Why not use K2 Content and only display the extrafields?

My goal is to render an extra field from the current item into a module.

Hi All,

I think the K2 BNR Content module can be used for this purpose.

Either by using template overrides for the module, i.e to create a separate template override for each extra field you want to show, you need to replace the section of extra fields display of the module to show only one extra field by alias, then to select that template override in the proper module instance.

Or, by hacking the module to add a text field parameter to enter the field alias you want to show with this module instance.
This is a quick tutorial on how to display K2 extra field of the current item in a module position using BNR Content for K2

@Joe Campbell

Can you please clarify what exactly do you mean by "the current item"?

K2 content module cannot fetch the data of the current item page if this is what you mean.

Thanks @Lefteris

I wonder how/why @Nazmal is saying he can do it...

It would be ideal if the K2 Content Module could do it

@Joe Campbell

This is about displaying a specific extra field of the items fetched by the K2 content module (depending on the module settings) .

Can the K2 Content Module fetch the extra field JSON for the current page?

Now that I heard from @Lefteris that it can not be accomplished with the core K2 Content Module, I installed BNR Content for K2 and created an override — it works like a charm.

Note: if you not need apply conditions and just want to display extra fields of the current item, you can always uses the trusty Regular Labs Articles Anywhere extension with following code. Simply change the extra field ID:

{article k2:current}{extra-198}{/article}

Kudos buddy :)
