Display specific extra fields was created by boulder606

Hello,

i need to display specific extra fields. How can I do this? Would that be something like:

<?php echo $item->extra_fields[0]->value; ?>
<?php echo $item->extra_fields[1]->value; ?>

As well how would I be able to add different classes to each field?

Thanks

You can do it based on the alias:
github.com/kricore/Advanced-templating-with-K2/blob/master/_inc/cheatsheet.php#L104-L109

You can also add a <div> or a <span> with the class you want that wraps the field.

Thanks for the last reply but it seems I do something wrong

Here the code i used

<?php if($this->item->params->get('itemExtraFields') && count($this->item->extra_fields)): ?>
	  <!-- Item extra fields -->
	  <div class="itemExtraFields">
	  	  <!-- 	<h3><?php echo JText::_('K2_ADDITIONAL_INFO'); ?></h3> -->
	  		  <?php if($this->item->params->get('itemExtraFields') && count($this->item->extra_fields)): ?
 <?php if( isset( $this->item->extraFields->wxxx->value ) && ( $this->item->extraFields->wxxx->value ! == '') ) 
    {
	$this->item->extraFields->wxxx->name;
	$this->item->extraFields->wxxx->value;
     }
	  <?php endif; ?>
	    <div class="clr"></div>
	  </div>
	  <?php endif; ?>
	    <div class="clr"></div>
	  </div>
	  <?php endif; ?>

Error:

Parse error: syntax error, unexpected '!' in .......

You forgot to close the PHP brackets here:

$this->item->extraFields->wxxx->value;
     }

It should be:

$this->item->extraFields->wxxx->value;
     } ?>

Yes, I tried this :

// Render a specific extrafield
         <?php if ( isset( $this->item->extraFields->wxxx->value ) && ( $this->item->extraFields->wxxx->value ! == '') )
           {
          	$this->item->extraFields->wxxx->name;
        	$this->item->extraFields->wxxx->value;
            } ?>

still I get the error:

Parse error: syntax error, unexpected '!' in

Using the last version from K2 just in case you need to know

I worked it out. here the solution for someone who might want to do the same:

<?php if($this->item->extraFields->wlang->value != ''): ?>
<div class="itemExtraFieldswrapper">
<div class="itemExtraFieldsLabel"> <?php echo $this->item->extraFields->wlang->name; ?></div>
<div class="itemExtraFieldsValue"><?php echo $this->item->extraFields->wlang->value; ?></div>
</div>
<?php endif; ?>

that includes some div wrappers as well when you want to style them
