hi, i noticed i can set the freichat language, but i have a multilanguage site, i want to adapt the chat to joomla user language.
I guess it's about a little hack..could you help me?

i want to adapt the chat to joomla user language.

What do you mean by this ?
Do you want to add all freichat translations to Joomla ini files ?

Let us know your purpose for doing this , there may be a better way than some hacks .

i mean: if the user set joomla frontend in english, freichat should be english, if italian, freichat should be italian.

Yes, that is possible .

We can detect the current language in Joomla using

$lang = JFactory::getLanguage();
echo 'Current language is: ' . $lang->getName();

The problem is , FreiChat does not load the Joomla framework, so you cannot use this code directly .

So, before proceeding to the code, can you tell us how you installed freichat i.e did you install the joomla module or copy pasted the code in your template ?

i installed the module

Open joomla/modules/mod_freichatx/mod_freichatx.php

Around line 33 , replace

$document->addScript($host.'freichat/client/main.php?id='.$ses.'&xhash='.freichatx_get_hash($ses));

with

$lang = JFactory::getLanguage();
$language = $lang->getTag();
$document->addScript($host.'freichat/client/main.php?lang='.$language.'&id='.$ses.'&xhash='.freichatx_get_hash($ses));

Now, open freichat/arg.php , around line 120 , replace

$this->lang = $parameters['lang']; //Language please do not include .php here only file name

with

$this->lang = $_GET['lang']; //Language please do not include .php here only file name

But, the problem is that Joomla uses language file names as 'en-GB' but freichat uses names like 'english'.

So you need to rename all file names in freichat/lang directory .

For example , rename

freichat/lang/english.php

to

freichat/lang/en-GB.php

very thanks! but i get an error in js console

Failed to load resource: the server responded with a status of 500 (Internal Server Error) http://MYSITE.it/freichat/client/jquery/freichat_themes/freichatcss.php

That error looks unrelated to the previous changes .

Can you post the entire code[modified] in mod_freichatx.php ?

thanks for your help.
this is the module code

<?php
defined('_JEXEC') or die ('Direct Access is not allowed');

$host = JURI::root();


$document = JFactory::getDocument();

$session = JSession::getInstance("none",array());
$ses=$session->getId();

if(!function_exists("freichatx_get_hash")){
function freichatx_get_hash($ses){

       if(is_file(JPATH_SITE."/freichat/hardcode.php")){

               require(JPATH_SITE.'/freichat/hardcode.php');

               $temp_id =  $ses . $uid;

               return md5($temp_id);

       }
       else
       {
               echo "<script>alert('module freichatx says: arg.php file not
found!');</script>";
       }

       return 0;
}
}

//$document->addScript($host.'freichat/client/main.php?id='.$ses.'&xhash='.freichatx_get_hash($ses));

$lang = JFactory::getLanguage();
$language = $lang->getTag();
$document->addScript($host.'freichat/client/main.php?lang='.$language.'&id='.$ses.'&xhash='.freichatx_get_hash($ses));

$document->addStyleSheet($host.'freichat/client/jquery/freichat_themes/freichatcss.php');
?>

those are the last rows of the error log. basically your code doesn't works so well to me
see that require(lang/.php)

Can you make the following changes:

Open freichat/client/main.php

Replace , around line 3,

session_start();

with

session_start();  

$_SESSION['frei_lang'] = $_GET['lang'];

Now, open freichat/arg.php , around line 120 , replace

$this->lang = $_GET['lang']; //Language please do not include .php here only file name

with

$this->lang = $_SESSION['frei_lang']; //Language please do not include .php here only file name

uhm still errors..

i can provide you the ftp credentials if you want to check..

ok i see the freichat window and the multilanguage hack works, but it is stuck on "Getting list of online users"..so it doesn't works fine..

(i see some error in js console, and in php error log)
JS console:

There is some error in the query .

Can you try this :

Open freichat/server/drivers/JSocial.php

Around line 44, replace

//echo $query;

with

echo $query;

Now, load your website using chrome , open developer tools (f12) , click on network tab , click on any of the requests made by freichat , click on response tab for that request .

You should see a query in the response, paste the query here .

i see two requests:

• freichat/server/freichat.php?freimode=getmembers.....

  SELECT DISTINCT u.avatar,f.status_mesg,f.username,f.session_id,f.status,f.guest,u.alias AS profile_iden,f.in_room, c.value AS country
                               FROM frei_session AS f
                               LEFT JOIN z27s5_community_users AS u ON f.session_id=u.userid
                               LEFT JOIN  community_fields_value AS c ON c.user_id=f.session_id  
                              WHERE time>1407003466
                               AND f.session_id!=827
                               AND f.status!=2
                               AND f.status!=0
                               AND c.field_id=11
  

• freichat/server/freichat.php?freimode=getdata....

{"exist":false,"messages":[]}

please note the LEFT JOIN community_fields_value AS c ON c.user_id=f.session_id
maybe the problem is there.
i changed the 'alias': LEFT JOIN community_fields_value AS v
i noticed there already is an alias 'c' in getbuddies()
(i'm trying to add an extra field)

anyway i noticed sometimes for see the freichat window i have to reload the page after the login, the first time doesn't show anything..

Can you run the following query using phpmyadmin(or equivalent) in your database :

SELECT DISTINCT u.avatar,f.status_mesg,f.username,f.session_id,f.status,f.guest,u.alias AS profile_iden,f.in_room, c.value AS country
                             FROM frei_session AS f
                             LEFT JOIN z27s5_community_users AS u ON f.session_id=u.userid
                             LEFT JOIN  community_fields_value AS c ON c.user_id=f.session_id  
                            WHERE time>1407003466
                             AND f.session_id!=827
                             AND f.status!=2
                             AND f.status!=0
                             AND c.field_id=11

Post any errors that you may get .

Looking at the query , your LEFT JOIN looks wrong, it should be

LEFT JOIN  z27s5_community_fields_value AS c ON c.user_id=f.session_id

instead of

LEFT JOIN  community_fields_value AS c ON c.user_id=f.session_id

that's not the only silly mistake..
the table's name is community_fields_valueS!
BUT i fixed those 2 errors and i still dont get the user list

EDIT: wait a min:
now thats the response of the freichat request ... what the hack

ok i guess i solve, now the query works i just removed that echo you said to decomment

just a last thing i need about multilanguage:
soon i will translate the site in chinese, so since there is no freichat chinese translation, i need something to make the chat english (as i set in freichat backend) with chinese joomla.
With the current code i think i will face another error
so i need something like:

if(FREICHAT HAS THIS TRANSLATION) $this->lang = $_SESSION['frei_lang'];  
else $this->lang='en-GB';

anyway thanks, awesome support.

FreiChat by default loads the english translations if the language file is not present .
The only problem is the errors are not hidden, so freichat stops working .

So, to make freichat load even if a language file is not present, make the following change:

Open freichat/arg.php, Around line 318 , replace

$OtherLangInc = require 'lang/' . $this->lang . '.php';

with

$OtherLangInc = @include 'lang/' . $this->lang . '.php';

ok thanks, done that.

don't you think you should implement this feature in the next release?
