Question

I am making an plugin, and inside my admin page (Which i add by add_menu_page() function) i call this function pll_the_languages(["raw" => 1])) but its return nothing,on client side its work fine. I added many languages on Polylang setting page. How can i get Polylang available languages from an admin page ?

Was it helpful?

Solution

According to Polylangs Function Reference, pll_the_languages

Displays a language switcher.

And most probably it uses some additional CSS/JS to work. If you want to get the list of languages and display them with your custom code, then you can use this function instead:

pll_languages_list($args);

and it will return the list of languages.

$args is an optional array parameter. Options are:

  • ‘hide_empty’ => hides languages with no posts if set to 1 (default: 0)
  • ‘fields’ => returns only that field if set. Possible values are ‘slug’, ‘locale’, ‘name’, defaults to ‘slug’

OTHER TIPS

Polylang offers the function pll_languages_list() but note this will return only one type of value slug.

You can use get_terms to query all languages with the name and slug included.

get_terms( 'term_language', [ 'hide_empty' => false ] );

You can get an array with the language details using the following call:

if (function_exists('pll_languages_list')) {
    return pll_languages_list(array('fields' => array()));
}

The result is an array which you can play with to your liking...
