I am trying to make it so users can upload files using a form - though I only want to accept .rtf files. I have tried everything I can think of or find to accomplish this, but to no avail. At this point, I am pretty sure I am in over my head. Any help you could provide to doctor this script would be greatly appreciated.
// Read POST request params into global vars
$to = $POST['to'];
$from = $POST['from'];
$subject = $POST['subject'];
$message = $POST['message'];
// Obtain file upload vars
if($_FILES['fileatt']['type'] == "application/rtf") {
// file is rtf
} else {
// file is not rtf
}
$fileatt = $FILES['fileatt']['tmp_name'];
$fileatt_name = $FILES['fileatt']['name'];
$headers = "From: $from";
//If file exists...
if(file_exists($fileatt)) {
// Read the file to be attached ('rb' = read binary)
$file = fopen($fileatt,'rb');
if (is_uploaded_file($fileatt)) {
$data = fread($file,filesize($fileatt));
fclose($file);
// Generate a boundary string
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// Add the headers for a file attachment
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
// Add a multipart boundary above the plain message
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";
// Base64 encode the file data
$data = chunk_split(base64_encode($data));
// Add file attachment to the message
$message .= "--{$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";
}}
