How to get Item's ExtraFields to display in latest.php of K2 - Joomla

Question

Im trying to get ExtraFields from K2 Articles. I have assigned my menu to Latest from Users or Categories in order to display all articles from several categories.

It displays fine. But these articles have ExtraFields information that I want to display, but there is no option to display ExtraFields, so I suppose that in order to do this I need to change latest.php page, which is the page used to display all articles from different Categories.

As latest.php doesn't display ExtraFields I'm trying to code it as the following:

<?php  
$extrafields = array();
foreach($this->item->extra_fields as $item)
{    
$extrafields[$item->id] = $item->value;
}   
?>    
<?php if(isset($extrafields[X]) === true):?>
<?php echo $extrafields[X]; ?>
<?php endif; ?>

Though, I'm getting the following error:

Invalid argument supplied for foreach() in ...

I've been searching ways to get ExtraFields, found some solutions but this is the error i get every time.

Any ideas or solutions?

Best regards.

I'm using joomla 2.5.

Answer 1

I just did it like this:

This code comes to the file latest_item.php:

<?php if (isset($this->item->extra_fields)) : ?>
  <div class="catItemExtraFields">
    <ul>
    <?php if (is_string($this->item->extra_fields)) {
        $this->item->extra_fields = json_decode($this->item->extra_fields);
      }
      foreach ($this->item->extra_fields as $key=>$extraField) {
        if ($extraField->value != '') {
          echo "<li>".$extraField->name.": ".$extraField->value."</li>";
        }
      }
    ?>
    </ul>
  </div>
<?php endif; ?>

You could do some more checking for existing members and so on.

Assuming you want to display data from the extra fields inside the latest.php, then :

Inside the appropriate foreach loop that goes through your content items and prints out each k2 item go as this:

<?php $extra = json_decode($item->extra_fields); ?>

$extra will be an array with the extra fields and their values.

<pre>
<?php print_r($extra); ?>
</pre>
