Php 数据库事务Laravel未回滚

如果满足某个条件，我将尝试使用Laravel DB facade回滚数据库事务。但是我的回滚不起作用

首先，我用

DB:：beginTransaction（）启动了我的DB事务

其次，我编写了查询以创建以下内容：

创建新的付款批次
创建付款批记录
创建付款审批
创建付款审批人
第三，我然后做了一些条件，以知道何时回滚或提交我的DB事务。但是，回滚不起作用。示例我的代码中满足了此条件块，但从未回滚

if(!$mail_status){
   DB::rollBack();
    return back()->with('error', 'Mail not send to approvers. Try again or contact system administrator.');
}

下面是完整的代码块

//Start transaction
    DB::beginTransaction();

    try{

        //Run Queries

        //Create a new payment batch
        $batch = Batch::create([
            'uuid' => uniqid(),
            'batch_name' => $batch_config->batch_name,
            'service_code' => Auth::user()->service_code,
            'created_by' => Auth::user()->name,
        ]);

        //Create parameters for new payment batch record
        foreach($batch_record_config as $data){
            $record[] = [
                'batch_id' => $batch->batch_id,
                'payee_name' => $data['payee_name'],
                'bank_id' => $data['bank_id'],
                'bank_name' => $data['bank_name'],
                'account_type' => $data['account_type'],
                'account_number' => $data['account_number'],
                'amount' => $data['amount'],
                'description' => $data['description'],
                'year' => date("Y"),
                'month' => date("F", mktime(0, 0, 0, date("n"), 10)),
                'uuid' => uniqid(),
                'service_code' => Auth::user()->service_code,
                'created_at' => now(),
                'created_by' => Auth::user()->name,
            ];
        }
        $batch_record_status = DB::table('batch_record')->insert($record);

        //Generate new payment approval
        $payment_approval = PaymentApproval::create([
            'uuid' => uniqid(),
            'batch_id' => $batch->batch_id,
            'service_code' => Auth::user()->service_code,
            'created_by' => Auth::user()->name,
            'deleted' => 0,
        ]);

        //Generate payment approvers for the payment approval
        $payment_approvers = [];
        foreach($approval_users as $data){
            $payment_approvers[] = [
                'uuid' => uniqid(),
                'payment_approval_id' => $payment_approval->id,
                'approval_user_id' => $data->id,
                'approval_level_id' => $data->approval_level_id,
                'batch_id' => $batch->batch_id,
                'approval_position_value' => $data->approval_level->approval_position,
                'approval_level_name' => $data->approval_level->approval_level,
                'user_id' => $data->user_id,
                'batch_name' => $batch->batch_name,
                'service_code' => Auth::user()->service_code,
                'approved' => 0,
                'deleted' => 0,
                'created_at' => now(),
                'created_by' => Auth::user()->name,
            ];
        }
        $payment_approvers_status = DB::table('payment_approvers')->insert($payment_approvers); 


        // If DB transcation is successful.
        if($batch && $batch_record_status && $payment_approval && $payment_approvers_status){

            //get the next approvers
            $next_approvers = $this->next_approvals($payment_approval->id);

            if($next_approvers){
                //send mail to the next approvers
                $mail_status = $this->send_approvers_mail($next_approvers,$batch);
                if(!$mail_status){
                    DB::rollBack();
                    return back()->with('error', 'Mail not send to approvers. Try again or contact system administrator.');

                }else{
                    DB::commit();
                    return back()->with('success', 'Batch has being initialized');
                }
            }else{
                DB::rollBack();
                return back()->with('error', 'Approvers not found. Try again or contact system administrator.');
            }  

        }else{
            DB::rollBack();
            return back()->with('error', 'Something went wrong. Try again.');
        }



    }catch(\Exception $e){
        DB::rollBack();
        dd($e);
        return back()->with('error', 'Something went wrong... Contact system administrator. Thanks.');
    }

您没有提到DB get commit或抛出一些错误？请检查邮件函数响应中的内容。我认为您在邮件中获得了成功，因为您的else条件是不执行任何案例。
我查看了您的，正如其他人正确指出的，您需要提交事务。我在你的代码里看不到。据我所知，基本上有两种使用事务的方法。
1. 

二,

如果您使用的是第二种方法，则不必进行任何提交，失败时将自动回滚

我想这是你这一行的错误
$next\u approvers=$this->next\u approvals（$payment\u approval->id）；
我找不到代码中定义的*next_approvals8属性，而且您正在使用Laravel ORM和Raw语句（PaymentApproval:：create&DB:：table（'batch_record'）->insert（$record）；）

尝试坚持使用1，看看是否有效。
您需要提交
DB:：commit（）并使用
DB:：beginTransaction（）在try部分中有一个DB:：commit（）；在检查邮件是否成功的条件内。我还尝试包括DB:：BeginTransaction（）；在try-catch内，但也不起作用。
DB:：beginTransaction
调用不需要在try/catch块内，不用担心。哪个回滚不工作？所有回滚都不工作。如果邮件不成功，我更感兴趣。
\DB::beginTransaction();
    try {
        DB::table('users')->update(['votes' => 1]);
        DB::table('posts')->delete();
    } catch (\Exception $e) {
        $count = 0;
        \DB::rollBack();
        \Log::info(self::LOG_PREFIX . 'Some Msg ', [$e->__toString()]);
    }

    \DB::commit();

DB::transaction(function () {
        DB::table('users')->update(['votes' => 1]);
        DB::table('posts')->delete();
    });
