PHP - JPath Moving Multiple files to correct directory - php

Question

See my last question as this links to it: PHP - Moving multiple files with different files names to own directory
So i decided to using the Joomla API however, the documentation was for 1.5 and 2.5 system only but i'm using 3.0. I have a number of files that look like this:
"2005532-JoePharnel.pdf"
and
"1205121-HarryCollins.pdf"
Basically I want to create a PHP code that when someone ftp uploads those files to the upload folder that it will 1) Create a directory if it doesn't exist using there name 2) Move the files to the correct directory (E.g. JoePharnel to the JoePharnel Directory ignoring the number at the beginning)
Updated: 23/10/14 - 14:05:
My new code creates the folder but won't move the file in the upload into that new folder, code is below:
<?php
define( '_JEXEC', 1);
define('JPATH', dirname(__FILE__) );
if (!defined('DS')){
define( 'DS', DIRECTORY_SEPARATOR );
$parts = explode( DS, JPATH );
$script_root = implode( DS, $parts ) ;
// check path
$x = array_search ( 'administrator', $parts );
if (!$x) exit;
$path = '';
for ($i=0; $i < $x; $i++){
$path = $path.$parts[$i].DS;
}
// remove last DS
$path = substr($path, 0, -1);
if (!defined('JPATH_BASE')){
define('JPATH_BASE', $path );
}
if (!defined('JPATH_SITE')){
define('JPATH_SITE', $path );
}
/* Required Files */
require_once ( JPATH_SITE . DS . 'includes' . DS . 'defines.php' );
require_once ( JPATH_SITE . DS . 'includes' . DS . 'framework.php' );
require_once ( JPATH_SITE . DS . 'libraries' . DS . 'joomla' . DS . 'factory.php' );
//Import filesystem libraries. Perhaps not necessary, but does not hurt
jimport('joomla.filesystem.path');
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.folder');
jimport('joomla.user.user');
//First we set up parameters
$searchpath = JPATH_BASE . DS . "upload";
//Then we create the subfolder called png
if ( !JFolder::create($searchpath . DS ."Images") ) {
//Throw error message and stop script
}
//Now we read all png files and put them in an array.
$png_files = JFolder::files($searchpath,'.png');
//Now we need some stuff from the JFile:: class to move all files into the new folder
foreach ($png_files as $file) {
JFile::move($searchpath. DS . ".png" . $file, $searchpath . DS. "Images" . $file);
}
//Lastly, we are moving the complete subdir to the root of the component.
if (JFolder::move($searchpath . DS. "Images",JPATH_COMPONENT) ) {
//Redirect with perhaps a happy message
} else {
//Throw an error
}
}
?>
Only error i get is Notice: Use of undefined constant JPATH_COMPONENT - assumed 'JPATH_COMPONENT' in /upload.php on line 70. But doesn't stop it working, am so close on this any help is greatly appreciated. I want to know where its taking the image, i think i have worked out the "DS" now.
Thanks
