Question

所以我正在尝试邮寄带附件的表单，但当我在邮件中包含$ header时，它无法发送：mail("mohd.gadiwala@techmatters.com", $subject, $message, $headers) 当我从我的代码邮件中删除$ header时，发送的图像附件是文本数据，而不是实际的附件图像png form.Everything塞满了边界我试过这个网站的代码：{{3} } 我在下面的代码中做错了什么？：

<?php
 if(isset($_POST['submit']) && $_POST['submit']=='Submit')

{

$to="siva.garre@livait.net";
$subject="File sent by ".$_POST['name'];

// get the sender's name and email address
 // we'll just plug them a variable to be used later

 $from = stripslashes($_POST['name'])."<".stripslashes($_POST['email']).">";

$name = $_POST['name'];
 $email_address = $_POST['email'];
 $message = $_POST['comment'];

// generate a random string to be used as the boundary marker
 $mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";
 if($_FILES['filename']['tmp_name'] != ''){
 // store the file information to variables for easier access
 $tmp_name = $_FILES['filename']['tmp_name'];
 $type = $_FILES['filename']['type'];
 $file_name = $_FILES['filename']['name'];
 $size = $_FILES['filename']['size'];
 }
 // here we'll hard code a text message
 // again, in reality, you'll normally get this from the form submission

if($tmp_name != ''){
 $message = "nn Name: $name nn Email: $email_address nnMessage: nn $message nnHere is your file: $file_name";
 }
 else{
 $message = "nn Name: $name nn Email: $email_address nnMessage: nn $message.";
 }
 // if the upload succeded, the file will exist
 if($tmp_name != ''){
 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 build the message headers
  $headers = "From: $fromrn";
if( $tmp_name != '' ){
$headers .= "MIME-Version: 1.0rn" .
"Content-Type: multipart/mixed;rn" ;

// next, we'll build 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.nn" .
 "Content-Type:text/plain;charset=iso-8859-1" .
 "Content-Transfer-Encoding: 7bitnn" .
 $message . "nn";

// 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 and set another boundary to
 // indicate that the end of the file has been reached

$message .=
 "Content-Type: ".$type."" .
 " name=".$file_name."n" .
 //"Content-Disposition: attachment;n" .
 //" filename="{$fileatt_name}"n" .
 "Content-Transfer-Encoding: base64nn" .
 $data . "nn" ;
 }
 // now we just send the message
 if (mail("mohd.gadiwala@techmatters.com", $subject, $message, $headers))
 echo "<div class='msg msg-ok'><p><strong>Message Sent</strong></p></div><br><br>";
 else
 echo "<div class='msg msg-ok'><p><strong>Message sending failed</strong></p></div><br><br>";
 }
