Joomla k2 component is power Joomla content system. k2 has a module that's called k2 content module and you can override the layout template of it.
I had this code for my k2 content module, this template file shows k2 items in 2 columns with even and odd classes and extra fields in it.
<?php
// no direct access
defined('_JEXEC') or die;
// includes placehold
$yt_temp = JFactory::getApplication()->getTemplate();
include (JPATH_BASE . '/templates/'.$yt_temp.'/includes/placehold.php');
?>
<div id="k2ModuleBox<?php echo $module->id; ?>" class="k2ItemsBlock<?php
if($params->get('moduleclass_sfx')) echo ' '.$params-
>get('moduleclass_sfx'); ?>">
<?php if($params->get('itemPreText')): ?>
<p class="modulePretext"><?php echo $params->get('itemPreText'); ?></p>
<?php endif; ?>
<?php if(count($items)): ?>
<ul class="product">
<?php foreach ($items as $key=>$item): ?>
<li class="<?php echo ($key%2) ? "odd" : "even"; if(count($items)==$key+1)
echo ' lastItem'; ?>">
<?php if($params->get('itemImage') || $params->get('itemIntroText')): ?>
<?php if($params->get('itemImage')): ?>
<div class="product-image">
<img src="<?php echo $item->image; ?>" alt="<?php echo
K2HelperUtilities::cleanHtml($item->title); ?>" />
</div>
<?php endif; ?>
<div class="main">
<?php if($params->get('itemTitle')): ?>
<p class="moduleItemTitle"><?php echo $item->title; ?></p>
<?php endif; ?>
<?php if($params->get('itemIntroText')): ?>
<div class="introtext">
<?php echo $item->introtext; ?>
</div>
<?php endif; ?>
<!-- end main-->
<?php if($params->get('itemExtraFields') && count($item->extra_fields)): ?
>
<div class="moduleItemExtraFields-energi">
<ul>
<?php foreach ($item->extra_fields as $extraField): ?>
<?php if($extraField->value != ''): ?>
<li class="type<?php echo ucfirst($extraField->type); ?>
group2">
<?php if($extraField->type == 'header'): ?>
<h4 class="moduleItemExtraFieldsHeader"><?php echo
$extraField->name; ?></h4>
<?php else: ?>
<span class="moduleItemExtraFieldsLabel"><?php echo
$extraField->name; ?></span>
<span class="moduleItemExtraFieldsValue"><?php echo
$extraField->value; ?></span>
<?php endif; ?>
<div class="clr"></div>
</li>
<?php endif; ?>
<?php endforeach; ?>
</ul>

I would like to show my articles in 3 columns with extra fields.
How to do this? If it's possible, help me to do it.
Thanks for your attention.
I am working with the following codes for Magento inside product page view.phtml.
<div class="manufacturer">
<?php if ($_product->getAttributeText('manufacturer') == "Bellazza" || "Della" || "Pet Zone" || "Spyder Auto" ):?>
<div class="dealer">
<p>Authorized Dealer:</p>
</div>
<div class="logoImg">
<?php echo $this->getLayout()->createBlock('manufacturer/manufacturer')->setProduct($_product)->setTemplate('manufacturer/product_manufacturer.phtml')->toHtml();?>
</div>
<?php elseif ?>
<?php endif;?>
</div>
So I create div.manufacturer to display associated brand logo image started by the title "Authorized Dealer". It works. But not all products have a brand so when I set the manufacturer attribute to empty ( refer to the image below ) I don't need the title "Authorized Dealer" anymore. What is the best practice to approach the elseif. Thank you
manufacturer/manufacturer.phtml
<?php
$maufacturers = Mage::getModel('manufacturer/manufacturer')->getCollection()->addFieldToFilter('status',Array('eq'=>1));
$_columnCount=4;
$i=0;
?>
<div class="manufacturer-list">
<?php foreach($maufacturers as $manufacturer): ?>
<?php if(Mage::getModel('eav/entity_attribute_source_table')->setAttribute(Mage::getModel('eav/entity_attribute')->load(Mage::getModel('eav/entity_attribute')->getIdByCode('catalog_product',"manufacturer")))->getOptionText($manufacturer->getMenufecturerName())): ?>
<?php if ($i++%$_columnCount==0): ?>
<ul>
<?php endif; ?>
<li>
<a href="<?php echo $this->getBaseUrl()."catalogsearch/advanced/result/?manufacturer[]=".$manufacturer->getMenufecturerName() ?>">
<?php echo $this->getLayout()->createBlock('core/template')->setmanufacturerimage($manufacturer->getFilename())->setlegend($manufacturer->getLegend())->setListPageFlag(1)->setTemplate('manufacturer/manufacturer_resize.phtml')->toHtml(); ?>
</a>
<div class="manufacturer-name">
<?php echo Mage::getModel('eav/entity_attribute_source_table')->setAttribute(Mage::getModel('eav/entity_attribute')->load(Mage::getModel('eav/entity_attribute')->getIdByCode('catalog_product',"manufacturer")))->getOptionText($manufacturer->getMenufecturerName()) ?>
</div>
</li>
<?php if ($i%$_columnCount==0 && $i!=count($maufacturers)): ?>
</ul>
<?php endif; ?>
<?php endif; ?>
<?php endforeach; ?>
</div>
product_manufacturer
<?php
$product=$this->getProduct();
if(Mage::getModel('eav/entity_attribute_source_table')->setAttribute(Mage::getModel('eav/entity_attribute')->load(Mage::getModel('eav/entity_attribute')->getIdByCode('catalog_product',"manufacturer")))->getOptionText($product->getData('manufacturer'))):
$manufacturers=Mage::getModel('manufacturer/manufacturer')->getCollection()->addFieldToFilter('menufecturer_name',$product->getData('manufacturer'));
foreach($manufacturers as $manufacturer){
$status=$manufacturer->getStatus();
if($status==1){
?>
<div class="manufacturer-img-box">
<a href="<?php echo $this->getBaseUrl()."catalogsearch/advanced/result/?manufacturer[]=".$manufacturer->getMenufecturerName() ?>">
<?php echo $this->getLayout()->createBlock('core/template')->setmanufacturerimage($manufacturer->getFilename())->setlegend($manufacturer->getLegend())->setTemplate('manufacturer/manufacturer_resize.phtml')->toHtml(); ?>
</a>
</div>
<?php }
}
endif;
?>
You need refactoring the code
<div class="manufacturer">
<div class="logoImg">
<?php echo $this->getLayout()->createBlock('manufacturer/manufacturer')->setProduct($_product)->setTemplate('manufacturer/product_manufacturer.phtml')->toHtml();?>
</div>
</div>
and check variable
<?php if(!is_null($manufacturer->getMenufecturerName())): ?>
<div class="manufacturer-name">
<?php
echo Mage::getModel('eav/entity_attribute_source_table')
->setAttribute(Mage::getModel('eav/entity_attribute')
->load(Mage::getModel('eav/entity_attribute')
->getIdByCode('catalog_product',"manufacturer")))
->getOptionText($manufacturer->getMenufecturerName())
?>
</div>
<?php endif; ?>
And you need refactoring your code. Because I loock much excess code in your template. You need get data in you block and in phtml you need render this data by API blocks. getImageSrc(); getManufactures() and more over methods for get processed information.

I'm having an issue using images from a Slideshow as links.
This is my code:
<div class="slider-wrapper theme-default sl-2">
<div id="slider-2" class="nivoSlider-2" >
<?php foreach ($items as $key=>$item): ?>
<?php if($params->get('itemImage') && isset($item->image)): ?>
<a class="moduleItemTitle" href="<?php echo $item->link; ?>">
<img src="<?php echo $path1;?>?src=<?php echo $item->image;?>&w=635&h=386&zc=1&q=100" alt="<?php echo K2HelperUtilities::cleanHtml($item->title); ?>" title="#htmlcaption<?php echo $key;?>"/>
</a>
<?php endif; ?>
<?php endforeach; ?>
</div>
<?php foreach ($items as $key=>$item): ?>
<div id="htmlcaption<?php echo $key;?>" class="nivo-html-caption">
<?php if($params->get('itemTitle')): ?>
<!--<h2><a class="moduleItemTitle" href="<?php echo $item->link; ?>"><?php echo $item->title; ?></a></h2>-->
<?php endif; ?>
<div class="clr"></div>
<?php if($params->get('itemIntroText')): ?>
<div class="description-slider2">
<p><?php echo $item->introtext; ?></p>
</div>
<?php endif; ?>
</div>
<?php endforeach; ?>
</div>
I pass through the "a" tag the $item->link parameter which returns these two strings since the slideshow only contains two images:
string(51) /demo-catarroja2/es/campanas/cavi-catarroja-virtual
&
string(49) /demo-catarroja2/es/campanas/plan-de-ayuda-social
If I inspect the element with a web browser it shows this:
<a class="moduleItemTitle" href="/demo-catarroja2/es/campanas/plan-de-ayuda-social">
<img src="http://complusoft.net/demo-catarroja2/templates/onews/html/thumb.php?src=/demo-catarroja2/media/k2/items/cache/9c2fe6cb8c357cf6d57c8926869c1003_XL.jpg&w=635&h=386&zc=1&q=100" alt="Plan de Ayuda social 2013" title="#htmlcaption1"/>
</a>
This image is obviously inside the a tag but its acting as a link, why could this be?
You can check out the site here:
The slideshow is on the main page up top.
Really need some help after many hours of banging head against a brick wall!
Basically I have a Joomla News page made in the K2 component. The page would have the top story, the next two, then the next four and the next four after that all with their own class so they can be styled differently for emphasis (like most news websites).
So there would be one row of one column - main news (with items image and text cut off after about 150 words with a 'read more')
second row - two columns - next two news pieces (with items image and text cut off after about 150 words with a 'read more')
third row - four columns - next four news pieces (with items image and text cut off after about 150 words with a 'read more')
fourth row - one column of eight links (no image just the title linked)

Like I say, I've tried and tried to make this template work, but have got nowhere!
You try it with wrong file! This file belongs to Filtrify Module!
You must:
set as template for category "default"
edit K2 native category settings,
edit K2 native category item settings,
edit K2 native
item settings,
After you set all native K2 parameters, you must clone your default k2 template. Do it so:
go into components/com_k2/templates.
Copy all, what you see, locally.
Then create in you templates/your-template/html folder named com_k2.
Copy into it all, what you got befor from components/com_k2/templates.
Then duplicate folder named "default" and give them own name. This will be your K2 template for overrides.
Then go into K2 administration and change template of you category, which you set up befor, from default to the new name. Just now you can begin with template overrides, but ONLY inside of templates/your template/html/com_k2/your-k2-template. The files you need to override are category-item.php for category view and item.php for single item view.
