@websteem that’s pretty much the same code I gave you!
Are you adding the code to your functions file?
You can add code to the archive-product.php template, it won’t be the code supplied though as you asked to use the woocommerce hooks.
If you want to add direct to the template, just use:
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;
}
