無法將消息正文添加到PHP而不會丟失附件

Question

我終於拼湊了一段代碼，該代碼允許我從我的服務器發送FDF文件到電子郵件，該文件不會將我的文件減少到0kb附件。問題是，我必須擺脫電子郵件的身體才能做到這一點。

我希望能夠將HTML（或純文本）正文添加到正在發送的電子郵件中。像種類：

<h2>DWR Submittal</h2> 
<p>Process the attachment in the system.</p> 

STEP 1. Download file 
STEP 2. Open with Adobe Acrobat 
STEP 3. Verify form data 
STEP 4. etc... 
STEP 5. etc... 

在哪裏或者怎麼會這樣不會影響附件進行

<?php 
    $fileatt = './dwrdocuments/dwr.fdf'; // Path to the file 
    $fileatt_type = "application/octet-sdiveam"; // File Type 
    $fileatt_name = date(mdy_his).'_dwr.fdf'; 
    $email_from = $_POST['From']; // Who the email is from 
    $email_subject = 'DWR Submittal'; // The Subject of the email 
    $email_txt = $_POST['Comments']; // Message that the email has in it 

    $email_to = 'admin@example.com'; // Who the email is to 

    $headers = "From: ".$email_from; 

    $file = fopen($fileatt,'rb'); 
    $data = fread($file,filesize($fileatt)); 
    fclose($file); 

    $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}\""; 

    $email_message .= "This is a multi-part message in MIME format.\n\n" . 
    "--{$mime_boundary}\n" . 
    "Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
    "Content-divansfer-Encoding: 7bit\n\n" . 
    $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-Disposition: attachment;\n" . 
    //" filename=\"{$fileatt_name}\"\n" . 
    "Content-Transfer-Encoding: base64\n\n" . 
    $data . "\n\n" . 
    "--{$mime_boundary}--\n"; 

    $ok = @mail($email_to, $email_subject, $email_message, $headers); 
    header ("Location: ../confirm.html"); 
?>

嘗試增加：

$email_message .= '<h2>DWR Submittal</h2> 
<p>Process the attachment in the system.</p> 

STEP 1. Download file 
STEP 2. Open with Adobe Acrobat 
STEP 3. Verify form data 
STEP 4. etc... 
STEP 5. etc...'; 

權利之前：

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