How to get user session info from external php script with Joomla 4?

[amer1404]

How we can get the logged-in user information and session information from the external php script with Joomla-4.x?

The below code works with Joomla 3.x but doesn't work with Joomla-4.x

==================================================================
define( '_JEXEC', 1 );
define( 'JPATH_BASE', realpath(dirname(__FILE__).'/../..' ));
require_once ( JPATH_BASE .'/includes/defines.php' );
require_once ( JPATH_BASE .'/includes/framework.php' );
$mainframe = JFactory::getApplication('site');
$mainframe->initialise();
$session = JFactory::getSession();
jimport( 'joomla.application.module.helper' );

$session = $session->getId();
$db = JFactory::getDbo();
$user =& JFactory::getUser();
$userid= $user->id;
===================================================================

An idea to try:

From the command line, cd to the cli folder of your site and type:

php joomla.php user:list

You get a list of all registered users. This is not what you want but maybe you can create something similar to fetch only logged in users, such as in the Who's online module. Use php joomla.php to get a list of all available commands.

Thanks, Dear @ceford

Actually, I need to get the user session from the PHP script not command line in order to handle data from/to the database using the JFactory package

e.g :

Code: Select all

<?php
define( '_JEXEC', 1 );
define( 'JPATH_BASE', realpath(dirname(__FILE__).'/../..' ));
require_once ( JPATH_BASE .'/includes/defines.php' );
require_once ( JPATH_BASE .'/includes/framework.php' );
$mainframe = JFactory::getApplication('site');
$mainframe->initialise();
$session = JFactory::getSession();
jimport( 'joomla.application.module.helper' );

$session_id = $session->getId();
$db = JFactory::getDbo();
$user =& JFactory::getUser();
$user_id= $user->id;

if ($session_id != NULL && $user_id != NULL){


$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select($db->quoteName(array('student_id', 'student_name')));
$query->from($db->quoteName('#__student'));
$db->setQuery($query);

$db->execute();
$total_records = $db->getNumRows();
$result = $db->loadRowList();
//......
//..........
//..............etc

}
else { echo"invalid request";}
?>

I'm assuming you're running the server script from a client browser, and assuming that the user has previously logged onto the site. If so, this code worked for me:

Code: Select all

<?php

use Joomla\CMS\Factory;
use Joomla\CMS\Session\Session;

error_reporting(E_ALL);
ini_set('display_errors', 1);

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

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

// Boot the DI container
$container = \Joomla\CMS\Factory::getContainer();

/*
 * Alias the session service keys to the web session service as that is the primary session backend for this application
 *
 * In addition to aliasing "common" service keys, we also create aliases for the PHP classes to ensure autowiring objects
 * is supported.  This includes aliases for aliased class names, and the keys for aliased class names should be considered
 * deprecated to be removed when the class name alias is removed as well.
 */
$container->alias('session.web', 'session.web.site')
    ->alias('session', 'session.web.site')
    ->alias('JSession', 'session.web.site')
    ->alias(\Joomla\CMS\Session\Session::class, 'session.web.site')
    ->alias(\Joomla\Session\Session::class, 'session.web.site')
    ->alias(\Joomla\Session\SessionInterface::class, 'session.web.site');

// Instantiate the application.
$app = $container->get(\Joomla\CMS\Application\SiteApplication::class);

// Set the application as global app
\Joomla\CMS\Factory::$application = $app;

$user = \Joomla\CMS\Factory::getApplication()->getSession()->get('user');

if ($user && $user->id > 0){
    // do query

} else {
    echo "not logged on\n";
}

Thank dear robbiej for your help!
I really appreciate your input. The code you provided makes sense, and I'll give it a try. It's great to have your guidance as I work on this. Thanks again!
