如何使用PHPMailer将多个文件附加到两个不同的电子邮件？

Question

我正在使用PHPMailer向两个不同的收件人发送两个不同的电子邮件。我想附加用户上传到两个电子邮件的多个文件。

现在，多文件附件适用于第一个邮件，但不适用于第二个邮件。

使用我当前的代码，文件仅附加到第一封邮件，而没有附件附加到第二封邮件：

// First e-mail to recipient 1

    $mail = new PHPMailer;

    $mail->setFrom('[e-mail]');

    $mail->addAddress('[e-mail]');

    $mail->Subject = 'Subject';

    $mail->isHTML(true);

    $mail->Body = '...';

    // Attach multiple files one by one

    for ($ct = 0; $ct < count($_FILES['userfile']['tmp_name']); $ct++) {

        $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name'][$ct]));

        $filename = $_FILES['userfile']['name'][$ct];

        if (move_uploaded_file($_FILES['userfile']['tmp_name'][$ct], $uploadfile)) {

            $mail->addAttachment($uploadfile, $filename);

        } else {

            $msg .= 'Failed to move file to ' . $uploadfile;

        }

    }

    $mail->send(); // I only wrote this once because as it turns out, it sends both of the mails

// Second e-mail to recipient 2

    $mail = new PHPMailer;

    $mail->setFrom('[e-mail]');

    $mail->addAddress('[e-mail]');

    $mail->Subject = 'Subject';

    $mail->isHTML(true);

    $mail->Body = '...';

    // Attach multiple files one by one

    for ($ct = 0; $ct < count($_FILES['userfile']['tmp_name']); $ct++) {

        $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name'][$ct]));

        $filename = $_FILES['userfile']['name'][$ct];

        if (move_uploaded_file($_FILES['userfile']['tmp_name'][$ct], $uploadfile)) {

            $mail->addAttachment($uploadfile, $filename);

        } else {

            $msg .= 'Failed to move file to ' . $uploadfile;

        }

    }

然后，我尝试不将整个功能复制到两个邮件中，而只添加

$mail->addAttachment($uploadfile, $filename); 

到第二封电子邮件。但是，这只会添加第一个给定的文件，并且复制此行会使同一文件发送两次。

有什么想法如何将多个（在我的情况下为3个）文件附加到两个不同的电子邮件中？

我解决了这样的问题：// First e-mail to recipient 1&nbsp; &nbsp; $mail = new PHPMailer;&nbsp; &nbsp; $mail->setFrom('[e-mail]');&nbsp; &nbsp; $mail->addAddress('[e-mail]');&nbsp; &nbsp; $mail->Subject = 'Subject';&nbsp; &nbsp; $mail->isHTML(true);&nbsp; &nbsp; $mail->Body = '...';&nbsp; &nbsp; // Attach multiple files one by one&nbsp; &nbsp; for ($ct = 0; $ct < count($_FILES['userfile']['tmp_name']); $ct++) {&nbsp; &nbsp; &nbsp; &nbsp; $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name'][$ct]));&nbsp; &nbsp; &nbsp; &nbsp; $filename = $_FILES['userfile']['name'][$ct];&nbsp; &nbsp; &nbsp; &nbsp; if (move_uploaded_file($_FILES['userfile']['tmp_name'][$ct], $uploadfile)) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $mail->addAttachment($uploadfile, $filename);&nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $msg .= 'Failed to move file to ' . $uploadfile;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }// Altered e-mail to recipient 2&nbsp; &nbsp; $mail->ClearAddresses(); // avoid recipient 1 getting this altered mail&nbsp; &nbsp; $mail->addAddress('[e-mail]');&nbsp; &nbsp; $mail->Subject = 'New subject overwriting the first one';&nbsp; &nbsp; $mail->Body = 'New body overwriting the first one';&nbsp; &nbsp; $mail->send(); // send both mails这样，同一封邮件基本上会发送两次，包括附件，但会通过覆盖（例如，主题和正文）进行一些更改。

发送第一封邮件时，您已将上传的文件从临时存储区中移出，因此在第二次尝试中不再存在。move_uploaded_file($_FILES['userfile']['tmp_name'][$ct],&nbsp;$uploadfile)您需要先移动上载的文件，然后使用该变量$uploadfile两次。您实际上应该将所有这些放到一个函数中，这样您也不会重复自己。
