Como imprimir o nome do arquivo enviado

[csilva]

Olá, amigos.

Alguém poderia me ajudar? Tenho esse arquivo de upload e não consigo imprimor o nome do arquivo ($filename). Nos meus esforços, de quem é iniciante em PHP, somente congui o arquivo tmp ($tmpFile). O script envia arquivos para o Dropbox. Obrigado.

<?php

$passw = "xxxxxxx"; //change this to a password of your choice.

if ($_POST) {

require 'DropboxUploader.php';

try {

// Rename uploaded file to reflect original name

if ($_FILES['file']['error'] !== UPLOAD_ERR_OK)

throw new Exception('File was not successfully uploaded from your computer.');

$tmpDir = uniqid('/tmp/DropboxUploader-');

if (!mkdir($tmpDir))

throw new Exception('Cannot create temporary directory!');

if ($_FILES['file']['name'] === "")

throw new Exception('File name not supplied by the browser.');

$tmpFile = $tmpDir.'/'.str_replace("/", '_', $_FILES['file']['name']);

if (!move_uploaded_file($_FILES['file']['tmp_name'], $tmpFile))

throw new Exception('Cannot rename uploaded file!');

if ($_POST['txtPassword'] != $passw)

throw new Exception('Wrong Password');

// Upload

$uploader = new DropboxUploader(xxx@xxx.net, 'xxxxxx');// enter dropbox credentials

$uploader->upload($tmpFile, $_POST['dest']);

echo '<span style="color: green;font-weight:bold;margin-left:393px;">Enviado com sucesso!</span>';

} catch(Exception $e) {

echo '<span style="color: red;font-weight:bold;margin-left:393px;">Error: ' . htmlspecialchars($e->getMessage()) . '</span>';

}

// Clean up

if (isset($tmpFile) && file_exists($tmpFile))

unlink($tmpFile);

if (isset($tmpDir) && file_exists($tmpDir))

rmdir($tmpDir);

}

?>

<form method="post" action="" enctype="multipart/form-data">

<input type="file" name="file" /><br><br>

<input type="submit" value="Upload the file to my Dropbox!" />

<input style="display:none" type="text" name="dest" value="sua pasta de destino" />

<br/>

<br/>

Password: <input type="password" title="Enter your password" name="txtPassword" />

</form>
