使用PHPMailer发送phpexcel文档

我试图在依赖phpexcel生成电子表格的脚本上使用phpmailer。

它完美地保存了电子表格,我没有收到phpmailer错误,但它没有发送。我不确定如果它不发送 或 显示错误。

以下是保存excel并生成邮件程序的部分:

                $writer = PHPExcel_IOFactory::createWriter($phpExcel, "Excel2007");
                $writer->save('Coaching Report - Test.xlsx');

                $mail = new PHPMailer(true);
                 //$address = "s";
                $address = "omitted";

                $date = date("D M d, Y");


                try{
                $mail->setFrom("omitted");
                $mail->addAddress($address);
                $mail->AddAttachment($writer,"Coaching Report $date.xlsx");
                $mail->isHTML(true);
                $mail->Subject    = "Weekly Coaching Report";
                $mail->Body       = "Attached is the weekly coaching report for " . $date;
                $mail->Send();
                echo 'message sent';

                } catch (Exception $e){
                    echo 'message failed';
                    echo 'mail error:' . $mail->ErrorInfo;
                }

                mysqli_close($conn);
