Hello Folks!

 

I looked here in the forums about a way to get auto-translate working on WHMCS and i only found a hook based on ip address.

For most of users, IP address is not accurate to get the correct language (example: switzerland has 3 languages: french, italian and german. A spanish living in UK). So, i focused on the browser language.

Many people use their computers on their foreign language (browser included) but it's not a rule to follow.

 

So, for those who want to get whmcs showed up with the correct language for the users, i developped the following hook based on another that i found on the whmcs blog for a very old version.

 

Just create the file includes/hooks/switch-language.php and place the following code inside of it:

 

<?php

$country_to_language = array(
'default' => 'english',
'AR' => 'arabic',
'AR-DZ' => 'arabic',
'AR-BH' => 'arabic',
'AR-EG' => 'arabic',
'AR-IQ' => 'arabic',
'AR-JO' => 'arabic',
'AR-KW' => 'arabic',
'AR-LB' => 'arabic',
'AR-LY' => 'arabic',
'AR-MA' => 'arabic',
'AR-OM' => 'arabic',
'AR-QA' => 'arabic',
'AR-SA' => 'arabic',
'AR-SY' => 'arabic',
'AR-TN' => 'arabic',
'AR-AE' => 'arabic',
'AR-YE' => 'arabic',
'AZ' => 'azerbaijani',
'CA' => 'catalan',
'ZH' => 'chinese',
'ZH-HK' => 'chinese',
'ZH-CN' => 'chinese',
'ZH-SG' => 'chinese',
'ZH-TW' => 'chinese',
'HR' => 'croatian',
'CS' => 'czech',
'DA' => 'danish',
'NL' => 'dutch',
'NL-BE' => 'dutch',
'EN' => 'english',
'EN-AU' => 'english',
'EN-BZ' => 'english',
'EN-CA' => 'english',
'EN-IE' => 'english',
'EN-JM' => 'english',
'EN-NZ' => 'english',
'EN-PH' => 'english',
'EN-ZA' => 'english',
'EN-TT' => 'english',
'EN-GB' => 'english',
'EN-US' => 'english',
'EN-ZW' => 'english',
'ET' => 'estonian',
'FA' => 'farsi',
'FR' => 'french',
'FR-BE' => 'french',
'FR-CA' => 'french',
'FR-FR' => 'french',
'FR-LU' => 'french',
'FR-MC' => 'french',
'FR-CH' => 'french',
'DE' => 'german',
'DE-AT' => 'german',
'DE-DE' => 'german',
'DE-LI' => 'german',
'DE-LU' => 'german',
'DE-CH' => 'german',
'HE' => 'hebrew',
'HU' => 'hungarian',
'IT' => 'italian',
'IT-CH' => 'italian',
'MK' => 'macedonian',
'NO' => 'norwegian',
'NB' => 'norwegian',
'NN' => 'norwegian',
'PT-BR' => 'portuguese-br',
'PT' => 'portuguese-pt',
'RO' => 'romanian',
'RO-MO' => 'romanian',
'RU' => 'russian',
'RU-MO' => 'russian',
'ES' => 'spanish',
'ES-AR' => 'spanish',
'ES-BO' => 'spanish',
'ES-CL' => 'spanish',
'ES-CO' => 'spanish',
'ES-CR' => 'spanish',
'ES-DO' => 'spanish',
'ES-EC' => 'spanish',
'ES-SV' => 'spanish',
'ES-GT' => 'spanish',
'ES-HN' => 'spanish',
'ES-MX' => 'spanish',
'ES-NI' => 'spanish',
'ES-PA' => 'spanish',
'ES-PY' => 'spanish',
'ES-PE' => 'spanish',
'ES-PR' => 'spanish',
'ES-ES' => 'spanish',
'ES-UY' => 'spanish',
'ES-VE' => 'spanish',
'SV' => 'swedish',
'SV-FI' => 'swedish',
'SV-SV' => 'swedish',
'TR' => 'turkish',
'UK' => 'ukranian',
// NOTE: You can add more below
);

if(strpos($_SERVER['REQUEST_URI'], $customadminpath) === false && !isset($_SESSION['switch-language'])
&& $_SESSION['uid'] == false) {
$_SESSION['switch-language'] = true; // prevent from redirecting back again in this session
// we will add more here....
}

$current_country = strtoupper(substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2));

$language = $current_country != '' && isset($country_to_language[$current_country]) 
               ? $country_to_language[$current_country]
               : $country_to_language['default'];

if(!isset($_SESSION['Language']) || $_SESSION['Language'] != $language) {
       $location = '?language='.$language;     
       if($_SERVER['QUERY_STRING'] != '')
           $location .= '&'.$_SERVER['QUERY_STRING'];

       ob_clean();
       header('location: '.$location);
       die();
   }

 

Once done your whmcs will switch language automatically right away. The hook is loaded automatically.

This won't change the currency has it's a bit more invasive.

 

I hope this will help you.

Hello there,

 

The code is working well in WHMCS 7 client area but there is a problem with the admin login. When I try to access to admin url, I get an error in the browser: Too many redirections....

 

This script add a infinite loop in the administrator url:

 

?language=spanish&language=spanish&language=spanish&language=spanish&amp;language=spanish&amp;amp;language=spanish

 

This is the old post blog:

 

https://blog.whmcs.com/?t=67990

 

Anybody has a script or hook that works ok?

I guess the issue is in this statement:

strpos($_SERVER['REQUEST_URI'], $customadminpath) === false

I think that checking $customadminpath is not a valid method, because:

  • it may be undefined (if you have not a custom admin directory...)
  • even if defined, it may be slightly different from REQUEST_URI

So, the question is: 

  • how to check if a code is running in client area or in admin area?

or even:

  • how to make a hook which works in client area only?

This version seems to be working fine (test it before using in production environment).
Only issue: user is not able to switch language himself. Even if he select another language from the menu, client area will stay on his browser's language. 

<?php

add_hook('ClientAreaPage', 1, switch_language($vars));

function switch_language($vars) {
 
$country_to_language = array(
'default' => 'english',
'AR' => 'arabic',
'AR-DZ' => 'arabic',
'AR-BH' => 'arabic',
'AR-EG' => 'arabic',
'AR-IQ' => 'arabic',
'AR-JO' => 'arabic',
'AR-KW' => 'arabic',
'AR-LB' => 'arabic',
'AR-LY' => 'arabic',

       ob_clean();
       header('location: '.$location);
       die();
   }
	
}

I made a slight improvement to the above code to prevent the loops and forced language changes..

change the last lines to this: 

if(!isset($_SESSION['Language']) || $_SESSION['Language'] != $language) {
       $location = '?language='.$language;
       if($_SERVER['QUERY_STRING'] != '' && strpos($_SERVER['QUERY_STRING'],'?language')===0) {
                $location .= '&'.$_SERVER['QUERY_STRING'];
                ob_clean();
                header('location: '.$location);
                die();
       }
}

if the query string already contains a language= clause this prevents another one from being appended to it..

This should be funcationality in WHMCS Core.

As of today I think this hook is not working anymore.

Is someone able to test this and provide a fix that works with WHMCS V8.6.1?

Adding all info in this topic: the current (broken code) should be:

 

```<?php

add_hook('ClientAreaPage', 1, switch_language($vars));

function switch_language($vars) {
 
$country_to_language = array(
'default' => 'english',
'AR' => 'arabic',
'AR-DZ' => 'arabic',
'AR-BH' => 'arabic',
'AR-EG' => 'arabic',
'AR-IQ' => 'arabic',
'AR-JO' => 'arabic',
'AR-KW' => 'arabic',
'AR-LB' => 'arabic',
'AR-LY' => 'arabic',
'AR-MA' => 'arabic',
'AR-OM' => 'arabic',
'AR-QA' => 'arabic',
'AR-SA' => 'arabic',
'AR-SY' => 'arabic',
'AR-TN' => 'arabic',
'AR-AE' => 'arabic',
'AR-YE' => 'arabic',

$current_country = strtoupper(substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2));

$language = $current_country != '' && isset($country_to_language[$current_country]) 
               ? $country_to_language[$current_country]
               : $country_to_language['default'];

if(!isset($_SESSION['Language']) || $_SESSION['Language'] != $language) {
       $location = '?language='.$language;
       if($_SERVER['QUERY_STRING'] != '' && strpos($_SERVER['QUERY_STRING'],'?language')=== false) {
                $location .= '&'.$_SERVER['QUERY_STRING'];
                ob_clean();
                header('location: '.$location);
                die();
       }
    }
}
 

?>
