I have this code to start using Facebook SDK V4 with Codeigniter. This is the Facebook.php file inside Library Folder next to Facebook SDK folder files:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( session_status() == PHP_SESSION_NONE ) {
session_start();
}
define('FACEBOOK_SDK_V4_SRC_DIR', APPPATH . 'libraries/facebook/Facebook');
require_once("autoload.php");
require_once( 'Facebook/FacebookSession.php' );
require_once( 'Facebook/FacebookRedirectLoginHelper.php' );
require_once( 'Facebook/FacebookRequest.php' );
require_once( 'Facebook/FacebookResponse.php' );
require_once( 'Facebook/FacebookSDKException.php' );
require_once( 'Facebook/FacebookRequestException.php' );
require_once( 'Facebook/FacebookAuthorizationException.php' );
require_once( 'Facebook/GraphObject.php' );
require_once( 'Facebook/Entities/AccessToken.php' );
require_once( 'Facebook/HttpClients/FacebookHttpable.php' );
require_once( 'Facebook/HttpClients/FacebookCurlHttpClient.php' );
require_once( 'Facebook/HttpClients/FacebookCurl.php' );
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\Entities\AccessToken;
use Facebook\HttpClients\FacebookHttpable;
use Facebook\HttpClients\FacebookCurlHttpClient;
use Facebook\HttpClients\FacebookCurl;
class Facebook {
var $ci;
var $helper;
var $session;
var $permissions;
public function __construct() {
$this->ci =& get_instance();
$this->permissions = $this->ci->config->item('permissions', 'facebook');
echo $this->ci->config->item('api_id', 'facebook');
exit;
I am having some errors and found that the problem was the config variables are not loading.
My config file is like this:
<?php
$config['facebook']['api_id'] = 'api-id-key';
$config['facebook']['app_secret'] = 'app-secret-key';
$config['facebook']['redirect_url'] = 'http://neuronr.com/facebook/redirect';
$config['facebook']['permissions'] = array(
'email',
'user_location',
'user_birthday'
);
What am I doing wrong with the config files? I've read documentation and all seems correct to me.
Thanks for any help :)
Now my code worked. Just one line added:
$this->ci->load->config('facebook'); // this is the line that I added
Thanks for the inspiration :)

We had a similar problem recently. Local and beta servers worked but our production server did not.
The problem, V4 requires PHP version 5.4 or higher.

Might not be your problem but sounds really like ours. Hope it helps.
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.
Some more info about it:

I am using joomla 1.5.26 .
I can fetch the username and userid within the joomla file structure by
$user =& JFactory::getUser(); $user->username;.
Now I have a file which is neither under template folder nor under module folder nor under component folder. This is simply under root folder.
Now how can I fetch the logged in username?
Try this one create a new file on home page and access the username in this way
define( '_JEXEC', 1 );
define('JPATH_BASE', dirname(__FILE__) );
require_once( JPATH_BASE .'/includes/defines.php' );
require_once( JPATH_BASE .'/includes/framework.php' );
$mainframe =& JFactory::getApplication('site');
$user =& JFactory::getUser();
$user->username;
You cannot get/access any information if your file is not a type of Joomla! plugins.
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).
