避免 WooCommerce 购物车中的虚拟和实体产品组合

Avoid virtual and physical products combination in WooCommerce cart

我已经搜索了很长时间,但似乎从未找到可能的解决方案。

有没有人看到 如何在一个 Woocommerce 购物车中只允许实体产品或虚拟产品的任何解决方案? 可能,当客户尝试添加组合时弹出通知虚拟和物理并不允许组合 - 或者确保组合不能出现在一个购物车中。

顺序中的组合总是导致错误..

请帮忙。

以下将避免在购物车中合并实物和虚拟产品:

// Check cart items and avoid add to cart
add_filter( 'woocommerce_add_to_cart_validation', 'filter_wc_add_to_cart_validation', 10, 3 );
function filter_wc_add_to_cart_validation( $passed, $product_id, $quantity ) {
    $is_virtual = $is_physical = false;
    $product = wc_get_product( $product_id );

    if( $product->is_virtual() ) {
        $is_virtual = true;
    } else {
        $is_physical = true;
    }

    // Loop though cart items
    foreach( WC()->cart->get_cart() as $cart_item ) {
        // Check for specific product categories
        if ( ( $cart_item['data']->is_virtual() && $is_physical )
        || ( ! $cart_item['data']->is_virtual() && $is_virtual ) ) {
            wc_add_notice( __( "You can't combine physical and virtual products together.", "woocommerce" ), 'error' );
            return false;
        }
    }

    return $passed;
}


// For security: check cart items and avoid checkout
add_action( 'woocommerce_check_cart_items', 'filter_wc_check_cart_items' );
function filter_wc_check_cart_items() {
    $cart = WC()->cart;
    $cart_items = $cart->get_cart();
    $has_virtual = $has_physical = false;

    // Loop though cart items
    foreach( WC()->cart->get_cart() as $cart_item ) {
        // Check for specific product categories
        if ( $cart_item['data']->is_virtual() ) {
            $has_virtual = true;
        } else {
            $has_physical = true;
        }
    }

    if ( $has_virtual && $has_physical ) {
        // Display an error notice (and avoid checkout)
        wc_add_notice( __( "You can't combine physical and virtual products together.", "woocommerce" ), 'error' );
    }
}
