Reply To: Product taxonomy in asp_result_groups

The code seems to be incorrect. There is this knowledge base article on how to exactly use the asp_results_groups hook.

The main issue with your code is that you are tring to add items via query_posts to the live results list, however those are not compatible there. Instead of that, you should try ASP_Query. Something like:

$args = array(
	's' => '',
	'_ajax_search' => true,
	'post_tax_filter' => array(
		array(
			'taxonomy'  => 'product_cat',
			'include'   => array(123), // Taxonomy term ID here
			'allow_empty' => false // Allow results, that does not have connection with this taxonomy
		)
	)
);
$asp_query = new ASP_Query($args);
$groupss = $asp_query->posts;
