Hi Kuato,

unfortunately the code suggested on that link is only for putting inside K2 layouts, and it assumes that the $this->item object contains the K2 object so you can get the extra fields from it. When you are inside the PHP code of a module on the page, $this does not point to the same thing, so you'll need to get hold of $this->item->extrafields some other way.

One way to get this is to use the JomGenius K2 object, like this:

$k2 = JomGenius("k2");
$fields = $k2->info("item_extra_fields");
if ($fields != "") {
  $fields =  json_decode($fields);
  $extrafields = array();
  foreach($fields as $item) {
    $extrafields[$item->id] = $item->value;
  }
  // do something with the data here, e.g.
  echo $extrafields[0]; // where the index is the extra fields "id"
}


Hope that helps,
Stephen
