Language Switch Function

Question

I added a function to show a language button in nav menu, but the issue is that I have more than one menu and it duplicates the result. How can I specify what menu I want to show the language button in?

This is my code:

function new_nav_menu_items($items,$args) {

  if (function_exists('icl_get_languages') && !empty($args->theme_location)) {
    $languages = icl_get_languages();
    $current_lang = ICL_LANGUAGE_CODE;

    $nitem = "";
    if(count($languages) >= 1){
        foreach($languages as $l){
            if( $l['language_code'] != $current_lang ) {
                $nitem .= '<li class="menu-item"><a href="'.$l['url'].'"> '.$l['native_name'].'</a></li>';
            }
        }
      }
    }
  return $items . $nitem;
  }

add_filter( 'wp_nav_menu_items', 'new_nav_menu_items', 10,2 );

You are now only testing for the theme location not to be empty. This means that every non empty menu location will see the language button attached.

So, in stead of testing for emptyness you should be testing for a specific location. The name of that location depends on your theme, but suppose it's called 'primary-menu' you would have:

if (function_exists('icl_get_languages') && ($args->theme_location == 'primary-menu'))
