在WooCommerce商店页面中隐藏特定类别

Question

I have a shop page in WooCommerce, and i'm using this to override the "archive-product.php"

My goal was to display my categories in a nest, with a header above each product category. This achieves that, except I don't want all of the categories to be displayed. Ideally, 2 of my three product categories would be listed with the third one remaining hidden.

Honestly, I'm a graphic designer and most of my knowledge remains in CSS and HTML... so any help would be greatly appreciated.

Thanks!

Modifying

$product_categories = get_categories( array( 'taxonomy' => 'product_cat', 'child_of' => $parent_id) );

with:

$excludedCats = array(23,12,55); //Where 23,12 and 55 are category ids you want to leave out
$excludedCats = "23,12,55" //This works too

$product_categories = get_categories( array( 'taxonomy' => 'product_cat', 'child_of' => $parent_id, 'exclude' => $excludedCats) );

should do what you need. Sources: 1 , 2 and 3
