Polylang plugin documentation talks about non translatable custom taxonomy. I'm using the plugin Media Libray Assistant, which creates a custom media taxonomy named "attachment category". I woud like the terms of such taxonomy to be non translatable, but by default they are.

Is it possible to tell to Polylang (maybe programmatically) that a certain taxonomy does not need a language specification?

Thanks in advance for your attention.

• when you go in the backend "Languages" -> "Settings", you can choose toxonomies in "Custom post types and Taxonomies". it's this setting you was searching for ? – mmm Commented May 7, 2018 at 5:28
• @mmm Unfortunately for some reason (a bug?) the "attachment category" taxonomy created by plugin Media Library Assistant is not listed there, that also why I asked help. – mmj Commented May 7, 2018 at 9:02

Use the following hook and replace custom_tax with your taxonomy slug

add_filter( 'pll_get_taxonomies', 'add_tax_to_pll', 10, 2 );
 
function add_tax_to_pll( $taxonomies, $is_settings ) {
    if ( $is_settings ) {
        unset( $taxonomies['custom_tax'] );
    } else {
        $taxonomies['custom_tax'] = 'custom_tax';
    }
    return $taxonomies;
}

It seems that the plugin Media Library Assistant is deliberately setting its custom taxonomy category_attachment as translatable by means of configuration file wpml-config.xml. Therefore changing the line

<taxonomy translate="1">attachment_category</taxonomy>

to

<taxonomy translate="0">attachment_category</taxonomy>

should do the trick. However I did not try myself because I'm not sure of what happens to existing taxonomy terms having a language specification.
