Hi guys

I have created these codes below,

uploadform.php

<html>
<head>
</head>

<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<table>
        <tr>
		<td><div align="left">Submit photo </div></td>
		<td><div align="left">
			<input type="file" name="file" id="file" />						
		</div></td>
        </tr>
        <tr>
		<td><div align="left"></div></td>
		<td><div align="left">
			<input type="submit" name="Submit" value="Submit" />
		</div></td>
        </tr>
</table>
</form>
</body>
</html>

upload.php

<?php
/************************
* Upload file
*************************/
if (isset($_POST['Submit'])) { //if "email" is filled out, send email
/*** Upload File ***/
if($_FILES["file"]["size"] < 20000)
{
	if ($_FILES["file"]["error"] > 0)
	{
		echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
	}
	else
	{
	//echo "Upload: " . $_FILES["file"]["name"] . "<br />";
	//echo "Type: " . $_FILES["file"]["type"] . "<br />";
	//echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
	//echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

	if (file_exists("upload/" . $_FILES["file"]["name"]))
	  {
	  //$_FILES["file"]["name"]
	  // Do nothing...
	  }
	else
	  {
	  move_uploaded_file($_FILES["file"]["tmp_name"],
	  "upload/" . $_FILES["file"]["name"]);
	  $url = "http://asiamodeltalent.com/php/mt/" . "upload/" . $_FILES["file"]["name"];
	  }
	}
}
else
{
	echo "Invalid file";
}

/************************
* Insert path and filename to array

$fname = $_FILES["file"]["name"];
$files = array("$fname");


/************************

*************************/	

$to = "[email protected]";
$from = "[email protected]"; 
$subject ="Email File"; 
$message = "Test email with file attached.\n";
$headers = "From: $from";

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

// headers for attachment 
$headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; 

// multipart boundary 
$message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; 
$message .= "--{$mime_boundary}\n";

// preparing attachments
$pathupload = "http://coder9.com/php/mt/" . "upload/";	
for($x=0;$x<count($files);$x++){
	//$file = fopen($files[$x],"rb");
		$file = fopen($url[$x], "rb");				
	//$data = fread($file,filesize($files[$x]));
		$data = fread($file, filesize($url[$x]));
	fclose($file);
	$data = chunk_split(base64_encode($data));
	$message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . 
	"Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
	"Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
	$message .= "--{$mime_boundary}\n";
}

// send

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


}
?>

The problem with this codes is the file is attached but it's empty.

By the way if you want to test it you need a sub directory of /upload

What is the cause of this problem?

Thanks in advanced.
