Trouble with encoding

[c_pattle]

Hey everyone

 

I've got a loop that loops through attachments and then sends them by email.  When I sent it to my address the attachments got there fine.  However when I sent it to a different address the attachments got there but were all empty as if they hadn't been encoded properly.  Do you think this could be problem with my script or a problem with the different email addresses?  I've copied my script below. 

 

$to = "[email protected]"; 
$subject = "You have been sent some content by " . $_REQUEST['order_company_name']; 
$email = $_REQUEST['order_email'] ; 

foreach ($_FILES['att']['error'] as $key => $error) {
  if (UPLOAD_ERR_OK === $error) {

$att_path = $_FILES['att']['tmp_name'][$key];
$att_name = $_FILES['att']['name'][$key];
$att_size = $_FILES['att']['size'][$key];
$att_type = $_FILES['att']['type'][$key];

$fp = fopen( $att_path, "rb");
$file = fread( $fp, $att_size );
fclose ($fp);

$num = md5(time());
$str = "==multipart_Boundary_x{$num}x";

$file = chunk_split(base64_encode($file));

$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: multipart/mixed;";
$headers .= "boundary=\"{$str}\"\r\n";
$headers .= "From: $email"; 

$msg .= "This is a multi-part message in MIME format\r\n\n";
$msg .= "--{$str}\r\n";
$msg .= "Content-Type: text/plain; charset=\"iso-8859-1\"\r\n";
$msg .= "Content-Transfer-Encoding: 8bit\r\n";
$msg .= "--{$str}\r\n";

$msg .= "Content-Type: {$att_type}; ";
$msg .= "name=\"{$att_name}\"\r\n";
$msg .= "Content-Disposition: attachment; ";
$msg .= "filename =\"{$att_name}\"\r\n";
$msg .= "Content-Transfer-Encoding: base64\r\n";
$msg .= "$file\r\n\n";
$msg .= "--{$str}";

$sent = mail($to, $subject, $msg, $headers) ; 
if($sent) 
{print "<p>Thank you.  Your attachment was sent successfully</p>"; }
else 
{print "<p>Sorry.  We encountered an error sending your mail</p>"; }

$msg = "";
$headers = "";
}
}

 

Thanks for any help

You may use this function. It works already tested.

 

<?php
