How to get my zend script picture filename into a hidden field - zend-framework

Question

OK, I am stumped here. I'm using a Zend script that helps me to upload pictures. It works great, but I am trying to capture the pictures name into a hidden field for a form. I'd like to note that the name changes, so I'd need to get whichever it ends up being put into the hidden field. Here is the Zend script:
<?php
if (isset($_POST['upload'])) {
require_once('scripts/library.php');
try {
$destination = 'xxxxxxxx';
$uploader = new Zend_File_Transfer_Adapter_Http();
$uploader->setDestination($destination);
$filename = $uploader->getFileName(NULL, FALSE);
$uploader->addValidator('Size', FALSE, '90kB');
$uploader->addValidator('ImageSize', FALSE, array('minheight' => 100, 'minwidth' => 100));
if (!$uploader->isValid()) {
$messages = $uploader->getMessages();
} else {
$no_spaces = str_replace(' ', '_', $filename, $renamed);
$uploader->addValidator('Extension', FALSE, 'gif, png, jpg');
$recognized = FALSE;
if ($uploader->isValid()) {
$recognized = TRUE;
} else {
$mime = $uploader->getMimeType();
$acceptable = array('jpg' => 'image/jpeg',
'png' => 'image/png',
'gif' => 'image/gif');
$key = array_search($mime, $acceptable);
if (!$key) {
$messages[] = 'Unrecognized image type';
} else {
$no_spaces = "$no_spaces.$key";
$recognized = TRUE;
$renamed = TRUE;
}
}
$uploader->clearValidators();
if ($recognized) {
$existing = scandir($destination);
if (in_array($no_spaces, $existing)) {
$dot = strrpos($no_spaces, '.');
$base = substr($no_spaces, 0, $dot);
$extension = substr($no_spaces, $dot);
$i = 1;
do {
$no_spaces = $base . '_' . $i++ . $extension;
} while (in_array($no_spaces, $existing));
$renamed = TRUE;
}
$uploader->addFilter('Rename', array('target' => $no_spaces));
$success = $uploader->receive();
if (!$success) {
$messages = $uploader->getMessages();
} else {
$uploaded = "$filename uploaded successfully";
$pic = $filename;
if ($renamed) {
$uploaded .= " and renamed $no_spaces";
}
$messages[] = "$uploaded";
}
}
}
} catch (Exception $e) {
echo $e->getMessage();
}
}
Here I am trying to make the $pic variable not to throw an error for now (on the form page)
if (isset($_POST['upload'])) { } else { $pic = "unknown";}
The $pic variable is what I was trying to have the filename from the zend script copied into. Any feedback is greaaaatly appreciated :)
