只有在向xml文件添加了打印功能后，PHPMailer才会发送重复的电子邮件

我有一个HTML表单，它提交给一个PHP文件来处理并通过PHP邮件发送电子邮件。

我已经搜索并可能花了一天多的时间阅读可能的解决方案(尝试singleto，启动新的邮件程序，清除收件人，检查是否有可能导致双重提交的不适当插件[如firefox的yslow]确保没有发生双重提交，在PHPmailer和其他一些程序中将格式更改为UTF-8。(

在所有这些之后，我把我的代码分解成几块，并一点一点地测试它，发现当我说要制作XML文件时，PHP邮递员决定重新发送电子邮件。(在一秒钟或更短的时间内(。

任何帮助都将不胜感激！！

这是我的代码(在XML之前(，只需将其转换为您的gmail密码：

  <?php
    require 'PHPMailer-master/PHPMailerAutoload.php';
    if(isset($_POST['contract_number'])) {
        // Who to send email to and subject
         function clean_string($string) {
          $bad = array("content-type","bcc:","to:","cc:","href");
          return str_replace($bad,"",$string);
        }
         // TEST EMAIL FIELDS //
         $base_recipients = array('test@gmail.com');
         $pre_30_cancel_recipients = array('test1@gmail.com');
         $not_aa1014_recipients = array('test2@gmail.com');
         $aa1014_recipients = array('test3@gmail.com');
         // TEST EMAIL FIELDS //

         // $base_recipients = array('test5@gmail.com', 'test6@gmail.com', 'test7@gmail.com');
         // $pre_30_cancel_recipients = array('test8@gmail.com');
         // $not_aa1014_recipients = array('test9@gmail.com');
         // $aa1014_recipients = array('test10@gmail.com');

        $agent = $_POST['agent']; 
        $contract_number = $_POST['contract_number'];

Email sent! 

通过在最后一个大括号之前添加以下内容，邮递员将发送2封电子邮件(为了测试起见，请确保您始终选择"Corp"作为附属公司，因为如果您选择另一个，则它应该发送两封电子邮件。(：

if ($mailer->send()) {
$str = '<?xml version="1.0" encoding="UTF-8"?><entrys></entrys>';

$xml = simplexml_load_string($str);
$whensent = date("Y-m-d H:i:s");
$whoto = $final_recipients;
$subject = $email_subject;
$xml->reports = "";
$xml->reports->addChild('whensent', $whensent);
$xml->reports->addChild('whoto', $whoto);
$xml->reports->addChild('subject', $subject);
$xml->reports->addChild('emailmessage', $email_message);
