Hello, everyone @k2 community,

to be honest I'm not that new to K2 itself - I have already build three sites with K2 integrated in the content. All of them work fine. However, I faced this problem the other night while trying to make K2 work with Joomfish. Had some problems with JoomFish not seeing K2 realted stuff but managed to sort that out after reading this post here: community.getk2.org/forum/topics/joomfish-and-k2-how-do-they I did exactly as Olivier Nolbert suggested:

Hi,
If you've installed JoomFish after K2, and don't want to make a full K2 update, just unzip the K2 zip install file in local and copy/upload all files under "/administrator/components/com_joomfish/contentelements" in the same directory on your website.
Olivier

After doing that I'm able to see and translate all things related to K2 (inc. K2 extra fileds, K2 categories, etc.) except K2 Items. That's a problem coz that's what I need to translate... After going to components/Joom!Fish/Translation in joomla admin and choosing the language and (Content elements) K2 Items from the drop-down menu I get the following error Fatal error: Call to undefined method translationFilter::translationFilter() in /home/angrupe/domains/iseta.lt/public_html/administrator/components/com_joomfish/contentelements/translationK2_categoryFilter.php on line 18. None of that happens when I choose for example K2 Categories from the same drop-down menus. Here's how the above mention php file looks like:

class translationK2_categoryFilter extends translationFilter {
function translationK2_categoryFilter($contentElement) {
$this->filterNullValue = -1;

$this->filterField = $contentElement->getFilter("K2_category");
parent::translationFilter($contentElement);
}

function _createFilter() {
$database = &JFactory::getDBO();
if (!$this->filterField)
return "";
$filter = "";
if ($this->filter_value != $this->filterNullValue) {
$sql = "SELECT tab.id FROM #__k2_items as tab WHERE tab.catid=$this->filter_value";
$database->setQuery($sql);
$ids = $database->loadObjectList();
$idstring = "";
foreach ($ids as $pid) {
if (strlen($idstring) > 0)
$idstring .= ",";
$idstring .= $pid->id;
}
$filter = "c.id IN($idstring)";
}
return $filter;
}

function _createfilterHTML() {
if (!$this->filterField)
return "";
$db = &JFactory::getDBO();
$categoryOptions = array();
$categoryOptions[] = JHTML::_('select.option', '-1', JText::_('K2_SELECT_CATEGORY'));

$sql = "SELECT DISTINCT p.id, p.name FROM #__k2_categories as p, #__".$this->tableName." as c WHERE c.".$this->filterField."=p.id ORDER BY p.name";
$db->setQuery($sql);
$cats = $db->loadObjectList();
$catcount = 0;
foreach ($cats as $cat) {
$categoryOptions[] = JHTML::_('select.option', $cat->id, $cat->name);
$catcount++;
}
$catnameList = array();
$catnameList["title"] = JText::_('K2_CATEGORIES');
$catnameList["html"] = JHTML::_('select.genericlist', $categoryOptions, 'catid_filter_value', 'class="inputbox" size="1" onchange="document.adminForm.submit();"', 'value', 'text', $this->filter_value);
return $catnameList;
}
}
?>

Line number 18 I think is function translationK2_categoryFilter($contentElement)


What could be the problem...?
I would really appreciate your help!

Please help

Hi,

You need to open the k2_items.xml and change:


<translationfilters>
<K2_category>catid</K2_category>
(...)

to

<translationfilters>
<K2_categories>catid</K2_categories>
(...)

Solved.

Thanks, Bruno! That really solved the problem!
Sorry for my late reply, though ;)

It's unbelievable that this post is a year old, and I still have to go and hack that file in K2 v.2.6.5! Or am I doing something wrong?
