Huge thanks to SideKick Dan for posting the original code!!!

Here is a copy of the final code I used.
Changes I made to the original code:
1. Changed the product category slug from ‘specials’ to ‘display’
2. Changed one of the users that could view the hidden prod. category from
‘customer’ to ‘wholesale_customer’
3. Removed ‘&& is_shop()’ from the if statement (this appears twice in the original code). The original code left the category visible in the woocommerce widget.

My revised Code.

// Woocommerce - Redirect unauthorised users from accessing a specified product category when clicked or visited via direct url

function woocommerce_hide_non_registered() {
 if( ( is_product_category('display') ) && ! ( current_user_can( 'wholesale_customer' ) || current_user_can( 'administrator' ) ) ) {
 wp_redirect( site_url( '/' ));
 exit();
 }
}
add_action( 'template_redirect','woocommerce_hide_non_registered' );
// End - Woocommerce - redirect unauthorised users from accessing a specified product category
// Woocommerce - Removes category link from woocommerce product category widgets so they are not seen
add_filter( 'get_terms', 'get_subcategory_terms', 10, 3 );
function get_subcategory_terms( $terms, $taxonomies, $args ) {
  $new_terms = array();
  // if a product category and on the shop page
  if ( in_array( 'product_cat', $taxonomies ) && ! ( current_user_can( 'wholesale_customer' ) || current_user_can( 'administrator' ) ) ) {
    foreach ( $terms as $key => $term ) {
      if ( ! in_array( $term->slug, array( 'display' ) ) ) {
        $new_terms[] = $term;
      }
    }
    $terms = $new_terms;
  }
  return $terms;
}
// End - Woocommerce - Removes category link from woocommerce product category widgets so they are not seen
// Woocommerce - Remove products from being displayed that belong to a category user is not authorised to visit. Products seem to still be accessible via direct url unfortunately.
add_action( 'pre_get_posts', 'custom_pre_get_posts' );
function custom_pre_get_posts( $q ) {
		if ( ! $q->is_main_query() ) return;
		if ( ! $q->is_post_type_archive() ) return;
		if ( ! ( current_user_can( 'wholesale_customer' ) || current_user_can( 'administrator' ) ) ) {
			   $q->set( 'tax_query', array(array(
				   'taxonomy' => 'product_cat',
				   'field' => 'slug',
				   'terms' => array( 'display'), // Don't display products in the private-clients category on the shop page
				   'operator' => 'NOT IN'
			   )));
		}
remove_action( 'pre_get_posts', 'custom_pre_get_posts_query' );
}
// End - Woocommerce - Remove products from being displayed that belong to a category user is not authorised to visit. Products seem to still be accessible via direct url unfortunately.

@jgoug:
I think it will work correctly if you assigned the few users into a specific user role such as “subscriber” or “author”

You might have to customize the user privileges to match your needs.

Hey Dan,

Thank you for posting this. This is exactly what I need but for some reason it does not seem to be hiding the category from the woocommerce product category widget. Any ideas?

-Category i’m trying to hide ‘display’
-I would like the Category ‘display’ to be visable only to ‘wholesale customer’ and ‘administrator’

-website link here

Here is the code I have.

// Woocommerce - Redirect unauthorised users from accessing a specified product category when clicked or visited via direct url

function woocommerce_hide_non_registered() {
 if( ( is_product_category('display') ) && ! ( current_user_can( 'wholesale customer' ) || current_user_can( 'administrator' ) ) ) {
 wp_redirect( site_url( '/' ));
 exit();
 }
}
add_action( 'template_redirect','woocommerce_hide_non_registered' );
// End - Woocommerce - redirect unauthorised users from accessing a specified product category
// Woocommerce - Removes category link from woocommerce product category widgets so they are not seen
add_filter( 'get_terms', 'get_subcategory_terms', 10, 3 );
function get_subcategory_terms( $terms, $taxonomies, $args ) {
  $new_terms = array();
  // if a product category and on the shop page
  if ( in_array( 'product_cat', $taxonomies ) && ! ( current_user_can( 'wholesale customer' ) || current_user_can( 'administrator' ) ) && is_shop() ) {
    foreach ( $terms as $key => $term ) {
      if ( ! in_array( $term->slug, array( 'display' ) ) ) {
        $new_terms[] = $term;
      }
    }
    $terms = $new_terms;
  }
  return $terms;
}
// End - Woocommerce - Removes category link from woocommerce product category widgets so they are not seen
// Woocommerce - Remove products from being displayed that belong to a category user is not authorised to visit. Products seem to still be accessible via direct url unfortunately.
add_action( 'pre_get_posts', 'custom_pre_get_posts' );
function custom_pre_get_posts( $q ) {
		if ( ! $q->is_main_query() ) return;
		if ( ! $q->is_post_type_archive() ) return;
		if ( ! ( current_user_can( 'wholesale customer' ) || current_user_can( 'administrator' ) ) && is_shop() ) {
			   $q->set( 'tax_query', array(array(
				   'taxonomy' => 'product_cat',
				   'field' => 'slug',
				   'terms' => array( 'display'), // Don't display products in the private-clients category on the shop page
				   'operator' => 'NOT IN'
			   )));
		}
remove_action( 'pre_get_posts', 'custom_pre_get_posts_query' );
