How to hide subcategory products from main category in Woocommerce?

In this tutorial; We will learn how to hide subcategory from main category page in woocommerce. To do this, We will need to create/add two products and assign them to parent and child categories.

I’ve assigned two products, one to the parent category i.e. category 1 and the other to the child category i.e. category 1-1.

Now after assigning products to the categories, if you’ll go to parent category page you’ll see both products from parent category as well as child category.

Now We want to display only parent category products and remove the child category products. Add the following lines of code at the end of your theme’s functions.php file.

function exclude_product_cat_children($wp_query) {
if ( isset ( $wp_query->query_vars['product_cat'] ) && $wp_query->is_main_query()) {
    $wp_query->set('tax_query', array( 
                                    array (
                                        'taxonomy' => 'product_cat',
                                        'field' => 'slug',
                                        'terms' => $wp_query->query_vars['product_cat'],
                                        'include_children' => false
                                    ) 
                                 )
    );
  }
}  
add_filter('pre_get_posts', 'exclude_product_cat_children');

Now if you’ll go to parent category page again or just refresh the page if you already are there you’ll see the products of child category being removed from here.

That is It.
