## Filter language in Polylang for custom taxonomy

Question

Nevermind, I finally found. This is not documented, but going through Polylang code I found a way.

First retrieve the languages with their taxonomy id with

$lang = get_terms('term_language', ['hide_empty' => false])  which gives an object that can be called as $lang->name
and
$lang->term_id. Then, the wp_query should look like this: $args = array(
'post_type'      => ['post', 'page'],
'post_status'    => 'publish',
'numberposts' => -1,
'nopaging'    => true,
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => $taxonomy_custom_category, 'field' => 'name', 'terms' =>$taxonomy_term,
),
array(
'taxonomy' => 'language',
'field'    => 'term_taxonomy_id',
'terms'    => \$lang->term_id,
),
),
);



From there, it’s easy to build a form or whatever you want your plugin to do.

I know this is a bit off topic, but this information is unavailable anywhere. I nevertheless found that many plugin developers are getting stuck as I was.
