Well-targeted Buy One Get One promotions can attract more customers and encourage higher purchase volumes. If you own a furniture online store store where shipping costs are based on size, then you can implement such WooCommerce’s BOGO discount to target specific shipping classes and offer the free product.
Solution: Add BOGO (Buy One Get One) Offer based on Specific Shipping Classes in WooCommerce
The provided code snippet allows you to automatically add free products to the cart based on selected shipping classes.
function ts_aaptc_add_product_to_cart( $item_key, $product_id ) {
$shipping_class_ids = array( 'light_items', 'heavy-items' ); // Add more shipping class slugs here
$product_shipping_class = get_the_terms( $product_id, 'product_shipping_class' );
if ( ! is_admin() && ! empty( $product_shipping_class ) ) {
foreach ( $shipping_class_ids as $shipping_class ) {
foreach ( $product_shipping_class as $term ) {
if ( $term->slug === $shipping_class ) {
$free_product_id = 470; // Product Id of the free product which will get added to cart
$found = false;
// Check if product is already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $free_product_id ) {
$found = true;
break;
}
}
// If product not found, add it
if ( ! $found ) {
WC()->cart->add_to_cart( $free_product_id );
}
} else {
// If no products in cart, add it
WC()->cart->add_to_cart( $free_product_id );
}
break 2; // Break out
}
}
}
}
}
add_action( 'woocommerce_add_to_cart', 'ts_aaptc_add_product_to_cart', 10, 2 );
Output
When products from specific shipping classes are selected, a free gift can be provided as per your choice. In the below output since the free product ID is set in the code, this specific product gets automatically added to cart when products from specific shipping class’ heavy items’ and ‘light_items’ are added to the cart.
As we have seen with offering a free product based on shipping classes, you can also apply similar customizations based on a variety of conditions. For instance, you can automatically add products to your WooCommerce cart based on criteria such as product categories, cart total, or even specific actions like visiting a website.
