The next function need a variable instead of explode direct.

public function attach($filename, $name = FALSE)
{
if (!file_exists($filename)) return FALSE;
if ( ! $name) $name = basename($filename);

$ext=explode('.', basename($filename));
$ext=count($ext)>1 ? $ext[1] : "";

$this->attach[] = array( "filename" 	=> $filename,
								"mime_type"	=> $this->_mime_types($ext),
								"name"		=> $name,
								"ext"			=> $ext,
					);
return $this;
}
