使用PHPMailer向收件人发送个人电子邮件当我添加$mail-> SingleTo = TRUE时,我在To：字段中什么也没有收到;到我的代码.

当我删除$mail-> SingleTo = TRUE时;我在“收件人：”字段中收到的电子邮件地址是正确的.

这就是我得到的：

reply-to     xxxxxx <xxxx@xxxx.com>, No Reply <no-reply@no-reply.com>
to    
date         Mon, Mar 21, 2011 at 5:07 PM  
subject      Testing    
mailed-by    gmail.com 
signed-by    gmail.com

(其中xxxxxxx代表我的电子邮件地址.)

这是我的代码：

if(isset($_POST['submit']))
{
    require_once('PHPMailer_v5.1/class.phpmailer.php');


$mail         = new PHPMailer();

$subject = $_POST['subject'];
$body    = $_POST['emailbody'];
$to         = $_POST['to'];



$mail->IsSMTP(); // telling the class to use SMTP
//$mail->Host       = "localhost"; // 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->SMTPSecure = "SSL";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the GMAIL server
$mail->Username   = "xxxxxxxxxx@gmail.com";  // GMAIL username
$mail->Password   = "*********";            // GMAIL password

$mail->SetFrom('xxx@xxx.com', 'XXXXXX');

$mail->AddReplyTo("no-reply@xxxxx.com","No Reply");

$mail->Subject    = $subject;

// After adding this line I'm getting an empty To: field 
$mail->SingleTo   = TRUE;

$mail->AddAddress("address1@xxxxxx.com", 'xyz abc');
$mail->AddAddress("address2@xxxxxx.com", 'abc xyz');
//$mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test

$mail->MsgHTML($body);


if(!$mail->Send()) {
  $message= "Mailer Error: " . $mail->ErrorInfo;
}
else
{
  $message= "Message sent!";
}       
}

解决方法:

您正在使用SMTP发送电子邮件.使用Smtp发送时,phpmailer类没有使用SingleTo参数.

更多,如果你在SingleTo == true时看到CreateHeader函数,那么配方只能用于$this-> SingleToArray而不是标题本身,所以基本上它就是PHPmailer的bug.

看起来唯一的选择,除非你想修补phpmailer,就是在不使用SingleTo属性的情况下逐个发送电子邮件

解决方案将是

function & prepare_mailer($subject, $body) {

    $mail         = new PHPMailer();
    $mail->IsSMTP(); // telling the class to use SMTP
    //$mail->Host       = "localhost"; // 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->SMTPSecure = "SSL";                 // sets the prefix to the servier
    $mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
    $mail->Port       = 587;                   // set the SMTP port for the GMAIL server
    $mail->Username   = "xxxxxxxxxx@gmail.com";  // GMAIL username
    $mail->Password   = "*********";            // GMAIL password
    $mail->SetFrom('xxx@xxx.com', 'XXXXXX');
    $mail->AddReplyTo("no-reply@xxxxx.com","No Reply");
    $mail->Subject    = $subject;
    $mail->MsgHTML($body);
    return $mail;
}

foreach( $_POST['to'] as $to ){
    $mail = null;
    $mail = & prepare_mailer($_POST['subject'],$_POST['body']);
    $mail->AddAddress($to['address'], $to['name']);
    $mail->Send();

}
