[SOLVED] Getting parent url codeigniter

[eluser]riwakawd[/eluser]
After thinking about it for a while I had to do this working great now.

Code:

if (isset($_SERVER['HTTP_HOST'])) {

$catalog_url = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on' ? 'https' : 'http';    
$catalog_url .= '://'. $_SERVER['HTTP_HOST'] . rtrim(rtrim(dirname($_SERVER['SCRIPT_NAME']), 'admin'), '/.\\'). '/';

} else {

// Back Up Url
$base_url = 'http://localhost/';

}

define('CATALOG_URL', $catalog_url);

unset($catalog_url);
