phpmailer 发送到多封电子邮件，包括唯一的退订链接

Question

我正在制作 php 脚本来发送带有取消订阅每个收件人的选项的时事通讯。

下面的代码有效 - 向我在 DB 中的每个订阅者发送和发送电子邮件。但是，它会向所有人添加取消订阅链接。因此，如果我有 2 个订阅者，他们都会获得相同的消息正文和 2 个取消订阅的链接。

这里是代码。

if (isset($_POST['sendemail'])) {
    require_once "phpmailer/class.phpmailer.php";
    require_once "phpmailer/class.smtp.php";
    $message = "TEST MESSAGE";
    $mail = new PHPMailer();
    $body = eregi_replace("[\]",'',$message);
    $mail->IsSMTP();
    $mail->SMTPAuth = true;
    $mail->SMTPSecure = 'ssl';
    $mail->Host = "myserver";
    $mail->Port = 465;
    $mail->Username = "myuser";
    $mail->Password = "mypass";
    $mail->SMTPDebug = false;
    $mail->do_debug = 0;
    $mail->SetFrom("me@domain.ltd", "Me");
    $mail->AddReplyTo("me@domain.ltd", "Me");
    $mail->AddAddress("some@email.com", "member");
    // I GET LIST OF SUBSCRIBED EMAILS AND LOOP THE MAIL SENDING
    $result = dbquery("SELECT * FROM emails WHERE email_sub='1'");
    while($row = dbarray($result)) {
        // HERE SHOULD BE ONIQUE UNSUBSCRIBE LINKO FOR EACH EMAIL
        $body .= "<br /><a href=\"http://someurl.tld/emails.php?email=".$row["email_address"]."\">Unsubscribe</a>";
        $mail->Subject = $subject;
        $mail->MsgHTML($body);
        $mail->WordWrap = 50;
        $mail->AddBCC($row["email_address"], $row["email_name"]);
        $mail->addCustomHeader("List-Unsubscribe","<admin@keepity.com>, <http://keepity.com/?email=".md5(md5($row["email_address"])).">");
    }
    if(!$mail->Send()) {
        echo "<i class=\"fa fa-warning\"></i> Error: " . $mail->ErrorInfo."<br />";
    } else {
        echo "Done";
    }
}

所以电子邮件看起来像这样

Message body.....

Unsubscribe
Unsubscribe

所以如果我有 100 个订阅者，每封电子邮件中就会有 100 个链接..

Answer 1

这是您发送的两个链接：

1. InMessage 正文： 2.内页眉 , http://url_to_unscribe.com

这是一个应该如何调用的示例：

  $mail->addCustomHeader("List-Unsubscribe",'<admin@keepity.com>, <http://keepity.com/?email='.$address.'>');

Answer 2

请试试这个

$body = eregi_replace("[\]",'',$message);

这段代码应该在while循环中。 您现在要做的是将取消订阅链接附加到 $body 的当前值，在循环中每次都添加一个新的取消订阅链接。

所以循环执行的次数，除了已经存在的链接之外，它还会继续添加一个取消订阅链接。

最终代码..

if (isset($_POST['sendemail'])) {
    require_once "phpmailer/class.phpmailer.php";
    require_once "phpmailer/class.smtp.php";
    $message = "TEST MESSAGE";
    $mail = new PHPMailer();

    $mail->IsSMTP();
    $mail->SMTPAuth = true;
    $mail->SMTPSecure = 'ssl';
    $mail->Host = "myserver";
    $mail->Port = 465;
    $mail->Username = "myuser";
    $mail->Password = "mypass";
    $mail->SMTPDebug = false;
    $mail->do_debug = 0;
    $mail->SetFrom("me@domain.ltd", "Me");
    $mail->AddReplyTo("me@domain.ltd", "Me");
    $mail->AddAddress("some@email.com", "member");
    // I GET LIST OF SUBSCRIBED EMAILS AND LOOP THE MAIL SENDING
    $result = dbquery("SELECT * FROM emails WHERE email_sub='1'");
    while($row = dbarray($result)) {
        $body = eregi_replace("[\]",'',$message);
        // HERE SHOULD BE ONIQUE UNSUBSCRIBE LINKO FOR EACH EMAIL
        $body .= "<br /><a href=\"http://someurl.tld/emails.php?email=".$row["email_address"]."\">Unsubscribe</a>";
        $mail->Subject = $subject;
        $mail->MsgHTML($body);
        $mail->WordWrap = 50;
        $mail->AddBCC($row["email_address"], $row["email_name"]);
        $mail->addCustomHeader("List-Unsubscribe","<admin@keepity.com>, <http://keepity.com/?email=".md5(md5($row["email_address"])).">");
    }
    if(!$mail->Send()) {
        echo "<i class=\"fa fa-warning\"></i> Error: " . $mail->ErrorInfo."<br />";
    } else {
        echo "Done";
    }
}
