Another mod born from someone emailing and asking if an extension could be built with this functionality. The answer was of course yes and here it is.
It’s called Descriptive Text but that is somewhat inaccurate as this extension allows you to add any kind of content (that you normally can with the OpenCart editor), like videos, images and audio as well as text to key areas on the product page. The areas where content can be added are: Under Brands/Manufacturer, Under Price, Under Profiles, Under Options and Under Cart.
Content added to any of these areas will show in every product page. I think this will be particularly useful for imagery or video discussing payment options etc.
EDIT: There is now an extension that adds the same functionality as above but on a per product basis, if that’s what you need then check out our Extra Product Content extension.
