Joomla K2 - 列出类别中所有文章的额外字段

I've many articles in a K2 category called "houses". Each article has an extra field called "address" and I need to show in a page this extra field for each article.

Something like this (a là Wordpress):

$houses = get_k2_articles_from_category('houses');
foreach ($houses as $house){
  echo $house->address;
}

Is it possible?

you have to override your k2 template

and add <?php echo $item->extraFields->YOUR_ALIAS_HERE->value; ?>
