Woocommerce upsell с флажками

У меня возникла проблема с новым разделом upsell, который я добавил для сайта wordpress/woocommerce.

Upsells красиво отображаются на странице продукта и могут быть добавлены в корзину, но идентификаторы продукта прикрепляются после этикетки.

Пожалуйста, смотрите прилагаемые фотографии;

Код, который я использую;

Функции.php

    function add_upsells_to_cart( $cart_item_key ) {

    global $woocommerce;



    if ( empty( $_REQUEST['upsells'] ) || ! is_array( $_REQUEST['upsells'] ) )

        return;



    // Prevent loop

    $upsells = $_REQUEST['upsells'];

    unset( $_REQUEST['upsells'] );



    // Append each upsells to product in cart

    foreach( $upsells as $upsell_id ) {

        $upsell_id = absint( $upsell_id );



        // Add upsell into cart and set upsell_of as extra key with parent product item id

        $woocommerce->cart->add_to_cart( $upsell_id, 1, '', '', array( 'upsell_of' => $cart_item_key ) );

    }

}

add_action( 'woocommerce_add_to_cart', 'add_upsells_to_cart', 1, 6 );

    if ( array_key_exists( 'upsell_of', $values ) )

        $item[ 'upsell_of' ] = $values['upsell_of'];



    return $item;
