Retrieve if a product has related or options

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5

From the show_default.php view I want ot check if the product has

more than zero related products assigned
more than zero options assigned.

i don't want to show them not load any content module but to activate something in the case it is true there is at least one product as related or as option.

what would be the code to check this?

I tried with this some kind of invention starting from the development guide

	$show_related = 0;
	$related_productClass = hikashop_get('class.product');
	$show_related=$related_productClass->get($product_related);

if (!empty ($this->element->options)) {  code to execute}
