Support for multilanguage sites, Internationalization (I18N)

[mvlcek]

Code:

if (function_exists('i18n_load_texts')) {
    i18n_load_texts('user-login');
  } else {  
    i18n_merge('user-login', substr($LANG,0,2)) || i18n_merge('user-login', 'en');
  }

into the plugin file, but it still won't work correctly. In fact, it does work if I set the language using setlang and then navigate to a different page or refresh the login page. I have dug deeper into the code and found that $LANG does not change until after I navigate to a different page or rerun the same page, nor does $_SESSION['language']. I thought about setting $LANG = $language in the i18n_load_texts() function or something, but the $language variable is empty there for some reason.

I don't want to create a solution that is so hacky that I can't maintain the site...

Where have you added this code?
Looking at the plugin, it should be at the top of the function show_login_box(), welcome_message_login(), etc.
The order in which functionalities are executed:

• plugins are loaded, language is not known, thus putting the code at the top of the plugin file won't work
  
• on the index-pretemplate hook I18N determines the best language,
  
• thus it is known at the beginning of the template
  
• plugin functions like show_login_box are called, the language is known here, too
  

Hope this helps.
