php 如何在PHP中附加两个或多个文件并发送邮件

How to attach two or multiple files and send mail in PHP

提问by user3309116

The code below sends only one attachment, but I need to attach and send two file(one rar file and pdf)

下面的代码只发送一个附件，但我需要附加并发送两个文件（一个 rar 文件和 pdf）

$email_to = "$email"; // The email you are sending to (example)
$email_from = "[email protected]"; // The email you are sending from (example)
$email_subject = "subject line"; // The Subject of the email
$email_txt = "text body of message"; // Message that the email has in it
$fileatt = "files/example.rar"; // Path to the file (example)
$fileatt_type = "application/x-rar-compressed"; // File Type
$fileatt_name = "example.rar"; // Filename that will be used for the file as the attachment
$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers="From: $email_from"; // Who the email is from (example)
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" . $email_txt;
$email_message .= "\n\n";
$data = chunk_split(base64_encode($data));
$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";

mail($email_to,$email_subject,$email_message,$headers);

Following the reusability principles, you can use https://github.com/Synchro/PHPMailer

遵循可重用性原则，您可以使用https://github.com/Synchro/PHPMailer

<?php
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup server
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'jswan';                            // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable encryption, 'ssl' also accepted

$mail->From = '[email protected]';
$mail->FromName = 'Mailer';
$mail->addAddress('[email protected]', 'Josh Adams');  // Add a recipient
$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name                               

$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.';

Check the following Multiple file attachment in core php mail function.

检查核心php邮件功能中的以下多个文件附件。

<?php

function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $bcc, $subject, $message){    
    $uid = md5(uniqid(time()));
    $mime_boundary = "==Multipart_Boundary_x{$uid}x"; 

    $header = "From: ".$from_name." <".$from_mail.">\r\n";
    $header .= "Bcc: ".$bcc."\r\n";
    $header .= "Reply-To: ".$replyto."\r\n";
    $header .= "MIME-Version: 1.0\r\n";

This is one of the best solution i got for multiple mail attachment and tested successfully.

这是我为多个邮件附件获得并成功测试的最佳解决方案之一。

This code gives you freedom by attaching file in email without uploading in your hosting server space. Which is highly needed.

此代码通过在电子邮件中附加文件而无需在您的托管服务器空间中上传，从而为您提供自由。这是非常需要的。

There are many solution telling how to upload files to your server and then send to email, but this solution gives "Direct multiple file attachment to email"

有很多解决方案告诉如何将文件上传到您的服务器然后发送到电子邮件，但是这个解决方案提供了“直接将多个文件附件发送到电子邮件”

FYI, this line from the original post, as well as some of the answers, will cause a problem on some email systems.

仅供参考，原始帖子中的这一行以及一些答案会导致某些电子邮件系统出现问题。

$headers .= "\nMIME-Version: 1.0\n" .

$headers .= "\nMIME-Version: 1.0\n" 。

The \n at the beginning caused the attachments to fail when sending to an address hosted at emailpros.com, a secure HIPAA compliant email system. Simply removing the line break fixed the issue there. However, it had been working just fine when sending to a Gmail account and another host (Hostmonster). This way worked just fine on all of them. $headers .= "MIME-Version: 1.0\n" .

开头的 \n 导致附件在发送到 emailpros.com（一个符合 HIPAA 的安全电子邮件系统）托管的地址时失败。只需删除换行符即可解决该问题。但是，在发送到 Gmail 帐户和另一台主机 (Hostmonster) 时，它一直工作得很好。这种方式对所有这些都很好。$headers .= "MIME-Version: 1.0\n" 。

Try this out. Put your files in an array, then using a form loop add each of them in the $email_messagevariable

试试这个。将您的文件放在一个数组中，然后使用表单循环将每个文件添加到$email_message变量中

$email_to = "$email"; // The email you are sending to (example)
$email_from = "[email protected]"; // The email you are sending from (example)
$email_subject = "subject line"; // The Subject of the email
$email_message = "text body of message"; // Message that the email has in it
$files = array("file_1.ext","file_2.ext","file_3.ext",......);
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers="From: $email_from"; // Who the email is from (example)
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" . $email_txt;
$email_message .= "\n\n";
    for($x=0;$x<count($files);$x++){
    $file = fopen($files[$x],"rb");
    $data = fread($file,filesize($files[$x]));
    fclose($file);
    $data = chunk_split(base64_encode($data));
    $email_message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" .
    "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" .
    "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
    $email_message .= "--{$mime_boundary}\n";
    }

mail($email_to,$email_subject,$email_message,$headers);

Hope it works fine :)

希望它工作正常:)

This is the code I am using to send multiple attachments, I hope this helps you too. You actually need to use a loop at attach multiple files.

这是我用来发送多个附件的代码，我希望这对您也有帮助。您实际上需要在附加多个文件时使用循环。

    $files = array("file1.pdf","file2.pdf");
    $body = "email in html form";

    // email fields: to, from, subject, and so on
    $to = "e-mail id of person you are sending to";
    $from = "your e-mail id";
    $subject = "email subject";
    $message = html_entity_decode($body);
    $headers = "From: $from";

    // boundary
    $semi_rand = md5(time());
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

   // headers for attachment
    $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"   {$mime_boundary}\"";

    // multipart boundary
    $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";
    $message .= "--{$mime_boundary}\n";

    // preparing attachments
    for ($x = 0; $x < count($files); $x++) {
        $file = fopen($files[$x], "rb");

<input type="file" name="file" multiple> //select multiple file
$target_dir = "upload/"; //first upload your directory path
$names =  $_FILES['file']['name'];   //file Name
$i =0;
foreach($names as $name){
$target_file = $target_dir . basename($name); //first upload your     
directory path
move_uploaded_file($_FILES["file"]["tmp_name"][$i], $target_file);  
//upload your directory         
$mail->addAttachment($target_file); //after upload file path 
fetch and   atachment
$i++;

Simple working and tested example:

简单的工作和测试示例：

<?php
  mail_attachment("[email protected]","Subject","Here is the body",array("file1.pdf","file2.pdf"));
  function mail_attachment($to, $subject, $message, $files) {

      $semi_rand = md5(time()); 
      $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
      $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; 

      $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; 
      $message .= "--{$mime_boundary}\n";

      foreach ($files as $file) {

        $filename = end(explode("/",$file));  
        $data = file_get_contents($file);

        $data = chunk_split(base64_encode($data));

        $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$file\"\n" .
