Problem creating folder and uploading files.

Why not use the fileupload library that comes with CodeIgniter?

PHP Code:

$config['upload_path'] = $pathToUpload . '/';
$config['allowed_types'] = '*';
$config['overwrite'] = TRUE;
$this->load->library('upload',$config);
$this->upload->do_upload(); 


The do_upload method does all the work. It detects files that are in $_FILES.
