您可以使用WC_Cart $cart_id方法在购物车中找到商品。您需要使用find_product_in_cart()生成$product_id = 123456; // Some product id $product_cart_id = WC()->cart->generate_cart_id( $product_id ); // Returns an empty string, if the cart item is not found $in_cart = WC()->cart->find_product_in_cart( $product_cart_id ); if ( $in_cart ) { // Do something if the product is in the cart } else { // Do something if the product is not in the cart } ，以便执行此操作：
