WC_Geolite_Integration::get_country_iso() sometimes returns null instead of an array, so this commit adds a check to account for that possibility before using the returned value. Doing this to prevent the following undefined index notice:
PHP Notice: Undefined index: country in wp-content/plugins/woocommerce/includes/class-wc-geolite-integration.php on line 60
Fixes#20594
The algorithm to add a list of product categories to the query that order products of a given category by price was including only first level sub-categories since PR #20391. This was happening because `get_terms()` when called with the argument `parent` will only return direct children. To fix this and get all children for a given product category, it was necessary to replace `parent` with the argument `child_of`. See #20554 for a more detailed description of the issue that this commit fixes.
Replace the usage of `// @codingStandardsIgnoreStart` and `// @codingStandardsIgnoreEnd` with `// phpcs:ignore WordPress.NamingConventions.ValidHookName.UseUnderscores` on WC_Gateway_Paypal_IPN_Handler::check_response(). Ignoring a single PHPCS rule is better than ignoring everything to protect the line against potential violations of the other rules.
Commit c7a3fd2 changed the logic to check if the refund is a full refund to use the strict equal operator (`===`) in the following line:
25be9fc13c/includes/gateways/paypal/includes/class-wc-gateway-paypal-ipn-handler.php (L295)
This change broke the comparison as `$order->get_total()` will return the value respecting the number of decimals after the decimal point set in the option `woocommerce_price_num_decimals` and `wc_format_decimal()`, when called without a second parameter, will not format the received value to use the same number of decimals set in `woocommerce_price_num_decimals`. To fix this issue, this commit passes `wc_get_price_decimals()` as the second parameter to `wc_format_decimal()`. This way both values will always have the same number of decimals and the comparison should work when handling a full refund.
