4.1.1, Copyright (c) Zend Technologies with Zend OPcache v8.1.1, Copyright (c), by Zend Technologies? ~~~ thinkphp: ~~~ liuhongdi@lhdpc:/var/www/html$ cd /data/php/admapi/ liuhongdi@lhdpc:/data/php/admapi$ php think version v6.0.10LTS ~~~
