我的表格不会在网站上提交。它只显示mail.php上的空白页面

我做错了什么。有一个html表单，它接受三个输入：姓名、备注和电话。表单上的操作是mail.php，方法是POST

下面是mail.php中的代码。成功后，我希望它返回主页

 <?php
// multiple recipients
//$to  = 'waleed.dogar@gmail.com' . ', '; // note the comma

error_reporting(E_STRICT);
date_default_timezone_set('America/Toronto');
require_once('/phpmailer/class.phpmailer.php');
require_once('/phpmailer/class.smtp.php');
$mail = new PHPMailer();

$mail->Subject    =  'Form Submission on Website';
$name = $_REQUEST['name'] ;
$notes = $_REQUEST['notes'] ;
$phone = $_REQUEST['phone'] ;

$body = "You have received a new message from $name.\n". "Here is the phone number:\n $phone". "Here are the additional notes: \n $notes";

$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtpout.secureserver.net"; // SMTP server
$mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
                                           // 1 = errors and messages
                                           // 2 = messages only
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Host       = "smtpout.secureserver.net"; // sets the SMTP server
$mail->Port       = 80;                    // set the SMTP port for the GMAIL server
$mail->Username   = "alex@acemobiledetailing.ca"; // SMTP account username
$mail->Password   = "password";        // SMTP account password

$mail->SetFrom('example@example.ca', 'Alex Website');

$mail->AddReplyTo("example@example.ca","Alex ");                            

$mail->MsgHTML($body);
$address = "example@gmail.com";

$mail->AddAddress($address, $name);
$mail-> Send();

if(!$mail->Send()) {
  echo "Mailer Error: " . $mail->ErrorInfo;
} else {
  echo "Message sent!";
  GOTO(http://example.com/thankyou.php);
}

?>

你看过php错误日志了吗？后藤http://example.com/thankyou.php; 不起作用，我认为你应该使用头部定位：http://example.com/thankyou.php.Try 添加ini设置“显示错误”，1；在脚本的开头，或者检查虚拟主机配置中是否有诸如ErrorLog之类的条目。如果您使用apache和linux，它们可能在/var/log/apachei中。我检查了我的错误日志，邮件上出现错误500 5。php您的包含路径对于phpMailer是错误的。PHP没有看到这些文件。为它们设置正确的路径。阅读这里：所以我修复了include路径，它仍然显示一个空白页，什么也没有发生。错误500应该是什么意思？我正在linux服务器上运行nginx
