How to use JFactory::getLanguage() from another directory?

Question

How can I get the current selected language using the Function JFactory::getLanguage(); from another directory?

I know how to do it when I am there:

• /web/include
• /web <---- [can call it from here] (solved here)

but I need to call it from...

• /web/scripts/myScripts/myScript.php

Tried to import Joomla Framework:

// Set flag that this is a parent file.
define('_JEXEC', 1);
define('DS', DIRECTORY_SEPARATOR);

if (file_exists(dirname(__FILE__) . '/../../defines.php')) {
    include_once dirname(__FILE__) . '/../../defines.php';
}

if (!defined('_JDEFINES')) {
    define('JPATH_BASE', dirname(__FILE__));
    require_once JPATH_BASE.'/../../includes/defines.php';
}
require_once JPATH_BASE.'/../../includes/framework.php';

// Instantiate the application.
$app = JFactory::getApplication('site');

// Initialise the application.
$app->initialise();

$lang =& JFactory::getLanguage()->getTag();

The definition for JPATH_BASE is still missing from your code. To import the Joomla API, you can simply use the following:

define( '_JEXEC', 1 );
define( 'JPATH_BASE', realpath(dirname(__FILE__).'/..' ));

require_once ( JPATH_BASE . '/includes/defines.php' );
require_once ( JPATH_BASE . '/includes/framework.php' );

$app = JFactory::getApplication('site');
$app->initialise();

Then to get the language tag:

$lang = JFactory::getLanguage();
$tag  = $lang->getTag();

You need to make sure JPATH_BASE has been defined correctly. I'm not sure where your external PHP file is located in relation to your Joomla installation, but you will need to change line 2 of the API importing code.

Hope this helps
