    Here's a good multi-upload script I'm using :
    

// make a note of the current working directory relative to root.
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);

// make a note of the location of the upload handler
$uploadHandler = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'your_uploadhandler.php';

// set a max file size for the html upload form
$max_file_size = 300000; // size in bytes

// make a note of the directory that will recieve the uploaded files
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploads/';

// make a note of the location of the upload form in case we need it
$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload_form.php'; // can be the same file

// make a note of the location of the success page
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'success.php';  // can be the same file

// name of the fieldname used for the file in the HTML form
$fieldname = 'file';

// Now let's deal with the uploaded files

// possible PHP upload errors
$errors = array(1 => 'php.ini max file size exceeded',
                2 => 'html form max file size exceeded',
                3 => 'file upload was only partial',
                4 => 'no file was attached');

// check the upload form was actually submitted else print form
isset($_POST['add'])
    or error('the upload form is needed', $uploadForm);
    
// check if any files were uploaded and if
// so store the active $_FILES array keys
$active_keys = array();
foreach($_FILES[$fieldname]['name'] as $key => $filename)
{
    if(!empty($filename))
    {
        $active_keys[] = $key;
    }
}

// check at least one file was uploaded
count($active_keys)
    or error('No files were uploaded', $uploadForm);
        
// check for standard uploading errors
foreach($active_keys as $key)
{
    ($_FILES[$fieldname]['error'][$key] == 0)
        or error($_FILES[$fieldname]['tmp_name'][$key].': '.$errors[$_FILES[$fieldname]['error'][$key]], $uploadForm);
}
    
// check that the file we are working on really was an HTTP upload
foreach($active_keys as $key)
{
    @is_uploaded_file($_FILES[$fieldname]['tmp_name'][$key])
        or error($_FILES[$fieldname]['tmp_name'][$key].' not an HTTP upload', $uploadForm);
}
    
// validation... since this is an image upload script we
// should run a check to make sure the upload is an image
foreach($active_keys as $key)
{
    @getimagesize($_FILES[$fieldname]['tmp_name'][$key])
        or error($_FILES[$fieldname]['tmp_name'][$key].' not an image', $uploadForm);
}
    
// make a unique filename for the uploaded file and check it is
// not taken... if it is keep trying until we find a vacant one
	$uploadFilename[$key] = $uploadsDirectory.$_FILES[$fieldname]['name'][$key];

$nameArr = explode("/",$uploadFilename[$key]);
$newname = $nameArr[sizeof($nameArr_1)-2]."/".$nameArr_1[sizeof($nameArr_1)-1]; 

// now let's move the file to its final and allocate it with the new filename
foreach($active_keys as $key)
{
    @move_uploaded_file($_FILES[$fieldname]['tmp_name'][$key], $uploadFilename[$key])
        or error('receiving directory insuffiecient permission', $uploadForm);
}
    
// If you got this far, everything has worked and the file has been successfully saved.
// We are now going to redirect the client to the success page.
header('Location: ' . $uploadSuccess);

// make an error handler which will be used if the upload fails
function error($error, $location, $seconds = 5)
{
    header("Refresh: $seconds; URL=\"$location\"");
    echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'."\n".
    '"http://www.w3.org/TR/html4/strict.dtd">'."\n\n".
    '<html lang="en">'."\n".
    '    <head>'."\n".
    '        <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">'."\n\n".
    '        <link rel="stylesheet" type="text/css" href="stylesheet.css">'."\n\n".
    '    <title>Upload error</title>'."\n\n".
    '    </head>'."\n\n".
    '    <body>'."\n\n".
    '    <div id="Upload">'."\n\n".
    '        <h1>Upload failure</h1>'."\n\n".
    '        <p>An error has occured: '."\n\n".
    '        <span class="red">' . $error . '...</span>'."\n\n".
    '         The upload form is reloading</p>'."\n\n".
    '     </div>'."\n\n".
    '</html>';
    exit;
} // end error handler

// redirect to current page so if we click the refresh button
// the form won't be resubmitted ( as that would make duplicate entries )
header('Location: ' . $_SERVER['REQUEST_URI']);

exit;
}
ob_end_flush();

// YOUR UPLOAD FORM SHOULD GO HERE something like :

    <form id="Upload" action="<?php echo $uploadHandler ?>" enctype="multipart/form-data" method="post">

    <p>
    <input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max_file_size ?>">
    </p>

// ETC......
    PHP:
    It's doing great job for me!

    Thanks! that is pretty sweet. Its not exactly what i'm looking for but it will come in handy.

    I basically need a function that will look at a directory recursively take note of all the files and directories within and then upload them to a specified location via ftp..

    I see.
    No problem, that can be done too. Use this script to 'read' all the files within a directory :

    
if (is_dir($target_dir)) {
if ($dh = opendir($target_dir)) {
while (($file = readdir($dh)) !== false) {

if (filetype($target_dir . "/" . $file) == "file")
echo $file " - " .
round(filesize($target_dir . "/" . $file)/1024) . "K " . date
("m/d/Y H:i:s", filemtime($target_dir . "/" . $file)) ;
}
closedir($dh);
}
}
    PHP:
    Combine it with this script to upload your files :
    
// FTP access parameters
$host = 'ftp.example.org';
$usr = 'example_user';
$pwd = 'example_password';
 
// file to move:
$local_file = './example.txt';
$ftp_path = '/data/example.txt';
 
// connect to FTP server (port 21)
$conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");
 
// send access parameters
ftp_login($conn_id, $usr, $pwd) or die("Cannot login");
 
// turn on passive mode transfers (some servers need this)
// ftp_pasv ($conn_id, true);
 
// perform file upload
$upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);
 
// check upload status:
print (!$upload) ? 'Cannot upload' : 'Upload complete';
print "\n";

// close the FTP stream
ftp_close($conn_id);
    PHP:
    Hope this might help...

    One small notice you should probably consider, Mozilla uses "none" to indicate an empty upload field
    
$_FILES['form_field']['name'] == "none";
