Support » Plugin: Polylang » [Contribution] Undocumented filter pll_the_languages_args

  • Hey Chouby!

    One more time, thank for your awesome work 🙂

    I’ve had a task today to add a language switcher to WordPress menu, but the client wanted it to show language code instead of name, like:

    Home | About | Contact | DE

    instead of

    Home | About | Contact | Deutsch

    I don’t want to complicate things, and if Polylang provides a standard language switcher for the nav_menus, let’s use it. None of the methods discussed in other topics here worked for this case, so I went to study the code. There’s an undocumented filter pll_the_languages_argsin PLL_Switcher->the_languages() (see here) which perfectly fits for this purpose. Here’s a piece of code that might be useful for others:

     * Display languages as slugs instead of full name.
     * @param $args array Merged array of defaults and user settings for language selector
     * @return array Modified array of arguments
    function pss_language_as_slug( $args ) {
    	$args['display_names_as'] = 'slug';
    	return $args;
    add_filter( 'pll_the_languages_args', 'pss_language_as_slug', 10, 1 );

    It would be nice to document it in filters section on Polylang docs website.

    I must admit that not every filters are documented. I will add this one with your example.

    Yes, I understand that. Even in WP Core not all of them are documented properly or even at all 🙂

    Is there any chance of having this as an option in the menu item/widget?
    Wouldn’t want to have to create child themes for just one filter 🙂
