如何附加两个或多个文件并用PHP发送邮件

标签： php attachment email-attachments

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 = "online@example.co.in"; // 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);

在reusability principles之后，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 = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('josh@example.net', '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.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;
   exit;
}

echo 'Message has been sent';

检查核心php邮件功能中的以下多文件附件。

<?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";
    $header .= "Content-Type: multipart/mixed; boundary=\"".$mime_boundary."\"\r\n\r\n";
    $header .= "This is a multi-part message in MIME format.\r\n";
    $header .= "--".$mime_boundary."\r\n";
    $header .= "Content-type:text/html; charset=iso-8859-1\r\n";
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
    $header .= nl2br($message)."\r\n\r\n";
    $header .= "--".$mime_boundary."\r\n";

    foreach($filename as $k=>$v){

        $file = $path.$v;
        $file_size = filesize($file);
        $handle = fopen($file, "r");
        $content = fread($handle, $file_size);
        fclose($handle);
        $content = chunk_split(base64_encode($content));

        $header .= "Content-Type: application/octet-stream; name=\"".$v."\"\r\n"; // use different content types here
        $header .= "Content-Transfer-Encoding: base64\r\n";
        $header .= "Content-Disposition: attachment; filename=\"".$v."\"\r\n\r\n";
        $header .= $content."\r\n\r\n";
        $header .= "--".$mime_boundary."--"."\r\n";
    } 

    if (mail($mailto, $subject, "", $header)) {
        //echo "mail send ... OK"; // or use booleans here
        return true;
    } else {

        return false;

这是我获得多个邮件附件并成功测试的最佳解决方案之一。

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来为您提供自由。这是非常需要的。

有许多解决方案告诉您如何将文件上传到服务器然后发送到电子邮件，但此解决方案提供“直接多个文件附件到电子邮件”

试一试。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 = "online@example.co.in"; // 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);

希望它运作良好：）

这是我用来发送多个附件的代码，我希望这对你也有帮助。实际上，您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");
        $data = fread($file, filesize($files[$x]));
        fclose($file);
        $data = chunk_split(base64_encode($data));
        $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" .
            "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" .
            "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
        $message .= "--{$mime_boundary}\n";
    }

    // send

    $ok = @mail($to, $subject, $message, $headers);
    if ($ok) {
        echo "<p>mail sent to $to!</p>";
    } else {
        echo "<p>mail could not be sent!</p>";
    }

仅供参考，原始帖子中的这一行以及一些答案将导致某些电子邮件系统出现问题。

$ headers。=“\ nMIME-Version：1.0 \ n”。

开头的\ n在发送到emailpros.com（一个安全的HIPAA兼容电子邮件系统）托管的地址时导致附件失败。只需删除换行符就可以解决问题。但是，在发送到Gmail帐户和其他主机（Hostmonster）时，它一直运行正常。 这种方式对所有这些都很好。 $ headers。=“MIME-Version：1.0 \ n”。
