K2 | The powerful content extension for Joomla! developed by JoomlaWorks

To directly output individual extra fields in your K2 overrides, do something like this (e.g. in item.php) to get the extra field name:

echo $this->item->extraFields->EXTRAFIELD_ALIAS_HERE->name;

To get the extra field value you would simply do this: 

echo $this->item->extraFields->EXTRAFIELD_ALIAS_HERE->value;
echo $this->item->extraFields->EXTRAFIELD_ALIAS_HERE->rawValue; // for date type only

Simply replace EXTRAFIELD_ALIAS_HERE with the actual alias of the extra field you wish to output.

In modules, use:

echo $item->extraFields->EXTRAFIELD_ALIAS_HERE->value;
echo $item->extraFields->EXTRAFIELD_ALIAS_HERE->rawValue; // for date type only

CM K2 Inline is a Joomla! component helping you customize K2 component’s back-end item list and edit extra field inline.

K2 is the popular powerful content extension for Joomla with CCK-like (content construction kit) features. Every item of K2 can be extended by extra fields. If the most important part of your K2 content is extra fields then you would find it difficult to modify your K2 items. You need to go to item list, click an item, click Extra Fields tab, modify extra fields, save the item, go back to the list, click an item, and so on... It is also difficult for you to compare the extra field values of your K2 items. You can't open 10 browser tabs to check and compare 10 items.
