PHP functions for language switching

I think I found it:
get_translate_post_link

No, I was wrong, this is for new page in admin part

I found the solution, but it was more troublesome than expected. I have only two languages on my page, so example is simplified in regards to general solution.
If you would accept my contribution, I will write and expose functions for developers to do exactly that simpler – return url of the page when language is given and return language of current page

Here is my code:

<?php
function nLanguage_menuswitch_output() {
	// 1- english, 2-croatian
	$language_to_switch_to_id =
		(nLingual\Registry::current_language()->id == 1) ? 2 : 1;
	// get language object
	$language_to_switch_to = nLingual\Registry::get_language($language_to_switch_to_id);
	// get target url
	$target_url = nLingual\Rewriter::localize_here($language_to_switch_to);
	// output language menu
	if ($language_to_switch_to_id == 1) :
	?>
	HRVATSKI / <a href="<?= $target_url ?>" aria-label="Change language to english">ENGLESKI</a>
	<?php
	else :
	?>
	<a href="<?= $target_url ?>" aria-label="Promijeni jezik u hrvatski">HRVATSKI</a> / ENGLESKI
	<?php
	endif;
}

Hi,

The plugin offers a way to add these links via the nav menu (a Language Links box will appear in the left column of the menu editor), however there’s not much of a built-in utility for printing a language nav outside of the template, since I didn’t want to lock-in the markup (though I could write something with config options for it).

In most cases on my projects, I write something like this in the header template.

<nav class="language-nav" role="Language">
    <?php foreach ( nLingual\Registry::languages() as $i => $language ) : ?>
        <?php echo $i ? '/' : ''; ?>
        <a  rel="alternate"
            href="<?= nLingual\Rewriter::localize_here( $language ) ?>"
            hreflang="<?= $language->locale_name ?>"
            class="<?php echo nLingual\Registry::is_language_current( $language ) ? 'is-current' : ''; ?>"
        ><?= $language->short_name ?></a>
    <?php endforeach; ?>
</nav>

That will print a <nav> element with an >a< link for each language the site supports, flaging the current one with the is-current class. The aria-label might be tricky to implement (maybe a sprintf() call using a localized string), but otherwise that should do the job.
