Uncaught Error: Call to a member function get_meta() on false

Hello,

I’m the developer of https://ww.wp.xz.cn/plugins/tax-switch-for-woocommerce/. One of our users reported a conflict between our plugins that I’ve investigated.

The issue happens when the Tax Switch plugin creates a temporary WooCommerce product object for price calculations:

$calculator = new WC_Product_Simple();

This eventually triggers your <code class=”bg-text-200/5 border border-0.5 border-border-300 text-danger-000 whitespace-pre-wrap rounded-[0.3rem] px-1 py-px text-[0.9rem]”>elex_rp_get_adjustment_for_individual_products() method in <code class=”bg-text-200/5 border border-0.5 border-border-300 text-danger-000 whitespace-pre-wrap rounded-[0.3rem] px-1 py-px text-[0.9rem]”>Elex_Price_Discount_Admin. The problem occurs on line 791 where:

$product = wc_get_product($pid);
$product_price_adjustment_users = $product->get_meta('product_price_adjustment_for_users');

For temporary product objects, wc_get_product($pid) returns false, causing a PHP error when trying to call get_meta() on a non-object. Could you add this check before accessing the product’s meta data?

if (!$product || !is_object($product)) { return 'no_amount'; }

This would fix the compatibility issue between our plugins.

Thank you in advance!
