如何使用 phpmailer 向收件人发送具有唯一 ID 的退订 link

Question

我正在使用 phpmailer 向一些订阅者发送时事通讯。每个订阅者都是 "Category" 的一部分。在发送之前，我首先选择订阅者所属的类别。每个用户都有一个名为 $recipients_id 的唯一 ID。发生了什么：在下面的代码中，每个用户都获得了所有 "unscribe links";其他成员也是如此。 he/she 应该只接收退订 his/her 自己的 id:

// part of the script
$mail->IsHTML(true);                            //Sets message type to HTML             
$mail->Subject = "Newsletter";                  //Sets the Subject of the message
$mail->Body = $_POST["message"];
foreach($category_matches as $file) { // grab subscribers of the category
    // get data out of txt file     
    $lines = file($file, FILE_IGNORE_NEW_LINES); // set lines from matched file into an array
    $recipients_id = $lines[0]; //  id of recipients
    $recipients_name = $lines[2]; //  name of recipients
    $recipients_email = $lines[3]; //  email of the recipients                                  
    $mail->AddBCC($recipients_email, $recipients_name); //bcc to all subscribers of the category
    $mail->Body .= '<a href="http://example.com/newsletter/unsubscribe.php?id='.$recipients_id.'">Unsubscribe</a>'; //unsubscribe anchor    

    echo $recipients_id.'<br />'; // this echos me the id's of the subscribers in the category to check only 


}

if($mail->Send())           //Send an Email. Return true on success or false on error
{
    $result = '<div class="alert alert-success">Newsletter sent to subscribers of:<b> '.$recipients_category.'</b></div>';
}
else
{
    $result = 'div class="alert alert-danger">There is an Error</div>';
}

根据上面的评论，你的代码应该是这样的：

// part of the script
$mail->IsHTML(true);                            //Sets message type to HTML             
$mail->Subject = "Newsletter";                  //Sets the Subject of the message
foreach($category_matches as $file) { // grab subscribers of the category
    // get data out of txt file     
    $lines = file($file, FILE_IGNORE_NEW_LINES); // set lines from matched file into an array
    $recipients_id = $lines[0]; //  name of recipients
    $recipients_name = $lines[2]; //  name of recipients
    $recipients_email = $lines[3]; //  email of the recipients                              
    $mail->AddAddress($recipients_email, $recipients_name);     //Adds a "To" address

    try {
        $mail->Body = $_POST["message"].'<br /><br />'.'<a href="http://example.com/newsletter/unsubscribe.php?id='.$recipients_id.'">Unsubscribe</a>'; //unsubscribe anchor
        $mail->Send();  
        $result = '<div class="alert alert-success">Newsletter sent to subscribers of:<b> '.$recipients_category.'</b></div>';                  

    } catch (Exception $e) {
        $result = '<div class="alert alert-success">Mailer Error (' . htmlspecialchars($recipients_email) . ') ' . $mail->ErrorInfo . '</div>';
        $mail->smtp->reset(); // reset SMTP connection
    }

    $mail->clearAddresses(); // Clear all addresses for the next iteration

}

注意：只有 1 个 $mail->Body，其中包括消息和用于退订的 unique_id link。将 echo 绑定到 var $result 并在循环外 echo $result ；否则，对于您发送的每个收件人，您将多次收到它们
