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()

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

    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:

/**
     * 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:

    /**
     * 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...

  /**
     * 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.

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 )
