Emailing an uploaded file, file corrupted

[dmikester1]

I need some help with emailing an uploaded file.  The file is always corrupted and just a few bytes, when it is normally a few KB.  I would prefer not to use the PHP mailer class so I can learn myself how to do the coding. 

Thanks

Mike

 

Here is the relevant code:

$uploaded = 0;
	$messages = array();
	if(isset($_FILES['uploadFiles']['name'])) {
		foreach ($_FILES['uploadFiles']['name'] as $i => $name) {
			if ($_FILES['uploadFiles']['error'][$i] == 4) {
				continue; 
			}
			if ($_FILES['uploadFiles']['error'][$i] == 0) {

				if ($_FILES['uploadFiles']['size'][$i] > 99439443) {
					$messages[] = "$name exceeded file limit.";
					continue;  
				}				

				$uploaded++;
			}
		}
		$files = $_FILES['uploadFiles']['tmp_name'];
	}
	echo "$uploaded receipt";
	if($uploaded != 1) {
		echo "s";
	}
	echo " uploaded.";

	foreach ($messages as $error) {
		echo $error;
	}

	// boundary 
	$semi_rand = md5(time()); 
	$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 

	// headers for attachment
	$eol = PHP_EOL;
	$headers = "From: ".$to.$eol;
	$headers .= "Reply-To: ".$to.$eol;
	$subject = "Expense Report - Period Ending $reportDate";
	$headers .= "MIME-Version: 1.0".$eol; 
	$headers .= "Content-Type: multipart/mixed; boundary=\"".$mime_boundary."\"".$eol.$eol;


	// no more headers after this, we start the body! //

	//$body = "--".$mime_boundary.$eol;
	//$body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
	$body .= "This is a multi-part message in MIME format.".$eol;

	// message
	$body .= "--".$mime_boundary.$eol;
	$body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
	$body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
	$body .= $message.$eol.$eol;

	if($uploaded > 0) {  // if there are attachments add this line to the message, otherwise with no attachments this line will add an unwanted attachment
		//$message .= "--{$mime_boundary}\n";
	}


	if(isset($_FILES['uploadFiles']['name'])) {
		// preparing attachments
		for($x=0;$x<count($files);$x++){
			$file = fopen($files[$x],"rb");
			$data = fread($file,filesize($files[$x]));
			fclose($file);
			$data = chunk_split(base64_encode($data));
			$name = $_FILES['uploadFiles']['name'][$x];
			/*$body .= "–{$mime_boundary}\n";
			$body .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$name\"\n" . 
			"Content-Disposition: attachment;\n" . " filename=\"$name\"\n" . 
			"Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
			//$body .="--{$mime_boundary}--\n";
			if ($x==count($files)-1) {
				//$message .="--{$mime_boundary}-\n";
			}
			else{
				//$message .="--{$mime_boundary}\n";
			}*/
			// attachment
			$body .= "--".$mime_boundary.$eol;
			$body .= "Content-Type: application/octet-stream; name=\"".$name."\"".$eol; 
			$body .= "Content-Transfer-Encoding: base64".$eol;
			$body .= "Content-Disposition: attachment".$eol.$eol;
			$body .= $data.$eol.$eol;
			$body .= "--".$mime_boundary."--";

		}
	}

	// send

	$ok = @mail($to, $subject, $body, $headers); 
	if ($ok) { 
		echo "<p>email sent to $to!</p>"; 
		} else { 
		echo "<p>email could not be sent!</p>"; 
	}
}
?>

Do I have to move the uploaded file to a permanent location or can I just use the 'tmp_name' to email it?

Heh, figured this one out on my own.  Turns out for my situation, I had to do a "move_uploaded_file" to a folder in my web root for it to work.  Maybe this isn't always the case, but it fixed my problem.  I also had to move the last "$body .= "--".$mime_boundary."--";" outside of the for loop to get it to work with multiple files.  Maybe this will help someone else out.
