Take this scenario:

K2 Extra fields: from-date, to-date, tax-rate.

Now for any single K2 item there will be multiple sets of these extra fields. But K2 item shows only 1 set of extra fields and no option to create its array.

While create a K2 item there is no option to create another set of the same extra fields for the same K2 item.

For example this is how i want (multiple sets of extra fields data for the K2 item)

from-date, to-date, tax-rate
2011 2012 4%
2012 2013 5%
2013 2014 5.5%

How can this be achieved? Any extension to K2 for some other way.

  • foreach($extrafields) << meaning the possibility of more than 1 ;)

  • Extra fields are stored in an Array. Now what i am talking about is an Array of Array of Extra Fields.... i want multiple SETS of the same extra fields... e.g. [{2011,2012,4},{2013,2014,5},{2014,2015,5.5}]

  • I'm not really sure what you're asking. Can you show an example of what the k2 extra fields would look like in the back end, and how you want it to be output?

I have just recently stumbled upon following extension http://www.joomreem.com/multiple-extra-fields-groups-mefg-for-k2.html . It is commercial, and they claim to solve just the problem of having multiple Extra Field Groups for a K2 item. Haven't tested it yet, though...


We have added multiple extra fields for K2. Extra fields can be applied to multiple extra field groups. The extra field groups can then be applied to multiple items or users.

At test version can be download from

Github download of k2 multiple extra fields

WARNING - this is only for testing purposes. It should only by used on a test/development site.


This exactly what the Datasets for K2 plugin does: http://www.joomreem.com/extensions-store/k2-datasets

Also, there is a documentation to learn in details how to use it: http://www.joomreem.com/documentation/item/58-joomreem-k2-datasets-user-manual.html

    I concur. I commissioned the development of this plugin at my old place of employment because we needed rows of field sets on each K2 item. It works :)
