DB::beginTransaction();开启以后,每次都只能插入最开始的一条数据,其它的都被回滚了。
代码如下:

try {
     DB::beginTransaction();
     foreach ($rightOrWrongRows as $row) {
     $question = array_combine($rightOrWrongHeader, $row);
     RightOrWrong::create([
         'question' => $question['question'],
         'answer' => $question['answer'],
         'scope' => $question['scope'],
         'degree' => 1,
         'exam_id' => $this->examId,
        ]);
     }
     DB::commit();
     } catch (\Exception $exception) {
        DB::rollBack();
        Log::info($exception->getMessage());
    }

如果关闭事务,那么就可以插入多条数据

try {
     //DB::beginTransaction();
     foreach ($rightOrWrongRows as $row) {
     $question = array_combine($rightOrWrongHeader, $row);
     RightOrWrong::create([
         'question' => $question['question'],
         'answer' => $question['answer'],
         'scope' => $question['scope'],
         'degree' => 1,
         'exam_id' => $this->examId,
        ]);
     }
     //DB::commit();
     } catch (\Exception $exception) {
        //DB::rollBack();
        Log::info($exception->getMessage());
    }

请各位朋友帮解决一下,本人菜鸟。
