PHP电子邮件内容作为附件到达

Question

我有这段PHP代码，尽管可以工作，但是问题是电子邮件内容与预期的附件一起作为附件发送，这意味着当电子邮件到达时，正文为空，但是有两个附件。 一个是预期的附件，另一个是应该显示在电子邮件中的电子邮件内容。 我做错了什么吗？

这是完整的源代码：

<?php
require('fpdf/fpdf.php');
include('./config.php');

$pdf = new FPDF('P', 'pt', 'Letter');
$pdf->SetAutoPageBreak(true, $margin);

$pdf->AddPage();
$pdf->SetFont('arial','',12);

   if(isset($_POST['accept'])){
    $id = $_POST['id'];
    $to = 'me@somewhere.com';
    $subject = urldecode($_POST['subject']);
    $message = urldecode($_POST['message']);

    $data = '';

    $result = mysql_query("select * from applications where id = $id");
    $row = $data_array = mysql_fetch_assoc($result);

    $data .= "Name: " . $row['name'] . " \n\n";
    $data .= "Surname: " . $row['surname'] . "\n\n";    
    $data .= "Age: ". $row['age'] . "\n\n";
    $data .= "Dob: ". $row['dob'] . "\n\n"; 
    $data .= "Height: ". $row['height'] . "\n\n";
    $data .= "Add1 : ".$row['address1'] . "\n\n";   
    $data .= "Add2:  ".$row['address2'] . "\n\n";   
    $data .= "Add3: ".$row['address3'] . "\n\n";
    $data .= "Postcode: ".$row['postcode'] . "\n\n";            
    $data .= "Town:  ".$row['town'] . "\n\n";   
    $data .= "County: ". $row['county']. "\n\n";    
    $pdf->SetX(140);

    $pdf->Ln(2);

    $pdf->MultiCell(0, 15, $data);

    $from     = "me@mydomain.com"; 

    $separator = md5(time());

    $eol = PHP_EOL;

    // attachment name
    $filename = "form.pdf";

    // encode data (puts attachment in proper format)
    $pdfdoc = $pdf->Output("", "S");
    $attachment = chunk_split(base64_encode($pdfdoc));

    // main header
    $headers  = "From: ".$from.$eol;
    $headers .= "MIME-Version: 1.0".$eol; 
    $headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"";

    $body = "--".$separator.$eol;
    $body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;

    // message
    $body .= "--".$separator.$eol;
    $body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
    $body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
    $body .= $message.$eol;

    // attachment
    $body .= "--".$separator.$eol;
    $body .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol; 
    $body .= "Content-Transfer-Encoding: base64".$eol;
    $body .= "Content-Disposition: attachment".$eol.$eol;
    $body .= $attachment.$eol;
    $body .= "--".$separator."--";

    // send message
    if(mail($to, $subject, $body, $headers)){

                echo "<b>Email successfully sent</b>";
        }
    else{
         echo "Your message could not be sent.";
      }
}

?>

任何帮助将不胜感激。

实际上，我有从头开始单手编写此类内容的经验。 经过多年维护自制的PHP电子邮件生成器之后，我的建议是您不应该这样做。 与编写自己的（并花费您的时间和/或资源来支付所有固有的错误）相比，今天（无论何时）研究和找到最受支持的主流解决方案所花费的时间和资源肯定更少。
