I'm studying the function zen_get_products_display_price($products_id)
that is called by the script
includes\templates\my_template\templates\tpl_product_info_display.php. and other.
I've seen that in admin I can choose to show a price with taxes included or not, by setting
DISPLAY_PRICE_WITH_TAX = 'true' or
DISPLAY_PRICE_WITH_TAX = 'false'
but I'm not able to understand how the function
detect the above setting and how for this works.
Is there some guru that is able to explain me that?
Thanks - Giovanni
