Hide/Exclude a category from WooCommerce Shop page

I found this article: http://www.wptaskforce.com/how-to-exclude-one-or-more-category-in-woocommerce-shop-page/

Basically you need to insert it at the bottom of functions.php. Then replace

'field' => 'slug',

'terms' => array( 'PUT YOUR CATEGORY HERE' ), // Don't display products in the m

with

'field' => 'id',

'terms' => array(20,25), // Don't display products in the m

and instead of 20, 25 insert the category id(s) you want to exclude. Separate them with a comma.

Not sure why it doesn’t work in your case. I tested it with

add_action( 'pre_get_posts', 'custom_pre_get_posts_query' );

function custom_pre_get_posts_query( $q )

{



if (!$q->is_main_query() || !is_shop()) return;

if ( ! is_admin() )

{

$q->set( 'tax_query', array(array(

'taxonomy' => 'product_cat',

'field' => 'id',

'terms' => array( 57 ),

'operator' => 'NOT IN'

)));



}

}

(57 is the id of the category I excluded) and it worked for me. If it doesn’t work try to deactivate all third party plugins/extensions except WooCommerce – maybe another plugin hooks into the query and breaks it.
