如何附加两个或多个文件并用PHP发送邮件

Question

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);

<form action="#" method="POST" enctype="multipart/form-data"  >
 <input type="file" name="csv_file[]" />
 <br/>

 <input type="file" name="csv_file[]" />
 <br/>

 <input type="file" name="csv_file[]" />
 <br/>

 <input type="submit" name="upload" value="Upload" />
 <br/>

</form> 

<?php

if($_POST) {

    for($i=0; $i < count($_FILES['csv_file']['name']); $i++){

        $ftype[]       = $_FILES['csv_file']['type'][$i];
        $fname[]       = $_FILES['csv_file']['name'][$i];

    }


    // array with filenames to be sent as attachment
    $files = $fname;

    // email fields: to, from, subject, and so on
    $to = "example@gmail.com";
    $from = "example@gmail.com"; 
    $subject ="My subject"; 
    $message = "My message";
    $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/plain; 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>"; 
    } 



}

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 = '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';

在核心php邮件功能中检查以下多文件附件.

<?php
/** Mail with attachment */
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 {
        //echo "mail send ... ERROR!";
        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托管服务器空间中上载来给您带来自由。这是非常需要的。

有很多解决方案可以告诉您如何将文件上传到服务器，然后再发送给电子邮件，但是此解决方案提供了“将多个文件直接附加到电子邮件 ”
