Warning forech() was created by Patryk Szczepański

Hi, i have Joomla! 3.2.0 and K2 2.6.7.
In category_item.php i add code:
$extrafieldslabels = array();
foreach($this->item->extra_fields as $itemlabel);
{
$extrafieldslabels[$itemlabel->id] = $itemlabel->name;
}

And in code site add:
<?php if ($$itemlabel[1] != "") {echo $itemlabel[1];}?>

but i have error:
Warning: Invalid argument supplied for foreach() in /enklawa/templates/enklawa/html/com_k2/mieszkania/category_item.php on line 17

In item.php it's all ok in the same code.

Why? Please help.

Sorry byt my english is not well.

The $$itemlabel[1] != "" is a typo, you meant $itemlabel, you probably have it correctly in your code as well.

I can also see a trailing semilcolon in the foreach statement. probably another typo as well.

Finally I think this code is not needed.

You can direclty render extrafields or you can implement the check in the default extrafields loop.

I can see two typos.

Also I told you this code is not really necessary. You can use the default extrafields loop code.

<?php
//convertArray to use ids as key
$extrafields = array();
foreach($this->item->extra_fields as $item)
{
$extrafields[$item->id] = $item->value;
}
?>

This is it?

			<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
			<?php if($extraField->value != ''): ?>
			<li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
				<?php if($extraField->type == 'header'): ?>
				<h4 class="itemExtraFieldsHeader"><?php echo $extraField->name; ?></h4>
				<?php else: ?>
				<span class="itemExtraFieldsLabel"><?php echo $extraField->name; ?>:</span>
				<span class="itemExtraFieldsValue"><?php echo $extraField->value; ?></span>
				<?php endif; ?>
			</li>
			<?php endif; ?>
			<?php endforeach; ?>

This is the default loop in item.php. You can safely adapt this loop to match your needs.

If you only want this then directly render that extrafield.
