Is it possible to load parameters from a disabled Joomla module in an external PHP file?
$module = &JModuleHelper::getModule('example'); //Get the module (in this case "example")
$moduleParams = new JParameter($module->params); //Retrieve this modules parameters
$param = $moduleParams->get('paramName', 'defaultValue'); //Get the specific parameter
This code should retrieve the article parameters whether disabled or not. If it's an external php file in terms of being outside of Joomla you'll also need to load the Joomla classes using:
//init Joomla Framework
define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE', realpath(dirname(__FILE__).DS.'..'.DS.'..'.DS.'..'));
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
$mainframe = JFactory::getApplication('site');

in my joomla 1.5 password hash by md5+salt, they look like this:
6e3bb23b32702ee94ebc18e2a059fe4a:wxIZ6BNkAFpQk4ggeRvoOIrgbWerif0x
but on joomla 2.5 it is:
$P$DTJoqPcMQgUhl6cPrzzBOTFIFHQaNf1
HOW can i change hash algorithm in joomla 2.5?
Try this,
The older algorithm will works fine with 2.5 , only the length is changed
The New code is :
<?php
jimport('joomla.user.helper');
$password = "test";
JUserHelper::hashPassword($password);
?>
Older Version Code:
jimport('joomla.user.helper');
$salt = JUserHelper::genRandomPassword(32);
$crypt = JUserHelper::getCryptedPassword($password_choose, $salt);
$password = $crypt.':'.$salt;
When you are working with external php script load the Joomla library to that file,
define( '_JEXEC', 1 );
define('JPATH_BASE', dirname(__FILE__) );//this is when we are in the root
define( 'DS', DIRECTORY_SEPARATOR );
require_once( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once( JPATH_BASE .DS.'includes'.DS.'framework.php' );
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
Hope it make sense..
I am developing small web application(mobile), based on Joomla component. Is it possible to use methods from specific component in custom files? For example now to use core functions such as database i am using something like:
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');
$mainframe = &JFactory::getApplication('site');
$mainframe->initialise();
$this->db = &JFactory::getDbo();
Try using 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' );
require_once ( JPATH_BASE .'/libraries/joomla/factory.php' );
$db = JFactory::getDbo();
is it possible to render Joomla content from external script? For example I have some html string, which I want to pass to com_content component, to make all content plugin and module features available. I think I should use JDocumentRendererComponent class. Code in my external file:
<?php
require_once ('framework.php'); //loading joomla framework
jimport('joomla.document.html.renderer.component');
$contentHtml = '<p>Some content html</p>';
echo JDocumentRendererComponent::render('com_content',array(),$contentHtml);
?>
What I get is error on the last line:
Fatal error: Class 'JDocumentRendererComponent' not found...
What Im doing wrong? Any ideas?
It's because you haven't included the Joomla framework to the external script. Use the below code. This will ensure that the Joomla! environment is loaded correctly
/* Initialize Joomla framework */
define( '_JEXEC', 1 );
define('JPATH_BASE', dirname(__FILE__) );
define( 'DS', DIRECTORY_SEPARATOR );
/* Required Files */
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
/* To use Joomla's Database Class */
require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' );
/**************************************************/
// Your code starts here...
// Remember that the Site application isn't running, so you cannot access $mainframe or any of its methods.
/**************************************************/
JDocumentRendererComponent Class is located in located in /libraries/joomla/document/html/renderer/component.php if you correct load the framework everything should work fine.
I found other solution for my question. The job can be also done by content plugin events (triggers). The piece of code from components/com_content/views/article/view.html.php:
JPluginHelper::importPlugin('content');
$results = $dispatcher->trigger('onContentPrepare', array ('com_content.article', &$item, &$this->params, $offset));
$item->event = new stdClass();
$results = $dispatcher->trigger('onContentAfterTitle', array('com_content.article', &$item, &$this->params, $offset));
$item->event->afterDisplayTitle = trim(implode("\n", $results));
$results = $dispatcher->trigger('onContentBeforeDisplay', array('com_content.article', &$item, &$this->params, $offset));
$item->event->beforeDisplayContent = trim(implode("\n", $results));
$results = $dispatcher->trigger('onContentAfterDisplay', array('com_content.article', &$item, &$this->params, $offset));
$item->event->afterDisplayContent = trim(implode("\n", $results));
So we can actually make an object from our string and pass it to these triggers. As a result we are getting content rendered like an article, with its major functionality.

I'm trying to get session variables working with Joomla using their session code since php's sessions don't work. I am running into a problem trying to access session variables within the joomla custom code module editor though. When I try to access the session variable using the code:
define( '_JEXEC', 1 );
define('JPATH_BASE', "../");
define( 'DS', DIRECTORY_SEPARATOR );
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' );
$session = JFactory::getSession();
$print $session->get('status');
I get nothing. If I take that same code and paste it into its own php file I can get the status variable fine. When I look at the plain text version of Joomla preview I see this:
get('status'); ?>
Doing some testing I think it's related to the '->' operand. Has anyone encountered this before and know how to fix it? I'm running Direct PHP and can print out strings and other variables inside of the module fwiw.
you can't run PHP (or Javascript!) in Joomla articles without installing a plugin that supports it. I recommend using: http://www.kksou.com/php-gtk2/Joomla/DirectPHP-plugin.php
change $print to print
Try to comment out all the preceding lines and see if one of the "includes" is messing up the page:
/*define( '_JEXEC', 1 );
define('JPATH_BASE', "../");
define( 'DS', DIRECTORY_SEPARATOR );
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' );
*/
$session = JFactory::getSession();
print $session->get('status');
I need to get the information of the user that's currently logged in to Joomla from a program outside of Joomla itself. I upgraded from 1.5 to 2.5, and what I had before doesn't work anymore.
<?php
define( '_VALID_MOS', 1 );
include_once( 'globals.php' );
require_once( 'configuration.php' );
require_once( 'includes/joomla.php' );
$option="test";
$mainframe = new mosMainFrame( $database, $option, '.' );
$mainframe->initSession();
$my = $mainframe->getUser();
$joomla_name = $my->name;
$joomla_email = $my->email;
$joomla_password = $my->password;
After some research, I've come up with this:
<?php
define( '_JEXEC', 1 );
define( 'JPATH_BASE', dirname(__FILE__) );
define( 'DS', '/' );
require_once ( JPATH_BASE .DS.'configuration.php' );
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' );
$my =& JFactory::getUser();
$joomla_name = $my->name;
$joomla_email = $my->email;
$joomla_password = $my->password;
$joomla_username = $my->username;
It doesn't produce any errors but seems to work. However, the user object is empty. This script is in the same directory as the Joomla installation. What may be the problem? Thanks!

Solution: Replace session_start(); in your external script with
define( '_JEXEC', 1 );
define( 'JPATH_BASE', realpath(dirname(__FILE__).'/../..' ));
define( 'DS', DIRECTORY_SEPARATOR );
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();
Be sure to change JPATH_BASE to suit your directory structure.
Replace the $_SESSION[ 'name' ] = "value"; in your external script with
$session =& JFactory::getSession();
$session->set('name', "value");
Now you can retrieve this session variable using:
$session =& JFactory::getSession();
echo $session->get('name');
It turns out, I had two problems:
My script was on www.example.com, while I was logged in under example.com, so the different domain was throwing off the session data.
I also wasn't initialising the application, which apparently is necessary.
Here are the results:
<?php
define( '_JEXEC', 1 );
define( 'JPATH_BASE', dirname(__FILE__) );
define( 'DS', '/' );
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
JFactory::getApplication('site')->initialise();
$user = JFactory::getUser();
$joomla_name = $user->name;
$joomla_email = $user->email;
$joomla_password = $user->password;
$joomla_username = $user->username;
I think people have had problems with this in Joomla 2.5 as things have changed. I haven't found a solution for the way you have requested but wrote this work around (excluding the password field though) that you may want to use.
define a connection to the database:
<?php
$host="localhost";
$username="DB_USERNAME";
$password="DB_PASSWORD";
$db_name="DB_NAME";
mysql_connect($host,$username,$password)or die(mysql_error());
mysql_select_db($db_name)or die(mysql_error());
?>
Echo create a query and echo the results in a table:
<table style="background:#FFF; color:#000;">
<?php
$query = "SELECT username,name,email FROM j25_users ";
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($result)) {
echo '<tr><td>',$row["username"],'</td><td>',$row["name"],'</td><td>',$row["email"],'</td></tr>' ;
}
?>
</table>
You will need to change j25_users to the correct prefix of your database tables.
Update: Much better to import the framework to get the user object.
Hope this comes in handy for you. Regards.
If you want to skip using Joomla! functions, you can query the Joomla! database. Join tables js25_session and js25_users with the user id. This way, you can get every currently logged-in user and all guests on the website (and possibly the number of online users).
