@scharfet

What exactly are you trying to achieve? The extra fields are being displayed automatically since you have set up accordingly the category settings.

Hi!

The default method despays the extra fields in a simple table format.
But I want do display the extra fields as I need it.

For instance: I have 6 extrafields that are 3 questions and 3 answers which I would like to display in a slider as you can see here.
iteplus.es/marenostrum/index.php?option=com_k2&view=item&layout=item&id=1&Itemid=134#%C2%BFc%C3%B3mo-vemos-la-homeopat%C3%ADa-en-marenostrum

An other thng: I have an extra field which should be displayed in a div with different css styles (pink background)

I want to get this: estudiohr.com/clientes/marenostrum/03.html

What I want to ask is what is the correct way to add extra fields to a k2-template? (Not using the standard display of extra fields in a table.)

I hope I could explain myself clearly.

Thank you!

Hi William,
I have watched all the vidios on this page, but none of them are informing about extra fields and how to display them in a template.

Make a template override to item.php and then manipulate the output as you wish. Since you have specific styles for specific fields you may need to target your fields by using their id.

New website:

Hello,

I tried to add extra fields to a certain position in K2 item view in a new website.

What I did:
1.) In the Category-settings: the correct extra fields group is associated (Associated "Extra Fields Group")

2.) I added this code to item.php

Scharfet,

Try it without the single quotes around the IDs, like this - [1] - instead of this - .

This works for me, except the tabs don't render for me.

Hi Poe,

it is working now. You were right the code had errors.

For others who wants to know how to use "Extra Fields" in a personalized way in "Item view".
In "Category" > "Item View Options " > "Extra Fields" > it is necesary to choose "Show".
The extra fields will be displayed also in the standard way (in a table). This code need to be deleted forom item.php.

At the beginning of the item.php place following code.

I can get this to work in category.php but only at the end of the code. I want the extrafields to appear after the subcategories and before the items.

The first screen shot shows the code working after the item list:

The second screenshot shows the same code in the same category.php file but the extrafields are not showing:

I can't figure out why the same code will not work in a different location.

Hi there,

I'm using this part of php code in my template. So I have title and subtitle (extra fields) in my k2 items.

I'd like to use it in this way:

Every item has a title and I want to display it on home page. So when user click on the main page and open k2 item, I'd like that he would see a subtitle from extra fields instead of item title. But when item has no subtitle (extra fields), he would see item title....

Maybe someone help..

You will need to modify the item.php subtemplate in K2.

First read this on K2 templating in general: getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates

Then edit your item.php file and locate the part where the title is shown. We'll add a small check so we can display the subtitle instead.

Create your subtitle extra field, add it to a group and make sure this group is also assigned to one or more categories in K2. Let's say this extra field is simply called "Subtitle" in which case, it will get the alias "Subtitle" as well. We will use this "alias" to directly fetch and display the subtitle value if it exists.

Find this (~line 54):

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

and replace with this:

<?php if($this->item->extraFields->Subtitle->value!=''): ?>
<?php echo $this->item->extraFields->Subtitle->value; ?>
<?php else: ?>
<?php echo $this->item->title; ?>
<?php endif; ?>

This will check if the Subtitle extra field is set. If it is, it will display it, otherwise it will display the K2 item title.

Simple.

For more on this neat trick read the 2.6.2 release post: getk2.org/blog/1068-k2-v262-now-available

Hi :)

Only one question...

Code works perfectly, but now when we have subtitle (extrafields), so it displays on the item title position (that's OK) and also on the extra fields.

Maybe someone know, how to display this subtitle (extrafield) on item title and at the same time not display in the extra fields position...

This is extra field code from item php:

<?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($extraField->value != ''): ?>
			<li class="<?php echo ($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; ?>
			</ul>
	    <div class="clr"></div>
	  </div>
	  <?php endif; ?>

Under the foreach loop in PHP, do this (I'm only editing what's necessary - adapt as you wish):

<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>

<?php if($extraField->name=='Subtitle') continue; ?>
...
<?php endforeach; ?>

This will cause the foreach loop to skip when it comes to a "Subtitle" extra field. ;)

	  	<ul>
			

<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
<?php if($extraField->name=='Podtytul') continue; ?>
<?php endforeach; ?>




			
			<?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>
