我正在使用Joomla！ Joomla上的K2 v2.4.1组件！ v1.5.23。我想在项目查看页面中按类别显示最新的项目，该类别是当前查看项目所属的当前项目。在K2组件的项目查看页面中添加“分类最新项目”块
有我可以用来按类别显示最新项目的模块，但我想修改item.php和其他相关文件（实际上我不知道除了item.php模板文件之外要编辑哪些文件）到满足这个要求。是否有可能实现这一目标？如果是的话，我需要编辑哪些文件以及使用哪些代码？
以下给出了我认为用于按类别检索最新项目的内容。
class K2ViewLatest extends JView {
function display($tpl = null) {
$mainframe = &JFactory::getApplication();
$params = &JComponentHelper::getParams('com_k2');

$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);

但是这个文件在某种程度上用于检索使用菜单链接中的项目。如果情况并非如此，我很抱歉。
任何人plz。我被困在这段代码中。 – 2012-02-02 14:33:33
