I am having trouble working with getCategoryIds() and would greatly appreciate help formulating this statement
$one = 71;
$two = 8;
$three = 4;
$categoryIds = $_product->getCategoryIds();
if(($one || $two || $three) is in $categoryIds)
{
do stuff;
}
I'm unsure of how to pull out all the categoryIds that a product might have (i.e. 5,7,2) and match against the hardcoded ones
