E-mail File Attachment Not Working

[ccgorman]

I use this code on a number of sites and it works fine. But I uploaded it to a new server and now it doesn't work. Basically the code attaches a file that the user has uploaded with a form to an e-mail and sends it on. On this server I get a blank file attachment returned to me. Perhaps someone knows what the problem is without even looking at the code, but here it is.

class CMailFile {
var $subject;
var $addr_to;
var $text_body;
var $text_encoded;
var $mime_headers;
var $mime_boundary = "--==================846811060==";
var $smtp_headers;

	function CMailFile($subject,$to,$from,$msg,$filename,$mimetype = "application/octet-stream", $mime_filename = false) {
		$this->subject = $subject;
		$this->addr_to = $to;
		$this->smtp_headers = $this->write_smtpheaders($from);
		$this->text_body = $this->write_body($msg);
		$this->text_encoded = $this->attach_file($filename,$mimetype,$mime_filename);
		$this->mime_headers = $this->write_mimeheaders($filename, $mime_filename);
	}

	function attach_file($filename,$mimetype,$mime_filename) {
		$encoded = $this->encode_file($filename);
		if ($mime_filename) $filename = $mime_filename;
		$out = "--" . $this->mime_boundary . "\n";
		$out = $out . "Content-type: " . $mimetype . "; name=\"$filename\";\n";		
		$out = $out . "Content-Transfer-Encoding: base64\n";
		$out = $out . "Content-disposition: attachment; filename=\"".$GLOBALS["name"].".doc\"\n\n";
		$out = $out . $encoded . "\n";
		$out = $out . "--" . $this->mime_boundary . "--" . "\n";
		return $out; 
		// added -- to notify email client attachment is done
	}

	function encode_file($sourcefile) {
		if (is_readable($sourcefile)) {
			$fd = fopen($sourcefile, "r");
			$contents = fread($fd, filesize($sourcefile));
			$encoded = my_chunk_split(base64_encode($contents));
			fclose($fd);	
		}
		return $encoded;
	}

	function sendfile() {
		$headers = $this->smtp_headers . $this->mime_headers;		
		$message = $this->text_body . $this->text_encoded;
		mail($this->addr_to,$this->subject,$message,$headers);
	}

	function write_body($msgtext) {
		$out = "--" . $this->mime_boundary . "\n";
		$out = $out . "Content-Type: text/plain; charset=\"us-ascii\"\n\n";
		$out = $out . $msgtext . "\n";
		return $out;
	}

	function write_mimeheaders($filename, $mime_filename) {
		if ($mime_filename) $filename = $mime_filename;
		$out = "MIME-version: 1.0\n";
		$out = $out . "Content-type: multipart/mixed; ";
		$out = $out . "boundary=\"$this->mime_boundary\"\n";
		$out = $out . "Content-transfer-encoding: 7BIT\n";
		$out = $out . "X-attachments: $filename;\n\n";
		return $out;
	}

	function write_smtpheaders($addr_from) {
		$out = "From: $addr_from\n";
		$out = $out . "Reply-To: $addr_from\n";
		$out = $out . "X-Mailer: PHP3\n";
		$out = $out . "X-Sender: $addr_from\n";
		return $out;
	}
}
function my_chunk_split($str) {
	$stmp = $str;
	$len = strlen($stmp);
	$out = "";
	while ($len > 0) {
		if ($len >= 76) {
			$out = $out . substr($stmp, 0, 76) . "\r\n";
			$stmp = substr($stmp, 76);
			$len = $len - 76;
		}
		else {
			$out = $out . $stmp . "\r\n";
			$stmp = ""; $len = 0;
		}
	}
	return $out;
}

$newmail = new CMailFile($subject,$sendto,$replyto,$message,$cv_upload,$mimetype);
$newmail->sendfile();
