Display language two-letter codes instead of language names

Yes, you can. Display slug instead of name. Or edit name from “English” to “EN”.

Check out Polylang function reference at https://polylang.wordpress.com/documentation/documentation-for-developers/functions-reference/

As you can see pll_the_languages() allows you to use some arguments. With

<?php pll_the_languages(array('display_names_as'=>'slug')); ?>

you display the slug instead of the name.
Put this code line in your theme where you want to get the language switcher.

I was looking for a solution to this issue and one of the first google results led to this page. My situation is a bit different as I want to use a standard Polylang widget in navigation menu, and calling <?php pll_the_languages(array(‘display_names_as’=>’slug’)); ?> does not solve this. So, I’ve studied the code and found a useful filter ‘pll_the_languages_args’. And I wrote this code to change the value from functions.php:

/**
 * 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 );

Hope this will help someone.
