Hi!
This is only possible with a modification directly in the code. It might not work correctly, but it’s worth a try.
Open up the wp-content/plugins/ajax-search-pro/includes/views/asp.shortcode.categories_terms.php file and go to lines 124-128, where you should see this:
[php]$_needed_terms_full = get_terms($taxonomy, array(
‘orderby’ => $term_ordering[0],
‘order’ => $term_ordering[1],
‘include’ => $terms
));[/php]
change that code to this:
[php]$_needed_terms_full = get_terms($taxonomy, array(
‘orderby’ => $term_ordering[0],
‘order’ => $term_ordering[1]
));[/php]
This should get all the terms for a taxonomy, if at least one term is selected from the taxonomy.
