【问题描述】：

我正在使用具有邮件附件选项的 php 代码。当我有一个附件时，一切都很好，但是当我有两个或更多时，我只收到其中一个。另外，发送邮件时回显消息有问题，我没有收到任何消息。这是我使用的代码：

<?php

if ($_SERVER['REQUEST_METHOD']=="POST")

  $to="[e-mail]";
  $subject="Online Prijava";
  $from = stripslashes($_POST['ime'])."<".stripslashes($_POST['email_adresa']).">";

  if(empty($_POST['ime']) || empty($_POST['email_adresa']))
  
    $errors .= "\n Greska: nisu uneta sva obavezna polja";
  

  $mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

  $tmp_name = $_FILES['fotokopija_uplatnice']['tmp_name'];
  $type = $_FILES['fotokopija_uplatnice']['type'];
  $file_name = $_FILES['fotokopija_uplatnice']['name'];
  $size = $_FILES['fotokopija_uplatnice']['size'];

  $message = "PODACI U PSU:
\n Razred: " .$_POST['razred']. "
\n Boja: " .$_POST['boja']. "
\n Tip dlake: " .$_POST['tip_dlake']. "
\n Velicina: " .$_POST['velicina']. "
\n Pol: " .$_POST['pol']. "

\n

\n Email adresa: " .$_POST['email_adresa'];

  $headers = "From: $from\r\n";

  if (file_exists($tmp_name))
    if(is_uploaded_file($tmp_name))
      $file = fopen($tmp_name,'rb');
      $data = fread($file,filesize($tmp_name));
      fclose($file);
      $data = chunk_split(base64_encode($data));
    

    $headers .= "MIME-Version: 1.0\r\n" .
      "Content-Type: multipart/mixed;\r\n" .
      " boundary=\"$mime_boundary\"";

    $message .= "\n\n\nThis is a multi-part message in MIME format.\n\n" .
      "--$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" .
      "Content-Type: $type;\n" .
      " name=\"$file_name\"\n" .
      //"Content-Disposition: attachment;\n" .
      //" filename=\"$fileatt_name\"\n" .
      "Content-Transfer-Encoding: base64\n\n" .
      $data . "\n\n" .
      "--$mime_boundary--\n";
  

  if (mail($to, $subject, $message, $headers))
  
    echo '<div><center><h1>Prijava uspesno poslata.</h1></center></div>';
   else 
    echo '<div><center><h1>Greska prilikom slanja prijave. Molimo pokusajte ponovo.</h1></center></div>';
  


?>

【参考方案1】：

我遇到了一些问题。我使用 phpmailer 解决了它

<?php 
require "classes/class.phpmailer.php"; // include the class name
$mail = new PHPMailer();
$mail->isSMTP();    
$mail->SMTPAuth = true;                                 
$mail->Host = 'xx';           
$mail->Username = 'xxxx'; 
$mail->Password = 'xx';
$mail->Port = xxx;
$mail->setFrom('ixx@.123com','ixx@.123com');
$mail->addAddress('ixx@.123com','ixx@.123com');
$mail->AddAttachment("1.jpg"); //Attach a file here
$mail->AddAttachment("2.jpg"); //Attach a file here
$mail->AddAttachment("3.jpg"); //Attach a file here
$mail->AddAttachment("4.jpg"); //Attach a file here
$mail->Msghtml("<b>Two Attachment. Great Job!.. <br/>"); //Put your body of the message you can place html code here
//send the message, check for errors
$mail->IsHTML(true);
if (!$mail->send()) 
echo "Mailer Error: " . $mail->ErrorInfo;
 else 
echo "SENDING";

?>

您可以使用外部 SMTP，例如 mandrill 或 Google SMTP，也可以使用您的服务器 SMTP。

这里有一个不错的 phpmailler 教程。

【讨论】：

只能用于附件吗？我对 php 不是很好，大部分代码都是我的朋友写的，他不在这里 atm 所以我卡住了……我不确定我能不能做到：S

【参考方案2】：

这是有效的代码

<?php
if ($_SERVER['REQUEST_METHOD']=="POST")

$to="[e-mail]";
$subject="Online Prijava";
$from = stripslashes($_POST['ime'])."<".stripslashes($_POST['email_adresa']).">";

// generate a random string to be used as the boundary marker
 $mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

// now we'll build the message headers
$headers = "From: $from\r\n" .
 "MIME-Version: 1.0\r\n" .
  "Content-Type: multipart/mixed;\r\n" .
  " boundary=\"$mime_boundary\"";

// here, we'll start the message body.
// this is the text that will be displayed
// in the e-mail
  $message = "PODACI U PSU:
\n Razred: " .$_POST['razred']. "
\n Boja: " .$_POST['boja']. "
\n Tip dlake: " .$_POST['tip_dlake']. "
\n Velicina: " .$_POST['velicina']. "
\n Pol: " .$_POST['pol']. "
\n Visina: " .$_POST['visina']. "
\n Tezina: " .$_POST['tezina']. "
\n Ime psa: " .$_POST['ime_psa']. "
\n Broj pedigra: " .$_POST['broj_pedigrea']. "
  \n Datum rodjenja: " .$_POST['datum_rodjenja']. "
\n Otac: " .$_POST['otac']. "
\n Broj pedigrea oca: " .$_POST['broj_pedigrea_oca']. "
\n Majka: " .$_POST['majka']. "
\n Broj pedigra majke: " .$_POST['broj_pedigra_majke']. "
\n Odgajivac: " .$_POST['odgajivac']. "
\n
\nPODACI O VLASNIKU
\n Ime: " .$_POST['ime']. "

\n Grad: " .$_POST['grad']. "
\n Drzava: " .$_POST['drzava']. "
\n Telefon: " .$_POST['telefon']. "
\n Email adresa: " .$_POST['email_adresa'];

// next, we'll build the invisible portion of the message body
// note that we insert two dashes in front of the MIME boundary
// when we use it
$message = "This is a multi-part message in MIME format.\n\n" .
  "--$mime_boundary\n" .
  "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .

$message . "\n\n";

// now we'll process our uploaded files
foreach($_FILES as $userfile)
  // store the file information to variables for easier access
  $tmp_name = $userfile['tmp_name'];
  $type = $userfile['type'];
  $name = $userfile['name'];
  $size = $userfile['size'];

  // if the upload succeded, the file will exist
  if (file_exists($tmp_name))

     // check to make sure that it is an uploaded file and not a system file
     if(is_uploaded_file($tmp_name))

        // open the file for a binary read
        $file = fopen($tmp_name,'rb');

        // read the file content into a variable
        $data = fread($file,filesize($tmp_name));

        // close the file
        fclose($file);

        // now we encode it and split it into acceptable length lines
        $data = chunk_split(base64_encode($data));
     

     // now we'll insert a boundary to indicate we're starting the attachment
     // we have to specify the content type, file name, and disposition as
     // an attachment, then add the file content.
     // NOTE: we don't set another boundary to indicate that the end of the
     // file has been reached here. we only want one boundary between each file
     // we'll add the final one after the loop finishes.
     $message .= "--$mime_boundary\n" .
        "Content-Type: $type;\n" .
        " name=\"$name\"\n" .
        "Content-Disposition: attachment;\n" .
        " filename=\"$fileatt_name\"\n" .
        "Content-Transfer-Encoding: base64\n\n" .
     $data . "\n\n";
   

// here's our closing mime boundary that indicates the last of the message
$message.="--$mime_boundary--\n";
// now we just send the message
if (mail($to, $subject, $message, $headers))
  echo "Message Sent";
else
  echo "Failed to send";
