问题


How to sort items from a defined product category to be at the end of a cart order, for example I want all products that belong to a product category 'bottle' to be at the end of the cart order.

I have found this code that sorts by price, but would like to adjust to as described above.

add_action( 'woocommerce_cart_loaded_from_session', 'prefix_cart_order_prod_cat' );

function prefix_cart_order_prod_cat() {

    $products_in_cart = array();
    // Assign each product's price to its cart item key (to be used again later)
    foreach ( WC()->cart->cart_contents as $key => $item ) {
        $product = wc_get_product( $item['product_id'] );
        $products_in_cart[ $key ] = $product->get_price();
    }

    // SORTING - use one or the other two following lines:
    //asort( $products_in_cart ); // sort low to high
   arsort( $products_in_cart ); // sort high to low

    // Put sorted items back in cart
    $cart_contents = array();
    foreach ( $products_in_cart as $cart_key => $price ) {
       $cart_contents[ $cart_key ] = WC()->cart->cart_contents[ $cart_key ];
    }

    WC()->cart->cart_contents = $cart_contents;

}

You can use has_term() conditional WordPress function to check if cart items belongs to a product category (but the defined category(ies) need to be set for the related products (items)).

So the following code will sort cart items with items belonging to specified category(ies) at the end:

add_action( 'woocommerce_cart_loaded_from_session', 'product_category_cart_items_sorted_end' );
function product_category_cart_items_sorted_end() {
    $category_terms    = __('T-shirts'); // Here set your category terms (can be names, slugs or Ids)
    $items_in_category = $other_items = array(); // Initizlizing

    // Assign each item in a different array depending if it belongs to defined category terms or not
    foreach ( WC()->cart->cart_contents as $key => $item ) {
        if( has_term( $category_terms, 'product_cat', $item['product_id'] ) ) {
            $items_in_category[ $key ] = $item;
        } else {
            $other_items[ $key ] = $item;
        }
    }

    // Set back merged items arrays with the items that belongs to a category at the end
    WC()->cart->cart_contents = array_merge( $other_items, $items_in_category );
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.
