duplicated languages string/flags with pll_the_languages

Hello, thanks for developing Polylang.

I am having a weird issue when using pll_the_languages function. The list of languages it outputs is duplicated, there are 2 flags/strings for each language.

This is the code I’m using in functions.php:
```
/* Add Polylang-plugin language switch to header*/

function add_language_switch() {

// check existance of pll_the_languages to prevent wordpress for breaking when Polylang is not available (for example when being updated)
  if (function_exists('pll_the_languages')) {
    echo '<ul>' . pll_the_languages(array('show_flags'=>1,'show_names'=>0)) . '</ul>';
  } else {
    echo 'Polylang not available';
  }
}

add_action('mytheme_header','add_language_switch', 30);
```
What am I doing wrong?
Also is this a good way to use Polylang?

On a side note, when I add polylang switcher to the menu through the wordpress menu settings the languages are not duplicated.

Thanks in adv.

To help understand better, here is the outputted HTML (there are three languages flags, each showing twice):

<li class="lang-item lang-item-4 lang-item-it current-lang"><a hreflang="it" href="http://mywebsite.com/it/"><img src="http://mywebsite.com/wp-content/plugins/polylang/flags/it_IT.png" title="Italiano" alt="Italiano"></a></li>

<li class="lang-item lang-item-7 lang-item-en"><a hreflang="en" href="http://mywebsite.com/en/"><img src="http://mywebsite.com/wp-content/plugins/polylang/flags/en_US.png" title="English" alt="English"></a></li>

<li class="lang-item lang-item-11 lang-item-es"><a hreflang="es" href="http://mywebsite.com/es/"><img src="http://mywebsite.com/wp-content/plugins/polylang/flags/es_ES.png" title="Español" alt="Español"></a></li>

<-- duplication occurs here but notice how the following languages are enclosed in a <ul> tag, which is exactly how I coded it in functions.php, so it seems that the dupes are those above -->

<ul>
<li class="lang-item lang-item-4 lang-item-it current-lang"><a hreflang="it" href="http://mywebsite.com/it/"><img src="http://mywebsite.com/wp-content/plugins/polylang/flags/it_IT.png" title="Italiano" alt="Italiano"></a></li>

<li class="lang-item lang-item-7 lang-item-en"><a hreflang="en" href="http://mywebsite.com/en/"><img src="http://mywebsite.com/wp-content/plugins/polylang/flags/en_US.png" title="English" alt="English"></a></li>
<li class="lang-item lang-item-11 lang-item-es"><a hreflang="es" href="http://mywebsite.com/es/"><img src="http://mywebsite.com/wp-content/plugins/polylang/flags/es_ES.png" title="Español" alt="Español"></a></li>

</ul>

If anybody has a clue please help… I really have no clue how this is happening and how I can fix it.
Thanks

Duplicates don’t show up if I use either

pll_the_languages(array('raw'=>1))

pll_languages_list($args)

But I’d still prefer to go with pll_the_languages() because I don’t have to work on arrays and build the HTML.

Can someone help?

Hi!

That’s because you use ‘echo’ and ‘pll_the_languages’ already uses it (by default). You can use the parameter 'echo' => 0 to avoid this.

Ouch!
I should have inspected polylang code a bit better! Or I could have simply tried without calling echo on it, which I had planned, among all other tries, but it somehow slipped out of my brain… and I ended up building the PHP/HTML myself.. oh well.. let’s take it as a PHP brush up 🙂

Cheers and thanks for your support though! Appreciated!
