问题描述

发送带有多个附件的电子邮件时遇到问题。这是代码：

 <？php 
 
 if（isset（$ _ POST ['sendEmail ']））
 {
 
 foreach（$ _ FILES ['uploadEmail'] ['error'] as $ key => $ value）{
 if（！$ _ FILES ['uploadEmail'] ['error'] [$ key]）{
 $ target_path =; 
 $ target_path = $ target_path。 basename（$ _FILES ['uploadEmail'] ['name'] [$ key]）; 
 if（move_uploaded_file（$ _ FILES ['uploadEmail'] ['tmp_name'] [$ key]，$ target_path））{
 $ files [] = $ _FILES ['uploadEmail'] ['name' ] [$关键] 
} 
} 
} 
 
 $ toEmails = explode（，，$ _ POST ['toEmail']）; 
 $ count = count（$ toEmails）; 
 $ i = 0; $ j = 1; $ k = 100; 
 $ bcc =''; 
 while（$ i< $ count）{
 $ bcc。= $ toEmails [$ i]。，; 
 if（$ j == $ k || $ i == $ count-1）{
 $ j = 1; 
 // echo $ bcc。'< br />'.$sub.'<br />'.$message.'<br />< br />'; 
 $ from ='test@gmail.com'; 
 $ sub = $ _POST ['subject']; 
 $ message = $ _POST ['message'];

我收到邮件但找不到任何附件。
有没有人知道可能是什么问题？

这是一封电子邮件正文，邮件内容如下：

I received mail but could not find any attachments with it.
Does anyone know what could be wrong?

Here is an email body which I got in mail:
MIME-Version: 1.0 Content-Type: multipart/mixed; 
boundary="==Multipart_Boundary_x2d454346f03d2c19cfefc838ce4d8623x"

This is a multi-part message in MIME format.

--==Multipart_Boundary_x2d454346f03d2c19cfefc838ce4d8623x Content-Type: text/html; charset="iso-8859-1"

Content-Transfer-Encoding: base64




--==Multipart_Boundary_x2d454346f03d2c19cfefc838ce4d8623x

 解决方案 
I propose to use PHPMailer for sending mails with attachements:
<?php

require 'PHPMailerAutoload.php';                      // If this file is not located in the same directory, use __DIR__ . "/path/to/PHPMailerAutoload.php"

$mail = new PHPMailer;

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('joe@example.net', 'Joe User');     // Add a recipient
$mail->addAddress('ellen@example.com');               // Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');

$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

?>
