X5 - Setting the language based on user's browser language

In x4 I had some code that identified the user's language preference (using weighted values) and then displayed the site in the closest language possible with English as the default.

I did this by adding code before the get_language.php include that followed the logic below to set the store language.

1) Check user is not a robot and hasn't previously chosen a language
2) Set language based on browser setting and available languages

The user could set their language to override the auto detect using a cookie that lasted a year.

I want to do this in x5 but I can't work out which class/method to override so I can add in my extra detection code.

Any pointers?

I would look in classes/XLite/View/LanguageSelector/Customer.php at method isActiveLanguage()

Re: X5 - Setting the language based on user's browser language

I think I have this working. It's just hacks to files in var/ at the moment.

In var/run/classes/XLite/Controller/AControllerAbstract.php

Code:

    protected function doActionChangeLanguage()

    {

        $code = strval(\XLite\Core\Request::getInstance()->language);



        if (!empty($code)) {

            $language = \XLite\Core\Database::getRepo('\XLite\Model\Language')->findOneByCode($code);

            

            setcookie('store_language', $code, time()+31536000,"/"); // new line

            $_COOKIE['store_language'] = $code; // new line



            if (isset($language) && $language->getEnabled()) {

                \XLite\Core\Session::getInstance()->setLanguage($language->getCode());

                if (\XLite\Core\Auth::getInstance()->isLogged()) {

                    \XLite\Core\Auth::getInstance()->getProfile()->setLanguage($language->getCode());

                    \XLite\Core\Database::getEM()->flush();

                }

            }

        }



        $this->setReturnURL($this->getReferrerURL());

    }

In... var/run/classes/XLite/Core/Session.php
New Method:

Code:

/**

     * Browser language preferences

     *

     */

    public function browserLang($l=['en'],$u){return $l[array_keys($l,substr(explode(',',$u?:$_SERVER['HTTP_ACCEPT_LANGUAGE'])[0],0,2))[0]]?:$l[0];}

New method:

Code:

    /**

     * language cooookies!

     *

     */    

    public function getLanguageCookie()

    {      

            $store_language_codes = array('en','es','fr','de','it') ;

        $cookieLanguageCode = NULL;



        // -- If cookie is set

        if ( in_array(strtolower($_COOKIE[store_language]), $store_language_codes) ) {

                $cookieLanguageCode = strtolower($_COOKIE[store_language]) ;

                }



        return  $cookieLanguageCode;

    }

Totally rewritten method...

Code:

  /**

     * Get language

     *

     * @return \XLite\Model\Language

     */

    public function getLanguage()

    {

            

           if (!isset($this->language)){

                

                $langCookie = $this->getLanguageCookie();

                

                   if (!empty($langCookie)){

                           $this->language = \XLite\Core\Database::getRepo('XLite\Model\Language')

                                ->findOneByCode($this->getLanguageCookie());        

                        }  

                                

                   elseif (empty($langCookie)) { //no cookie set so best guess from browser      

                        $bestLanguageOption = $this->browserLang(['en','es','fr','de','it']);   

                            $this->language = \XLite\Core\Database::getRepo('XLite\Model\Language')

                                ->findOneByCode($bestLanguageOption);                      

                        }

                }      



        return $this->language;

    }

Probably could be made nicer.

Re: X5 - Setting the language based on user's browser language

Good job!

You are to wrap up your changes as a custom module as all changes to files in the var/ directory will disappear once you upgrade to a newer version, install a new module, or just run the redeploy routine.

You will be able to re-use the module for other X-Cart 5 stores and even list it at http://www.x-cart.com/extensions/addons (if you want :-))
