Polylang Shortcode

functions.php

// Polylang Shortcode - https://wordpress.org/plugins/polylang/
// Add this code in your functions.php
// Put shortcode [polylang] to post/page for display flags

function polylang_shortcode() {
	ob_start();
	pll_the_languages(array('show_flags'=>1,'show_names'=>0));
	$flags = ob_get_clean();
	return $flags;
}
add_shortcode( 'polylang', 'polylang_shortcode' );

To modify your polylang_shortcode so it:
1. Only shows languages other than the current one, and
2. Displays both flag and language name,

You can update the function like this:

function polylang_shortcode() {
	ob_start();
	pll_the_languages(array(
		'dropdown'    => 0,
		'show_flags'  => 1,
		'show_names'  => 1,
		'hide_current' => 1, // Hides current language
		'raw'         => 0   // Output as HTML
	));
	return ob_get_clean();
}
add_shortcode('polylang', 'polylang_shortcode');

✅ Explanation:
• 'hide_current' => 1 – hides the current language.
• 'show_flags' => 1 – shows the language flag.
• 'show_names' => 1 – shows the language name.
• 'raw' => 0 – outputs HTML instead of raw array.

💡Usage:

Add [polylang] in any post, page, or widget, and it will display only the other available languages with both flag and name.
