Joomla JFile and JFolder - PHP

[simpsonnth]

Hi there,

I have decided 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:

"14-05-14 JoePharnel.pdf"

and

"13-05-12 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)

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. 

I have used and adapted multiple php code so any help would be appreciated. Or if you can point me to where i can find the answer that would be brilliant
