Hi guys!

I searched for help in the forum, but didn't find a solution yet... I use Joomla v2.5.7 (with Community Builder v1.8.1). I upgraded K2 from v2.5.7 to v2.6.1 and all my registered visitors got that fatal error ("Fatal error: Class 'K2Table' not found in xxx/administrator/components/com_k2/tables/k2user.php on line 13").

If I clear my browser's cache and cookies the site works as intented. But the error can be reproduced with the following three steps:

1.) Check the box "Remember Me" and log in.
2.) Close your browser while being logged in.
3.) Open your browser and visit the site again. The error message appears again.

I can get rid of that error again and again by clearing my browser's cache and cookies as stated above. But that error will come back after closing my browser while being logged in. For me it seems like an error with the cookies... A new install of the version 2.6.1 didn't help. Any idea how to fix that? Thanks in advance!

Hi. Just tested and i cannot reproduce the issue. Are you using mod_login, mod_k2_user or mod_cblogin to perform the login?

Hi Lefteris!

I user mod_cblogin (the login module of the Community Builder). The other two (mod_login and k2_user) are un-published...

Hi. I still cannot reproduce the issue. Have you reported this to the CB forums?

Not yet, since I think it's a bug of K2. With version 2.5.7 of K2 it works as intended. I will try to reorder my system plug-ins ( this thread gave me an idea) and report back then.

Same issue here with same error in log.
After a user has been logged in. session expired and then logges in again the errror comes up!
User IS available in the K2 users database.
I have set k2 system plugin to -1 and i'll test more.

When i know more i'll post it here

@Jasper

Is the issue solved? Please provide some feedback on this.

When re-ordering the plugins it is "solved". Although i don't think this should matter.

Jasper

It worked! Setting the K2 plugin to "-1" in its order solved the problem for me as well.

(Sorry for the late reply, guys. I didn't have the time to install and test it until today.)

Well, to be more precise, the K2 plugin has to be loaded BEFORE the "Remember Me" plugin. It works then, but the "Remember Me" function is broken after changing the plugins' order. Your browser will forget you were logged in after you have closed it (even if the user checked "Remember Me" box on login).

Does anybody know how this can be fixed?

My configuration:

Joomla! v2.5.8
Community Builder v1.9
K2 v2.6.2
Kunena v2.0.3

Hi,

we've encountered the same problem. I can't authenticate through a webs-service with Joomla when the K2-User Plugin is on.

Its a standard installation and my Joomla-Web-Service is done properly and never had a problem, since the K2-User-Plugin.

However, please fix this soon.

thank you.

Hello guenter,

I can see a lot of errors are from the com_xas extension. Have you tried reordering the plugins or disabling the K2 user plugin ?

hi,
as far I can see in the stack-trace, the crash comes from you :

PHP Fatal error: Class 'K2Table' not found in /com_k2/tables/k2user.php

Re-ordering or disabling is not an option. Your component shouldn't crash at all at the login chain. Basically this crash causes that people can't use our component without explaining them that the K2-User-Plugin must be reordered or disabled.

Please fix this. Thank you. The crash comes also up with other webservice based plugins which use the Joomla-API to authenticate a user.

@guenter

First of all you didn't mention what version of Joomla! and K2 you are using. Ensure that both of them are up to date. For your information K2Table class is loaded by the K2 system plugin on the "onAfterInitialise" event in order to make the class available to the system. You can see the code at file /plugins/system/k2/k2.php line 414. So first of all you need to ensure that K2 system plugin is enabled, since this is a requirement for K2 in order to operate. Beyond this, i cannot know what your extension is doing and why the class is not available. In any case you can still use a simple require_once to the table.php file and fix the issue.

Hi,
thank you. We're testing against the latest versions of K2 and the Joomla 2.5.x series. We do this tests always with fresh and standard installations.

Does that mean you are not fixing your own code and leave it to us ? Please confirm this. There is no problem to bloat our code because of other plugins, we are used to this since we're working for Joomla :-)

This is how we authenticate a user through a web service API :

$userId = -1;

$credentials = array('username' => $username, 'password' => $password);
$options = array('silent' => true);

$app = JFactory::getApplication();

// Save our guest session so we can destroy it.
$session = JFactory::getSession();
$guestSessionId = $session->getId();

// Login will create a new session
$successfulLogin = $app->login($credentials, $options);

// Destroy guest session row. Login forks the session and we will end up with a bunch of guest rows if we don't.
jimport('joomla.database.table');
$storage = & JTable::getInstance('session');
$storage->delete($guestSessionId);

Whilst the authentification, its crashing in your component whilst it shouldn't at all.

And introducing 'bug' fixes within our code for other plugins shouldn't be the way, or ? It also shouldn't matter what our plugin does.

The methods your describe to get around your bug is not acceptable for standard installation or user. I mean how is doing such things ? This is against all QA policies we know.
thank you

please don't find this offending. its just annoying to make such huge efforts

So you prefer to have your software crashing and disappoint your users. instead of adding a line of code? It's fine for me. But just your information, in order to apply a fix we first need to reproduce the issue and of course detect what's causing it. Finally note that this will be done when we have some time to look into it and not now. Please don't find this offending.

Ok, forget it. we fix it for you. Where can we send the code ?

And lol, adding bug fixes for other plugins : no worry, as said we are used to this kind of 'working' with Joomla and its plugin developers. That was not a joke but seriously, this is how it works here ?


Btw, you've got all what you need. simply use the login example function and you will see what your software does : crash at a very important platform function.

here, your new login function, taking care about the pre-conditions :

function onLoginUser($user, $options)
{
$params = JComponentHelper::getParams('com_k2');
$mainframe = JFactory::getApplication();
if ($mainframe->isSite())
{
$tmp = JFactory::getUser();
$db = JFactory::getDBO();
$db->setQuery("SELECT id FROM #__users WHERE username = ".$db->Quote($user));
$id = $db->loadResult();

if ($id)
{
$k2id = $this->getK2UserID($id);
}
else
{
$k2id = false;
}

JTable::addIncludePath(JPATH_ADMINISTRATOR.DS.'components'.DS.'com_k2'.DS.'tables');
JLoader::register('K2Table', JPATH_ADMINISTRATOR.'/components/com_k2/tables/table.php');
$row = JTable::getInstance('K2User', 'Table');

if ($k2id)
{
$row->load($k2id);
}
else
{
$row->set('userID', $tmp->id);
$row->set('userName', $tmp->name);
$row->set('group', $params->get('K2UserGroup', 1));
}
$row->ip = $_SERVER;
$row->hostname = gethostbyaddr($_SERVER);
$row->store();

if ($params->get('cookieDomain') && $id)
{
setcookie("userID", $id, 0, '/', $params->get('cookieDomain'), 0);
}
}
return true;
}


So, finally. No need to force users to do 'strange' things like 'disabling' or 'reordering' your own plugin. I'm glad you see it like me :-)

Hi,

is there an estimate when this bug will fixed, or when it will be available in a next release ?

We've a dozen of people a day reporting the problem and its really tedious to tell them, that the K2 user plugin must be disabled whilst logging into Joomla through our plugin.

Thank you very much.
