My theme (Novo Theme) lets you create pages as footers.

I created a footer in German and one in English and linked them in polylang.

In Polylang Settings > Custom post types and Taxonomies I checked everything including “Footers (yprm_footer_builder)”

The footer being displayed is always the one selected in Appearance -> Customize.

I tried adding

to the page template as suggested by Google AI.

I also tried adding

function switch_footer_language() {
    if(pll_current_language=='th') {
        get_footer('footer_th.php');

    } elseif(pll_current_language=='en') {
        get_footer('footer_en.php');
    }
}

as suggested at Switch footer for different languages on WordPress website using Polylang plugin and Footer in multiple languages free WordPress

I couldn’t even get it to echo “DE” or “EN” depending on language, let alone to change the footer.

As far as I understand from posting on wordpress stackexchange at https://wordpress.stackexchange.com/questions/428859/changing-footer-according-to-language (question closed because outside their scope), I don’t need to load footer_en or footer_de but a page.

Different themes (like Avada Theme) apparently work by selecting the language as described here: Footer using Avada Theme in WordPress and the Polylang Plug-In but not Novo

I also contacted Envato Theme Support but got told customisation is beyond their scope. I have some programming skills and some worpress knowledge but not enough to take a good guess on where to start looking which support also didn’t want to tell me.

So, my questions are:

1. How do I find the location where the footer page gets picked?

2. Can I change it according to Polylang-Language using php? Would the ybove code be correct for querying the langauage set by polylang?

3. Would I (probably) have to change each template the theme provides or is there a more central location?
