Canonical tag for add-to-cart

Hello,

Thank you for your query and we are so sorry about the trouble this must have caused.

I have modified the code a bit to include add-to-cart query URLs. Please refer to this code below:

add_filter('rank_math/frontend/robots', function ($robots) {
	$url = home_url($_SERVER['REQUEST_URI']);
	if ((strpos($url, '?add_to_wishlist=') !== false) || (strpos($url, '?add-to-cart=') !== false)) {
		$robots["index"] = 'noindex';
		$robots["follow"] = 'nofollow';
	}
	return $robots;
});

Hope that helps and please do not hesitate to let us know if you need my assistance with anything else.
