Hi @websteem
Odd, if you use the below, what do you see?
add_action( 'woocommerce_after_main_content', 'my_extra_description' );
function my_extra_description() {
global $wp_query;
# get the query object
$category = $wp_query->get_queried_object();
#get the cat ID
$category_ID = $category->term_id;
echo '<p>Can we see this? Is '.$category_ID.' the right ID for this category?</p>'; #remove after debug
#get the field
$contenu_categorie = get_field( 'contenu_categorie', 'category_'.$category_ID );
#if we have data, show it
if( $contenu_categorie ){
echo $contenu_categorie;
}
}
I’ve just tested the above with your field name on the twenty-twentyone theme and worked
