Returning the Value of an Extra_Field In category_item View was created by quebecguitare

Hello, thank you for reading this post.

I am trying to return the value of the extra_field_13 of an item, right in the header of the category_item view under the title.

This doesn't seems to work, I get an Invalid argument supplied for foreach.

Please help!

Regards

<header>
<?php if(isset($this->item->editLink)): ?>
<a class="catItemEditLink modal" rel="{handler:'iframe',size:{x:990,y:550}}" href="<?php echo $this->item->editLink; ?>"> <?php echo JText::_('K2_EDIT_ITEM'); ?> </a>
<?php endif; ?>
<h2>


<?php
//convertArray to use ids as key
$extrafields = array();
foreach($this->item->extra_fields as $item)
{
$extrafields[$item->id] = $item->value;
}
?>
<?php if ($this->item->params->get('catItemTitleLinked')): ?>
<a href="<?php echo $this->item->link; ?>"><?php echo $this->item->title; ?></a></br>
<a href="<?php echo $this->item->link; ?>"><?php echo $extrafields[13]; ?></a>
<?php else: ?>
<?php echo $this->item->title; ?>
<?php endif; ?>
<?php if($this->item->params->get('catItemFeaturedNotice') && $this->item->featured): ?>
<sup><?php echo JText::_('K2_FEATURED'); ?></sup>
<?php endif; ?>
</h2>
</header>

Thank you for your time!

You can render specific extrafields like this:

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

(Check where $item and $this->item has been used).

Hi qGuitare,

I have same problem.

It's not problem to see it on items but it's impossible on category_item.

You find solution?

Edit: And name work but value dosn't work. And i try with other template, i check if Extra fields are on.

Thank's.

Double check your category's settings to see if the extrafields are enabled.

I check it and extrafields are display. But i want to use it by myself. With value and name. To place url extrafields value on link of picture for example.

I try this:

 <?php echo $this->item->extraFields->test->name ;?><?php echo $extraField[4]->value;?><br/>
    <?php echo $this->item->extraFields->test->value ;?>
    <?php echo ($item->extraField->test->value); ?>
    <?php echo isset($item->extraFields->test->name); ?>
	
    
<?php    echo $this->item->extraFields->test->value; ?>
<?php echo  $item->extraFields->test->value; ?> 
 <?php echo $extrafields['4']->name; ?>

And i check with in on top:

$k2obj = new K2ModelItem(); $fields = $k2obj->getItemExtraFields($this->item->extra_fields, $this->item);

So all extra_fields name are show, but we can't see anything about value.

try

var_dump($this->item->extraFields->test);

Make sure you have not made a typo in the field's alias.

It appears that this field is present but it is empty (["value"]=> NULL).
Enter a value and try again. It also better if you check if the extrafield has a value before rendering it.

<?php if( isset($this->item->extraFields->test->value)): 
// echo the field
else: 
//no field echo sth else
endif;
?>
