I'm not sure if this is completely related --

I have added some extra fields to an existing item using the Joomla CMS, but am having trouble figuring out where to make these values appear on the frontend. Where is the PHP/HTML template that controls the frontend page? Here is an example product page on the website I'm supporting: www.exmweb.com/index.php?option=com_k2&view=item&id=147:es-standard-door&Itemid=533&lang=en

(I'm sorry if this is an ignorant question -- I don't usually work in Joomla.)

This link ->
www.exmweb.com/index.php?option=com_k2&view=item&id=147:es-standard-door&Itemid=533&lang=en&template=system

uses the default template shows the extrafields. This means that you need to download K2 and compare the default item.php's code to your overrides. The code is well commented so you won't have issue locating the extra fields block.

In order to locate the files you need to edit you need to read this post getk2.org/documentation/tutorials/174
