__() & _e() do not support LANG attribute

    It looks like the __() and _e() functions do not honor the lang attribute of HTML. For example

    <html lang=”en”>
    …
    <body>
    <?php _e(‘Red’,’textdomain’); ?>
    <div lang=”it”>
    <?php _e(‘Red’,’textdomain’); ?>
    </div>

    should return

    Red
    Rosso

    but it does not. It returns

    Red
    Red

    Any idea why?

    They’re not supposed to, that’s not how they work. Those functions use the language defined in WordPress’ settings and get their translations from a translation file in the theme or plugin. See the Localization page of the Theme Developer Handbook for more.

    If you’re using a static HTML attribute then you probably shouldn’t be using the translation functions at all, as the use of the attribute with a hard-coded value implies that the language won’t/can’t change.

    I know how to use i18n in WordPress. The problem is not the file, but the fact that in a site of a specific language, I have pages in other languages. So, in those pages, the same plug-in should use another language file. The problem is that I do not know how to FORCE the language in a specific page.

    SOLVED! I added this function to functions.php

    if( ! function_exists('load_specific_textdomain') ){	
	function load_specific_textdomain( $textdomain = 'default', $locale = null ) {
		if ( null === $locale ) {
			$locale = is_admin() ? get_user_locale() : get_locale();
		}
	 
		// Unload previously loaded strings so we can switch translations.
		unload_textdomain( $textdomain );
	 
		$return = load_textdomain( $textdomain, WP_LANG_DIR . "/$locale.mo" );
	 
		if ( ( is_multisite() || ( defined( 'WP_INSTALLING_NETWORK' ) && WP_INSTALLING_NETWORK ) ) && ! file_exists(  WP_LANG_DIR . "/admin-$locale.mo" ) ) {
			load_textdomain( $textdomain, WP_LANG_DIR . "/ms-$locale.mo" );
			return $return;
		}
	 
		if ( is_admin() || wp_installing() || ( defined( 'WP_REPAIRING' ) && WP_REPAIRING ) ) {
			load_textdomain( $textdomain, WP_LANG_DIR . "/admin-$locale.mo" );
		}
	 
		if ( is_network_admin() || ( defined( 'WP_INSTALLING_NETWORK' ) && WP_INSTALLING_NETWORK ) )
			load_textdomain( $textdomain, WP_LANG_DIR . "/admin-network-$locale.mo" );
	 
		return $return;
	}
}

    then I used the following block of code:

    // $lang is the language you wish to temporarily load
// $domain is the text domain 
//       if $lang is null, use the current locale

if ($lang != null) {
	$clang = is_admin() ? get_user_locale() : get_locale();
	load_specific_textdomain($domain, $lang);
}

// Place here the code containing __($string_to_be_translated, $domain)

if ($lang != null) {
	load_specific_textdomain($domain, $clang);
}
