include Jfactory class in an external php file, Joomla

Question

I am writing a module for Joomla, at this point I really need to be able to connect to the database using Jfactory. Normally one could simply use $db = JFactory::getDB

Answer 1

Recently, the libraries/joomla/factory.php has been removed, which was causing all the scripts that utilized require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' ); to fail. As this is still used in the accepted & most upvoted answer here, it's time to an update...

You don't need the JDatabaseFactory class anymore to use Joomla database functions through JFactory::getDBO(); as the JFactory class provides them and gets already included.

These five lines are enough:

define('_JEXEC', 1);
define('JPATH_BASE', dirname(__FILE__));
define('DS', DIRECTORY_SEPARATOR);
require_once JPATH_BASE.DS.'includes'.DS.'defines.php';
require_once JPATH_BASE.DS.'includes'.DS.'framework.php';

You will be able to do e.g. this again:

$db =& JFactory::getDBO();
$query = "SELECT ...";
$db->setQuery($query);
$db->query();

I'm sure that you figure it out, but maybe it would be useful for someone else

To use joomla database class (even if you know that is not recommended :) ) you need, first to define three constants, like:

define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE', $_SERVER[ 'DOCUMENT_ROOT' ] );

Then you need to include three files, like:

require_once( JPATH_BASE . DS . 'includes' . DS . 'defines.php' );
require_once( JPATH_BASE . DS . 'includes' . DS . 'framework.php' );
require_once( JPATH_BASE . DS . 'libraries' . DS . 'joomla' . DS . 'factory.php' );
$mainframe =& JFactory::getApplication('site');

EDIT

You can include only two files like:

define( 'JPATH_BASE', $_SERVER[ 'DOCUMENT_ROOT' ] ); // define JPATH_BASE on the external file
require_once( JPATH_BASE . DS . 'libraries' . DS . 'import.php' ); // framework
require_once( JPATH_BASE . DS . 'configuration.php' ); // config file

Finally use joomla class, like:

$db = JFactory::getDBO();

For accessing Database information of Joomla ,You should include("configuration.php").This joomla configuaraion file contains all information of database access.

class JFactory defined in this folder "joomlaRootFolder/libraries/joomla/factory.php"
