I am using Joomla! K2 v2.4.1 component on Joomla! v1.5.23. I want to display latest items by category in the item view page, the category being the current one which the current viewed item belongs to.
There are modules which I can use to display most recent items by category but I want to modify item.php and other related files (actually I don't know which files to edit except the item.php template file) to accommodate this requirement. Is it possible to achieve this? If yes, which files do I need to edit and with what code?
Given below is what I think is used to retrieve latest items by category.
class K2ViewLatest extends JView {
function display($tpl = null) {
$mainframe = &JFactory::getApplication();
$params = &JComponentHelper::getParams('com_k2');
$user = &JFactory::getUser();
$cache = &JFactory::getCache('com_k2_extended');
$limit = $params->get('latestItemsLimit',3);
$limitstart = JRequest::getInt('limitstart');
$model = &$this->getModel('itemlist');
$itemModel = &$this->getModel('item');
if($params->get('source')){
$categoryIDs = $params->get('categoryIDs');
if(is_string($categoryIDs) && !empty($categoryIDs)){
$categoryIDs = array();
$categoryIDs[]=$params->get('categoryIDs');
}
$categories = array();
JTable::addIncludePath(JPATH_ADMINISTRATOR.DS.'components'.DS.'com_k2'.DS.'tables');
if(is_array($categoryIDs)){
foreach($categoryIDs as $categoryID){
$category = & JTable::getInstance('K2Category', 'Table');
$category->load($categoryID);
if ($category->published && ($category->access <= $user->get('aid', 0))) {
//Merge params
$cparams = new JParameter($category->params);
if ($cparams->get('inheritFrom')) {
$masterCategory = &JTable::getInstance('K2Category', 'Table');
$masterCategory->load($cparams->get('inheritFrom'));
$cparams = new JParameter($masterCategory->params);
}
$params->merge($cparams);
//Category image
if (! empty($category->image)) {
$category->image = JURI::root().'media/k2/categories/'.$category->image;
} else {
if ($params->get('catImageDefault')) {
$category->image = JURI::root().'components/com_k2/images/placeholder/category.png';
}
}
//Category plugins
$dispatcher = &JDispatcher::getInstance();
JPluginHelper::importPlugin('content');
$category->text = $category->description;
$dispatcher->trigger('onPrepareContent', array ( & $category, &$params, $limitstart));
$category->description = $category->text;
//Category K2 plugins
$category->event->K2CategoryDisplay = '';
JPluginHelper::importPlugin('k2');
$results = $dispatcher->trigger('onK2CategoryDisplay', array(&$category, &$params, $limitstart));
$category->event->K2CategoryDisplay = trim(implode("\n", $results));
$category->text = $category->description;
$dispatcher->trigger('onK2PrepareContent', array ( & $category, &$params, $limitstart));
$category->description = $category->text;
//Category link

$category->link = JRoute::_($link);
$category->feed = JRoute::_($link.'&format=feed');
JRequest::setVar('view', 'itemlist');

$category->name = htmlspecialchars($category->name, ENT_QUOTES);
$category->items = $model->getData('rdate');
JRequest::setVar('view', 'latest');
JRequest::setVar('task', '');
for ($i = 0; $i < sizeof($category->items); $i++) {
if ($user->guest){
$hits = $category->items[$i]->hits;
$category->items[$i]->hits = 0;
$category->items[$i] = $cache->call(array('K2ModelItem', 'prepareItem'), $category->items[$i], 'latest', '');
$category->items[$i]->hits = $hits;
}
else {

if(is_array($usersIDs)){
foreach($usersIDs as $userID){
$userObject = JFactory::getUser($userID);
if (!$userObject->block) {

}

}
}
}
$source = 'users';
$this->assignRef('blocks', $users);
}
//Look for template files in component folders
$this->_addPath('template', JPATH_COMPONENT.DS.'templates');
$this->_addPath('template', JPATH_COMPONENT.DS.'templates'.DS.'default');
//Look for overrides in template folder (K2 template structure)
$this->_addPath('template', JPATH_SITE.DS.'templates'.DS.$mainframe->getTemplate().DS.'html'.DS.'com_k2'.DS.'templates');
$this->_addPath('template', JPATH_SITE.DS.'templates'.DS.$mainframe->getTemplate().DS.'html'.DS.'com_k2'.DS.'templates'.DS.'default');

}
}
But this file is somehow used to retrieve items in using menu link. I am sorry if this is not the case.
