重用 PHPMailer 发送第二封电子邮件？

Question

我正在开发一个订购系统，需要向客户、经销商和网站所有者发送一封电子邮件。

所有者和经销商可以收到相同的电子邮件（订单详细信息等），但客户需要一封内容略有不同的电子邮件来包含感谢信息。

目前我有这个：

require_once('PHPMailer/class.phpmailer.php');
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 0; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "";
$mail->Port = 587; // or 587
//$mail->IsHTML(true);
$mail->Username = "";
$mail->Password = "";
$mail->SetFrom("");
$mail->IsHTML(true);
$mail->Subject = "Online Shop - New Order - " . $orderNumber;
$mail->Body = "A new order has been placed with Online Shop. Please find the delivery details below: <br><br> " . $orderDetails;
$mail->AddAddress($distributerEmail); //Distributor email address
$mail->AddAddress($ownerEmail); //Owner email address
if($mail->Send()){  }else{ $error = "Error sending message! <br/>"; }

如何重用 $mail 组件来发送另一封电子邮件，而无需定义服务器详细信息？我

Answer 1

试试这个：

require_once 'PHPMailerAutoload.php';
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 0; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "";
$mail->Port = 587; // or 587
//$mail->IsHTML(true);
$mail->Username = "";
$mail->Password = "";
$mail->SetFrom("");
$mail->IsHTML(true);
$mail->Subject = "Online Shop - New Order - " . $orderNumber;
$mail->Body = "A new order has been placed with Online Shop. Please find the delivery details below: <br><br> " . $orderDetails;
$mail->AddAddress($distributerEmail); //Distributor email address
$mail->AddAddress($ownerEmail); //Owner email address
if($mail->Send()){  }else{ $error = "Error sending message! <br/>"; }

// We delete the addresses of distributer and owner.
$mail->ClearAddresses();

$mail->AddAddress($customerEmail);
$mail->Body = "new body";

if($mail->Send()){  }else{ $error = "Error sending message! <br/>"; }

将 Mailer 创建提取到一个函数中，它看起来会更好

• PHP 7.2 中添加了对象返回类型声明 - 如果您处于以下位置，请删除

  :  PHPMailer

  。
• 我在这里使用 Composer：

  "phpmailer/phpmailer": "^6.9"

  依赖项位于我的

  composer.json

  中。

use PHPMailer\PHPMailer\PHPMailer;

function createMailer(): PHPMailer
{
    $mailer = new PHPMailer();

    $mailer->isSMTP();
    $mailer->Host = getenv('mail.host');
    $mailer->SMTPAuth = true;
    $mailer->Username = getenv('mail.username');
    $mailer->Password = getenv('mail.password');
    $mailer->SMTPSecure = 'tls';
    $mailer->Port = 587;
    $mailer->setFrom(getenv('mail.from.address'), getenv('mail.from.name'));
    $mailer->isHTML();
    $mailer->CharSet = PHPMailer::CHARSET_UTF8;

    return $mailer;
}

• 我正在从环境变量中读取一些值 - 不过你可以对字符串进行硬编码

使用方法

$mailer = createMailer();

// 1st mail
$mailer->clearAddresses();
$mailer->addAddress('[email protected]');
$mailer->Subject = 'Your Subject';
$mailer->Body = 'Hello name,<br><br>your order has been received.';
if ($mailer->send()) {
    echo '1st mail sent successfully.';
} else {
    echo 'Failed to send 1st mail.';
}

// 2nd mail
$mailer->clearAddresses();
$mailer->addAddress('[email protected]');
$mailer->Subject = 'Your Subject';
$mailer->Body = 'Hello name,<br><br>your order has been received.';
if ($mailer->send()) {
    echo '2nd mail sent successfully.';
} else {
    echo 'Failed to send 2nd mail.';
}

• 在发送邮件之前，我们总是先清除收件人
  • 如果您使用带有

    ->addCC

    或

    ->addBCC

    的抄送或密送字段，则必须使用

    ->ClearAllRecipients()

    而不是

    ->clearAddresses()

  • 如果您使用

    ->addAttachment()

    发送附件，则必须致电

    ->clearAttachments()

    来清除它们
