   Custom cart item counts by product category in Woocommerce 3

   This function is made to display the cart count for a specific product category:

   function cat_cart_count( $cat_name ) {
       $count = 0; // Initializing
   
       // Loop through cart items
       foreach( WC()->cart->get_cart() as $cart_item ) {
           if( has_term( $term, 'product_cat', $cart_item['product_id'] ) )
               $count += $cart_item['quantity'];
       }
       // Returning category count
       return $count == 0 ? false : $count;
   }
   

   You will paste the code above to the function.php file of your active child theme or theme.

   For "shorts" category you will use it this way: cat_cart_count( "shorts" ) and will replace WC()->cart->get_cart_contents_count().

   Note: Since woocommerce 3, WC()->cart->get_cart_url(); is replaced by wc_get_cart_url().

   Customizing the snippet code with it for "tshirts" and "short" categories:

   <a class="cart-contents" href="<?php echo WC()->cart->get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php echo sprintf (_n( '%d t-shirt', '%d t-shirts', cat_cart_count( "tshirt" ) ), cat_cart_count( "tshirt" ) ); ?> - <?php echo sprintf (_n( '%d short', '%d shorts', cat_cart_count( "shorts" ) ), cat_cart_count( "shorts" ) ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>
   

   As the html tag class “cart-contents” is use by woocommerce refreshed cart fragments, you might need to rename it as explained in: Custom cart item counts by product category in Woocommerce 3

   Last thing in our customized snippet code, you can customize-it your way adding some text or additional things… I have replace "item(s)" by the category name.
