如何针对特定产品隐藏 WooCommerce 的优惠券字段？

Question

我正在尝试在WooCommerce购物车和结账页面中隐藏某些产品的优惠券字段。在谷歌上搜索后，我找到了一些代码可以隐藏优惠券字段，但只适用于一个产品。

我该如何在这段代码中处理多个产品：

// hide coupon field on the checkout page
function disable_coupon_field_on_checkout( $enabled ) {
    if ( is_checkout() ) {
 
        $product_id = 240790;
        $in_cart = false;
        
        foreach( WC()->cart->get_cart() as $cart_item ) {
           $product_in_cart = $cart_item['product_id'];
 
           if ( $product_in_cart === $product_id ) $in_cart = true;
        }
 
        if ( $in_cart === true )
        {
            $enabled = false;
        }
    }
    return $enabled;
}
add_filter( 'woocommerce_coupons_enabled', 'disable_coupon_field_on_checkout' );
 
// hide coupon field on the cart page
function disable_coupon_field_on_cart( $enabled ) {
    if ( is_cart() ) {
        $product_id = 240790;
        $in_cart = false;
        
        foreach( WC()->cart->get_cart() as $cart_item ) {
           $product_in_cart = $cart_item['product_id'];
 
           if ( $product_in_cart === $product_id ) $in_cart = true;
        }
 
        if ( $in_cart === true )
        {
            $enabled = false;
        }
    }
    return $enabled;
}
add_filter( 'woocommerce_coupons_enabled', 'disable_coupon_field_on_cart' );

下面的代码将处理多个产品ID和/或变体ID，用于购物车和结账页面，禁用这些产品的优惠券字段。

// hide coupon field on cart and checkout pages
add_filter( 'woocommerce_coupons_enabled', 'disable_coupon_field_for_specific_products' );
function disable_coupon_field_for_specific_products( $enabled ) {
    if ( ( is_checkout() && !is_wc_endpoint_url() ) || is_cart() ) {
        // here define your product IDs in the array
        $product_ids = array(240790, 240792, 240795, 240798);
        
        // Loop through cart items
        foreach( WC()->cart->get_cart() as $item ) {
            if ( count( array_intersect( [$item['product_id'], $item['variation_id']], $product_ids ) ) > 0 ) {
                return false;
            }
        }
    }
    return $enabled;
}
