Show a k2 extrafield for current article

Show a k2 extrafield for current article

Hello, thanks in advance for your time. I'm trying to display a k2 extrafield content on a module using  metamod. So far i've managed to show metamod just on k2 items using.

Code:

if ($option == "com_k2" and $view == "item")

Now i need to get the, for example, content of the extrafield named "map" for the k2 article i'm reading and show it in the metamod module, I've followed the instructions suggested here http://jbeginner.com/tutorials/extensio … ra-fields/  and added if

Code:

($option == "com_k2" and $view == "item")  echo $extrafields[4];

but the result is the same content for every article, even if the extra field content is different. Any idea?

Re: Show a k2 extrafield for current article

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
