我在为wordpress/woocommerce网站添加的新的追加销售部分遇到了问题.

加售在产品页面上很好地显示并且可以添加到购物车中,但产品ID在标签后附加.

请参阅附图;

我正在使用的代码;

的functions.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 ) );
    } …
