WooCommerce: How to Alter Cart Items Count

We’ve already seen how to exclude hidden products from the WooCommerce Mini-Cart widget counter; today I want to expand on the same concept and try to recalculate / alter such counter based on custom criteria.

For example, some business models require to count the number of distinct items in the Cart, no matter their respective cart quantities. So, if there are 2x “Item 1” and 4x “Item 2”, this altered counter would show 1+1=2 and not 2+4=6. So, let’s see how this is done – enjoy!

add_filter( 'woocommerce_cart_contents_count', 'tutoraspire_alter_cart_contents_count', 9999, 1 );

function tutoraspire_alter_cart_contents_count( $count ) {
$count = count( WC()->cart->get_cart() );
return $count;
}
