Languages

How add multilanguage ?

Something like this ?

$pagelang = get_bloginfo(‘language’); //this line to check the active lang
$url = ‘https://www.google.com/recaptcha/api.js’;
$url = add_query_arg( array(
‘onload’ => ‘recaptchaCallback’,
‘render’ => ‘explicit’,
‘hl’ => $pagelang), $url ); //
