Try this first to call a single extra field anywhere: getk2.org/documentation/tips-a-tricks/2667-display-single-extra-fields-anywhere-in-your-k2-content

This applies to both item.php and category_item.php.

I did not really get the "spam block" comment you made.

my website is : automaz.fu2018.e-kei.pl/index.php/k2



If I have field with alias: Cena
I must change

echo $this->item->extraFields->EXTRAFIELD_ALIAS_HERE->name; to
echo $this->item->extraFields->Cena->name;
or
echo $this->item->extraFields->CENA->name; ?

so, If I have in category_item.php :
<?php if($this->item->params->get('catItemTitle')): ?>
<!-- Item title -->
<h3 class="catItemTitle">
<?php if(isset($this->item->editLink)): ?>
<!-- Item edit link -->

<span class="catItemEditLink">
<a data-k2-modal="edit" href="<?php echo $this->item->editLink; ?>">
<?php echo JText::_('K2_EDIT_ITEM'); ?>
</a>
</span>
<?php endif; ?>

<?php if ($this->item->params->get('catItemTitleLinked')): ?>
<a href="<?php echo $this->item->link; ?>">
<?php echo $this->item->title; ?>
</a>

<?php else: ?>
<?php echo $this->item->title; ?>

<?php endif; ?>
<?php echo $this->item->extraFields->CENA->name;?><?php echo $this->item->extraFields->CENA->value;?>
<?php echo $extrafields[8];?> zł <?php echo $this->item->extraFields->CENA->value;?>

I don't see price on title

2.
How to hide extra fields Cena from additional information on
automaz.fu2018.e-kei.pl/index.php/k2/item/1-renaultscenic
?
I try this : gavick.com/blog/how-to-hide-selected-k2-extra-fields-from-the-front-end
and I don't see effects.

Make the "alias" lowercase and call it like that:

echo $this->item->extraFields->cena->name; (for the name - Cena)
echo $this->item->extraFields->cena->value; (for the actual value, the price)

To hide a specific extra field from the extra fields loop, you need to add an exception there. E.g. in the current item.php file as seen here github.com/getk2/k2/blob/master/components/com_k2/templates/default/item.php#L250 you would change "<?php if($extraField->value != ''): ?>" to "<?php if($extraField->value != '' || $extraField->name != 'Cena'): ?>".

Thanks for reply, Show extrafields in title works ok! :) but hide someone extrafield no...

I change alias to lowercase and change :

<?php if($extraField->value != ''): ?> to <?php if($extraField->value != '' || $extraField->name != 'cena'): ?> but field cena is still show. Cena 17900
site automaz.fu2018.e-kei.pl/index.php/item/4-skoda-octavia

item.php looks now:
<?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>
<ul>
<?php foreach ($this->item->extra_fields as $key => $extraField): ?>
<?php if($extraField->value != '' || $extraField->name != 'cena'): ?>

<li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?> alias<?php echo ucfirst($extraField->alias); ?>">
<?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; ?>
</ul>
<div class="clr"></div>
</div>
<?php endif; ?>

Replace:
<?php if($extraField->value != '' || $extraField->name != 'cena'): ?>

with:
<?php if($extraField->value != '' && $extraField->name != 'cena'): ?>
