Laravel在寄存器中插入两个用户记录，如何防止这种情况？

Question

我正在创建一个应用程序，在该应用程序中，我必须在使用自定义字段注册时插入用户。如网上所见，我在Laravel RegisterController中自定义了create方法。但是，现在，只要我注册一个新用户，该应用程序就会插入两个用户记录。有人可以帮我吗？

这是我在RegisterController中创建方法的代码

protected function create(array $data)
    {
        /********************************************************************************
         * CALCULATE ALL THE NEEDED DATA FOR THE USER
         ********************************************************************************/

        // Delete the uncompleted registration
        UncompletedRegistration::deleteByEmail($data['email']);

        // Set the right values based on the filled values
        $compercentagecreative = 0.0;
        $compercentagenotcreative = 0.0;
        $creativepercent = 0.0;

        switch ($data['headjob']) {
            case 1:
                $compercentagecreative = config('constants.percentageRates.comPercentageCreative.headjob');
                $compercentagenotcreative = config('constants.percentageRates.comPercentageNotCreative.headjob');
                $creativepercent = config('constants.percentageRates.creativePercent.headjob');
                break;
            case 2:
                $compercentagecreative = config('constants.percentageRates.comPercentageCreative.notheadjob');
                $compercentagenotcreative = config('constants.percentageRates.comPercentageNotCreative.notheadjob');
                $creativepercent = config('constants.percentageRates.creativePercent.notheadjob');
                break;
            default:
                $compercentagecreative = config('constants.percentageRates.comPercentageCreative.headjob');
                $compercentagenotcreative = config('constants.percentageRates.comPercentageNotCreative.headjob');
                $creativepercent = config('constants.percentageRates.creativePercent.headjob');
                break;
        }

            $isVatValid = false;
        }
