siteUrl in Twig templates not working

Question

I've got a problem where siteURL wasn't working for a localized version of my site. I have a site in two languages — Russian and English, with Russian exposed under www.mysite.com and English under www.mysite.com/en/.

My problem was that siteUrl variable was always giving me a non localized version of the site URL (www.mysite.com instead of www.mysite.com/en/) on the pages in English, even though other localized features were working fine (strings were translated into English, correct entries output etc.). See below for the solution.

Answer 1

The answer to this is that in the general.php I had a setup which somehow was giving trouble when setting siteUrl. Things were like this:

return array(
    '*' => array(
        'omitScriptNameInUrls' => true,
    ),
    'siteUrl' => array(
        'ru' => 'http://www.mysite.com/',
        'en_us' => 'http://www.mysite.com/en/'
    )
);

While seemingly correct, in this setup siteUrl should be moved into '*' block, otherwise there comes the problem that I described earlier. So the correct version is this:

return array(
    '*' => array(
        'omitScriptNameInUrls' => true,
        'siteUrl' => array(
            'ru' => 'http://www.issuesinlinguistics.ru/',
            'en_us' => 'http://www.issuesinlinguistics.ru/en/'
        )
    )
);
