How to disable Cash on Delivery on some specific products in Woocommerce

Question

I want to disable Cash on Delivery(COD) for some products on my online shopping site.

Is it Possible?

Answer 1

To do this you have to use woocommerce_available_payment_gateways filter.

add_filter('woocommerce_available_payment_gateways', 'show_hide_cod', 10, 1);

function show_hide_cod($gateways)
{
    //list of product id to exclude COD
    $product_id_list = [12, 34];
    $items = WC()->cart->get_cart();
    foreach ($items as $item => $values)
    {
        $_product = $values['data']->post;
        if (in_array($_product->ID, $product_id_list))
        {
            unset($gateways['cod']);
        }
    }
    return $gateways;
}

Code goes in function.php file of your active child theme (or theme). Or also in any plugin php files.
Please Note: I have't tested this code.
