Hi,
All product custom fields are stored in the "product" table and available in "product" objects.
And you just have to know the namekey of your custom field to access it in the object.
In views like "listing_price", you should have access to the current product thanks to " $this->row ".
Depending the context and the view it can also be available through " $this->element ".
