Hide Certain Products

Hi,

I am using WPLMS as a LMS solution which uses woocomerce to sell courses (as products). These courses are sold seperately and not through the shop page… so how can I hide them from appearing in the Woocommerce Shop page? Please guide….

will a code like the below work?

add_action(‘woocommerce_product_query’, function($q) {
$tax_query = (array) $q->get(‘tax_query’);
$tax_query[] = array(
‘taxonomy’ => ‘product_type’,
‘field’ => ‘slug’,
‘terms’ => array(‘? ? ?’), // Don’t display courses in shop page
‘operator’ => ‘NOT IN’
);
$q->set(‘tax_query’, $tax_query);
});

thanks in advance
