If we want to show the product attribute name for a variable or simple product on the cart page, you need to add the below code on your theme functions.php.
add_action('woocommerce_after_cart_item_name', 'wa_woocommerce_after_cart_item_name',10,2);
function wa_woocommerce_after_cart_item_name( $cart_item, $cart_item_key ){
$_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
$attributes = $_product->get_attributes();
if ( !empty( $attributes ) ) {
$attr_arr = [];
foreach( $attributes as $attr => $attr_val ) {
if ( isset( $attributes[ $attr ] ) || isset( $attributes[ 'pa_' . $attr ] ) ) {
$term_name = $_product->get_attribute( $attr );
if ( !empty( $term_name ) ) {
$attr_arr[] = $term_name;
}
}
}
}
if ( !empty( $attr_arr )) {
echo implode( ',', $attr_arr );
}
}
In my case, I added an attribute name after the product’s title using an action hook called woocommerce_after_cart_item_name.
