Display lang switch only if there is translation

Hello,

I am really sorry, I realised I totally forgot to answer your question. As it is 2 months old, I am sure you dont need it anymore, but here is the solution however.

I also will try to make it simpler in a future version.

add_action('sublanguage_custom_switch', function($languages, $sublanguage) {

	if (is_singular()) {

		// count translations

		$queried_object = get_queried_object();

		$translation_count = 0;

		foreach ($languages as $language) {

			if (!$sublanguage->is_current($language)) {

				$translation = $sublanguage->get_post_translation($queried_object->ID, $language->ID);

				if ($translation && $translation->post_content != $queried_object->post_content) {

					$translation_count++;

				}

			}

		}

	}

	if (!is_singular() || $translation_count > 0) {

		// print the language switch 

		$output = '<ul>';

		foreach ($languages as $language) {

			$output .= sprintf('<li class="%s%s"><a href="%s">%s</a></li>',
				$language->post_name,
				($sublanguage->current_language->ID == $language->ID ? ' current' : ''),
				$sublanguage->get_translation_link($language),
				apply_filters('sublanguage_language_name', $language->post_title, $language)
			);

		}

		$output .= '</ul>';

		echo $output;

	}

}, 10, 2);

Hi Maxime!

I tried to put this code on my test wordpress but it’s not working. I put it on functions.php of the theme and I put it on the sublanguage.php but nothing. :/

Regards

Actually, this works only if you use the “custom” language switch. You’re probably using the switch into the wordpress menu.

ahh, What does mean “custom” language switch?

Thanks!

Solution —

I installed “In Page Script plugin” and I added the next code on the footer script section:

<script type="text/javascript">
jQuery(function ($) {
	$("li.sublanguage a:contains('ES')").html('<img src="your-image-spain-flag.png"/>');
	$("li.sublanguage a:contains('EN')").html('<img src="your-image-english-flag.png"/>');
});
</script>

*You need to put in Sublanguage/Languages titles, a name short as is: ES, EN in my case for
ES= spanish language and EN= UK language.

One of the ways to solve this problem short term while the final version is not ready

Thanks to Maxime for your help
