How to display extra fields in category.php was created by Uldis

Hello,

I noticed that there are some big changes for extra fields and that you can now output an extra field using -

$this->item->extraFields->EXTRAFIELDALIASHERE->value

, which is great.

But I would like to display extra field values in category.php.

For example:
I'm in category with 3 items.
Each item has an extra field with value a, value b, value c
On top of category (category.php) I would like to output - value a, value b, value c.

I'm trying to create a simple sorting solution.

I tried using this code - I found it in forum

<!-- Call to prepare extra field IDs --> 
          <?php 
     //convertArray to use ids as key
          $extrafieldsid = array();
          foreach($this->item->extra_fields as $itemid)
          {    
          $extrafieldsid[$itemid->id] = $itemid->value;
          }   
          ?>
<!-- Call to prepare extra field labels -->
           <?php 
     //convertArray to use labels as key
          $extrafieldslabels = array();
          foreach($this->item->extra_fields as $itemlabel)
          {    
          $extrafieldslabels[$itemlabel->id] = $itemlabel->name;
          }   
          ?>

and

<!-- Extra Fields -->
<div class="extrafield">
          <strong><?php echo $extrafieldslabels[1];?>: </strong><?php echo $extrafieldsid[1];?>
</div>
<div class="extrafield">
          <strong><?php echo $extrafieldslabels[2];?>: </strong><?php echo $extrafieldsid[2];?>
</div>
<div class="clr"></div>
 
<!-- End Extra Fields -->

But it seems that either I did something wrong or this code doesn't work with newer k2 versions.

Thank you both for replying.

Chris, your solution works great on category_item.php or item.php.

But I'm looking for a little bit different solution.

I will try to clarify.

Lets says I have category structure like this:
Fruit
|_Apples (with extra field color)
|_Oranges (with extra field color)

When I enter category Fruit I can display extra fields for each item within item (category_item.php), this is a k2 function.

But I would like to output a list of extra fields outside of item loop (category_item.php). I would like to output extra field values in category.php.

So in my example, at the top of category view I would have unordered list with - green (from apples extra field) and orange (from oranges extra field)
But I would like to output a list

Hi All, doing some hacking in a template over-ride of category.php, I am not a PHP programmer, so, need to keep that in mind please.

I have altered my category.php to display the list of articles in a table with the columns.

The first column goes the article name(works fine)
2nd column I want the location custom field
3rd column another value

Here is what I have tried, it is obviously wrong as all I get is repeats of the article name...

<?php
// Load category_item.php by default
$this->item->extraFields->Location->value;
echo $this->loadTemplate('item');
?>
What do I need to change, so that it actually outputs the value of the extra filed with the alias of "Location"?

Cheers
