使用php附加文件到邮件

Question

我创建了一个包含上传字段文件和其他一些文本字段的表单。我使用PHP通过电子邮件发送表单的数据并附加文件。

这是我正在使用的代码，但它不能正常工作。该文件通常附加到消息，但其余数据不会发送。

$body="bla bla bla"; 

$attachment = $_FILES['cv']['tmp_name']; 
$attachment_name = $_FILES['cv']['name']; 
if (is_uploaded_file($attachment)) { 
    $fp = fopen($attachment, "rb"); 
    $data = fread($fp, filesize($attachment)); 
    $data = chunk_split(base64_encode($data)); 
    fclose($fp); 
} 

$headers = "From: $email<$email>\n"; 
$headers .= "Reply-To: <$email>\n"; 
$headers .= "MIME-Version: 1.0\n"; 
$headers .= "Content-Type: multipart/related; type=\"multipart/alternative\"; boundary=\"----=MIME_BOUNDRY_main_message\"\n"; 
$headers .= "X-Sender: $first_name $family_name<$email>\n"; 
$headers .= "X-Mailer: PHP4\n"; 
$headers .= "X-Priority: 3\n"; 
$headers .= "Return-Path: <$email>\n"; 
$headers .= "This is a multi-part message in MIME format.\n"; 
$headers .= "------=MIME_BOUNDRY_main_message \n"; 
$headers .= "Content-Type: multipart/alternative; boundary=\"----=MIME_BOUNDRY_message_parts\"\n"; 

$message = "------=MIME_BOUNDRY_message_parts\n"; 
$message .= "Content-Type: text/html; charset=\"utf-8\"\n"; 
$message .= "Content-Transfer-Encoding: quoted-printable\n"; 
$message .= "\n"; 
$message .= "$body\n"; 
$message .= "\n"; 
$message .= "------=MIME_BOUNDRY_message_parts--\n"; 
$message .= "\n"; 
$message .= "------=MIME_BOUNDRY_main_message\n"; 
$message .= "Content-Type: application/octet-stream;\n\tname=\"" . $attachment_name . "\"\n"; 
$message .= "Content-Transfer-Encoding: base64\n"; 
$message .= "Content-Disposition: attachment;\n\tfilename=\"" . $attachment_name . "\"\n\n"; 
$message .= $data; //The base64 encoded message 
$message .= "\n"; 
$message .= "------=MIME_BOUNDRY_main_message--\n"; 

$subject = 'bla bla bla'; 
$to="test@test.com"; 
mail($to,$subject,$message,$headers); 

为什么没有发送$ body数据？你能帮我解决吗？

嗯，我会建议使用PEAR Mail_Mime包......它抽象一切了......

至于你确切的问题，我猜那是因为你有两个不同的边界和两个内容 - 在标题部分中输入标题。尝试生成这样的事情：

MIME-Version: 1.0 
Content-Type: multipart/mixed; boundary="------=MIME_BOUNDARY_MESSAGE_PARTS" 

------=MIME_BOUNDARY_MESSAGE_PARTS 
Content-Type: text/html charset="utf-8" 

$body 

------=MIME_BOUNDARY_MESSAGE_PARTS 
Content-Type: application/octet-stream;name="filename" 
Content-Transfer-Encoding: base64 
... 
$data 

------=MIME_BOUNDARY_MESSAGE_PARTS
