k2 related items in category_item.php was created by jim

I have the following code which I use within the k2 template file 'item.php'

<?php echo $this->relatedItems[0]->title->value ;?>

Id simply like to use this same code in the k2 template file 'category_item.php'

Ive found the function 'getRelatedItems' in components/com_k2/models/itemlist.php and copied this to components/com_k2/models/item.php but this hasn't helped.

If anyone has any ideas, id really appreciate it thanks!

Hacking the core is not recommended and can lead to unexpected errors.
The related items are not available in the itemlist views.
I would suggest using an extension or a K2 plugin instead.

Hi Krikor,
Many thanks for your reply/help!

Could you possibly suggest an extension/k2 plugin that might do the trick? Ive looked but haven't found anything.

Basically, what im aiming to achieve is, simply a count (only the integer) of related items on each item on category view.

Many thanks in advance!

I can recommend RAXO Related K2 Items module which is specially designed to show related content for K2.

Description from the site:
RAXO Related K2 Items is a convenient module that automatically shows a list of K2 items related to the current entry, introducing your reader to the relevant content from around your K2 site. Be sure that every occasional visitor from Google gets enough interesting items to read and stay on your site forever.
RAXO Related K2 Items suggests various ways to find related content – by keywords, by tags, by author or by category. So you can be sure that every of your K2 items will get attention. This functional module is able to find the match for every single item to keep your reader engaged and increase your page views.

Hello Alex,

If it can be triggered in category views then it will fit Jim.

@Krikor, many thanks, could you possibly clarify what you mean by triggered in category view, yes this is what i need I believe just simply the get related items function in the relevant file.

@Alex, many thanks, although that module is quite expensive at 25$ and im unsure/doubtful at this stage if it will provide the very simple count of related items for each item on category view

@jim
Hmmm, it looks like I got your task not correctly.
This module doesn't show up on category pages, only on K2 item pages.
So no, it won't fit you.

You have to copy the related functions from the items model like you did.

The you would have to copy the code from the item.php to the category_item.php.

Keep in mind that depending on the context $item and $this->item might be used.

Hello,

I have tried to make the hack as minimal as possible, here is it:

Edit components/com_k2/views/itemlist/view.html.php, find this code snippet:

else
			{
				$items[$i] = $model->prepareItem($items[$i], $view, $task);
			}

Insert this snippet directly after the above one:

if (isset($items[$i]->tags) && count($items[$i]->tags))
			{
				$itemListModel = $this->getModel('itemlist');
				$items[$i]->relatedItems = count($itemListModel->getRelatedItems($items[$i]->id, $items[$i]->tags, $items[$i]->params));
			}

Then you can use this line anywhere in category_item.php to display the related items count

<?php if(isset($this->item->relatedItems)) { echo " Related Items(" .$this->item->relatedItems . ")"; } ?>

Hi jim,
Do you find any error? If yes, what is the message?
Also make sure the related items parameter is set to Show in the category configuration.

Hi Mohamed,
Thanks again for this, much appreciated!!! :)

Sorry I should have turned on error reporting and included this error in my previous post (sorry about that!) here is the error:

Undefined property: stdClass::$relatedItems in <b>/templates/my-template/html/com_k2/templates/properties/category_item.php</b> on line <b>25

Also yes the related items parameter is set to show and related iems are being displayed on the single items pages.

Once again thanks so much for your time and help on this Mohamed!!! Really really appreciate it!!! :)

Hi Jim,

I have it already working on my local website!
As long as you applied the modifications as described, I think it is a configuration issue, all relevant Related Items parameters have to be set to Show.
