hi all I have the following problem.
I want to show the extra fields of the items related by tag.
$ this-> relatedItems is the array with related items and each item related have a data such as title, category, author, etc..(you can see in com_k2/item.php around line 461) I want to add the extra fields in these item data...
I can not find where are the parameters relatedItems to add the extra fields. I search
componets/com_k2/model/item.php
componets/com_k2/controller/item.php
thank you very much.

Hi,
I recently needed to do this for a clients website.
They needed the related items to be from another single category only, and needed a way to display the related items in a specific order.... (and not in the category list order, date order, alphabetical or item id or the reverse order of any of these!)
I only went as far as retrieving this specific extrafield from the array but the following might help you out, as it is all done in a template over ride - (so updates to K2 do not wipe out your changes) :


<?php if($this->item->params->get('itemRelated') && isset($this->relatedItems)): ?>

<?php //var_dump($this->relatedItems);
// Sort the data with volume descending, edition ascending["ordering"]
// Add $data as the last parameter, to sort by the common key
//$mynewOrder = array_multisort($item->id, SORT_ASC, $this->relatedItems);
//$mynewOrder = asort($this->relatedItems->item->id);
//$mynewOrder = array_multisort($item->id, SORT_ASC, $this->relatedItems);
//array_multisort($this->relatedItems,SORT_DESC );

?>
<?php
foreach ($this->relatedItems as $val)
{
$sortArrayRank[] = $val->ordering;
$MYvalobj[] = $val->extra_fields;
}

array_multisort(array_values($MYvalobj), $this->relatedItems);
?>

<!-- Related items by tag -->
<div class="itemRelated">
<h2>Testimonials</h2>
<ul>
<?php foreach($this->relatedItems as $key=>$item): ?>
<?php // if item not from category 4 check routine start ?>
<?php if($item->catid == 4): ?>
<li class="<?php echo ($key%2) ? "odd" : "even"; ?>">


<?php
$MYobj = $item->extra_fields;
$obj = json_decode($MYobj);

echo "<h1> ";
echo $obj[0]->value;
echo "</h1><br />";

?>
</li>
<li> ....</li>
etc....
<?php endif;// if item not from category 4 check end ?>
</ul>

Hope this helps point you in the right direction - I will be doing further work with this method and will post other changes.....

hi all ... mat thanks for reply .... i don't knew about json_decode now I have the extrafields of related item in an array but I still have a problem ...
the data in extra fields are $ extraField-> id, $ extraField-> value the problem is I need the extra field name not the id .... I was thinking to adding a new function in ITEMLIST model which can bring the names of extra fields but I can not display the data in the view does not really understand much that implements the mVC in k2
sorry for my english isn't my native language
thanks for the help! : D

Hi,
I just thought I would try this for you and it works!
Add the next bit of code inside the foreach($this->relatedItems as $key=>$item): part of the item.php template override file...


$MYobj = $item->extra_fields;
$obj = json_decode($MYobj);


$ItemExtrafieldID = $obj[0]->id;

$db = &JFactory::getDBO();
$query = "SELECT *".
" FROM #__k2_extra_fields";

$query .= " WHERE published = 1"
. " AND id = $ItemExtrafieldID";

$db->setQuery($query);
$data = $db->loadObjectlist();



echo "<h1>data->name = ";
echo $data[0]->name;
echo "</h1><br />";

Hope this helps....
Regards
Mat

​​thanks mat I'll try the code: D

thank you very much mat ... works but I think it isn't very advisable to add sql in the view and not respecting the MVC pattern that is why I had thought of adding sql queries in the corresponding model but my level of knowledge does not allow me. .. I will continue looking for ways to integrate in the mvc pattern ... here is the full code
