Different URLs for different languages

This is small modification to make different URLs for different languages on your Dolphin site.

So site with site.com/ru/ with always has Russian language applied, and site.com/en/ with have English.

Also all URLs will be changed according to the current language.

1. Add symbolic links for each language in the Dolphin root folder, for example:

ln -s . en
ln -s . ru

2. Apply the following modification in header.inc.php

Instead of:

$site['url']               = 'http://domain.com/path/';

Add the following code:

$sUrlRoot = 'http://domain.com/path/';

$sPath = trim(parse_url($sUrlRoot, PHP_URL_PATH), '/');
$aMatches = array();
if (preg_match("/" . preg_quote($sPath, '/') . "\/([a-z]{2})\//", $_SERVER['PHP_SELF'], $aMatches) && isset($aMatches[1])) {
    // set the language detected in the URL
    $sUrlRoot .= $aMatches[1] . '/';
    $_COOKIE['lang'] = $aMatches[1];
}
else {
    // if no language is detected in the URL - redirect to English version homepage
    header('Location: ' . $sUrlRoot . 'en/');
}


$site['url']               = $sUrlRoot;

Don't forget to replace http://domain.com/path/ with your own domain and path.

3. Possible problems:

- lang switcher must be removed or changed, since old switcher will work incorrectly

- user must login again when site language is switched

- social login (like Facebook Connect) must be configured the special way - the redirect URI for each language must be specified

This is really a good idea for internationalization !

How about different languages for different forums?

Please could you describe the idea in more details ? 

Could you not add the feature that dolphin checks with the help of a catalogue of ip adresses where the user is located, and then taking the appropriate language?

There is already a feature which detects browser language and set Dolphin language accordingly. 

Oh, i did not know this. Can you tell me since when this is part of dolphin? 

I can't tell exactly, but this feature exists for a long time already.

Yes, If BOONEX forum supports 10 languages, The discussion list will become very long...

In fact, I can't read Russian, French, German, Italian, Spanish... so BOONEX does not need to list all the discussion lists in 10 languages at same time.

For example, Apple uses a different URL to correspond to a different language.

this is Apple's English discussion :

https://discussions.apple.com/content

this is Apple's French discussion :

https://communities.apple.com/fr/content

this is Apple's German discussion :

https://communities.apple.com/de/content

Japan's forum site is not the same, more special ! this is Apple's Japanese discussion :

https://discussionsjapan.apple.com/content

Now the dolphins system have just only one forum, maybe the dolphin system can also correspond to 10 languages, For example :

www. boonex.com/ru/forums/ (for Russian)

www. boonex.com/fr/forums/  (for French)

www. boonex.com/de/forums/ (for German)

www. boonex.com/ja/forums/ (for Japanese)

www. boonex.com/cn/forums/ (for Chinese)

Just copy the current forum to different languages and use a different MySQL data table name. More short list of forums, MySQL data read faster, web page display speed can be faster.

Thank you for the explanation, but it will require much more work than just a small modification.

My pleasure.

I know it's not so easy to support multiple languages, in fact it will be very difficult. but you know it's not "Mission: Impossible" !

Although the dolphin is not perfect, but I like it.

It would also be interesting to add the hreflang tags.

Which file should be modified to add these tags. URLactual would be a variable with the page url visited.

I currently have three languages.

<link rel="alternate" type="text/html" hreflang="es-ES" href="'+URLactual+'?lang=es" title="Español"/>

<link rel="alternate" type="text/html" hreflang="es-MX" href="'+URLactual+'?lang=mx" title="Mexico"/>

<link rel="alternate" type="text/html" hreflang="es-Ar" href="'+URLactual+'?lang=arg" title="Argentina"/>
