Howto access joomla session variables from another php script

March 11, 2010 12 comments

Here is an example of how to access joomla session data from another php script.
This is particular useful for implementing an AMF gateway or other ajax functionality.

To access the Joomla! session variables from another script, the easiest way is to instantiate the joomla application in that script. Please note that this will only work if that script is not already using its own session.

Example Code:

define( '_JEXEC', 1 ); define( 'DS', DIRECTORY_SEPARATOR ); define('JPATH_BASE', dirname(__FILE__) );

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

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

$session =& JFactory::getSession(); $user = $session->get( 'user' );

In this example I’m assuming the script is located in the main joomla directory.
If the script sits in some subdirectory you’ll have to adjust the JPATH_BASE definition.

Hi rishabh – which file is being referenced at line 24 in your survey.php script?

This is just awesome..!! Actually i am fetching some data through ajax file and this data has to be come only for registered users. I thought matching of session id’s but ajax file session id is totally different from the joomla site session id. But when i use above code in my ajax file it i found ajax file sessionid id is same as my joomla site session id… it works like a butter..

Thanks a ton to share extremely helpful information!!

I was able to adjust the path from a module to defines.php and framework.php with:
require_once ( “..”.DS.”..”.DS.’includes’.DS.’defines.php’ );
require_once ( “..”.DS.”..”.DS.’includes’.DS.’framework.php’ );

However now I am getting:
No configuration file found and no installation code available. Exiting…

you would have to set you JPATH_BASE definition right rather then adjusting the require_once statements

This helped a lot, I used several hours on this before i found your code…
Based on your code I’m now able to get an Community Builder field from another script.

Here is my code if this can help anybody trying to do the same:
( My script is in an underdirectory, hence JPATH_BASE = ../ )

define( ‘_JEXEC’, 1 );
define( ‘DS’, DIRECTORY_SEPARATOR );
//define(‘JPATH_BASE’, dirname(__FILE__) );
define(‘JPATH_BASE’, “../”);

require_once ( JPATH_BASE .DS.’includes’.DS.’defines.php’ );
require_once ( JPATH_BASE .DS.’includes’.DS.’framework.php’ );

$mainframe =& JFactory::getApplication(‘site’);
$mainframe->initialise();

$session =& JFactory::getSession();
$user = $session->get( ‘user’ );

global $_CB_framework, $mainframe;

if ( defined( ‘JPATH_ADMINISTRATOR’ ) ) {
if ( ! file_exists( JPATH_ADMINISTRATOR . ‘/components/com_comprofiler/plugin.foundation.php’ ) ) {
echo ‘CB not installed!’;
return;
}

include_once( JPATH_ADMINISTRATOR . ‘/components/com_comprofiler/plugin.foundation.php’ );
} else {
if ( ! file_exists( $mainframe->getCfg( ‘absolute_path’ ) . ‘/administrator/components/com_comprofiler/plugin.foundation.php’ ) ) {
echo ‘CB not installed!’;
return;
}

include_once( $mainframe->getCfg( ‘absolute_path’ ) . ‘/administrator/components/com_comprofiler/plugin.foundation.php’ );
}

cbimport( ‘cb.database’ );
cbimport( ‘language.front’ );
cbimport( ‘cb.snoopy’ );
cbimport( ‘cb.imgtoolbox’ );
cbimport( ‘cb.html’ );
cbimport( ‘cb.plugins’ );

$cbUser =& CBuser::getInstance( $user->id );

if ( ! $cbUser ) {
$cbUser =& CBuser::getInstance( null );
}

$teamID = $cbUser->getField( ‘cb_teamid’, null, ‘html’, ‘none’, ‘list’ );
//echo “teamID: “.$teamID;
