我在 Joomla 2.5 中使用 Module minifrontpage。网址在这里: http: //www.bigideaadv.com/wright_flood_OLD/
我要做的是检索 4 篇最新文章。2 个来自一个类别,2 个来自另一个类别。并且顺序需要是第1类文章,然后是第2类文章(我已经设置了,只是无法获得每个类别的限制。)
任何帮助,将不胜感激。谢谢。
我的数据库功能代码如下:
// Get the dbo
$database = JFactory::getDbo();
//Get the config
$config =& JFactory::getConfig();
$user =& JFactory::getUser();
$tzoffset = $config->getValue('config.offset');
// Get an instance of the generic articles model
$model = JModel::getInstance('Articles', 'ContentModel', array('ignore_request' => true));
// Set application parameters in model
$app = JFactory::getApplication();
$appParams = $app->getParams();
$model->setState('params', $appParams);
// Get Module Parameters
$number_of_article = (int) $params->get('number_of_article', 5);
$order = $params->get( 'order_by', 1);
$order_type = $params->get( 'order_type', 'asc');
$period = intval( $params->get( 'period', 366 ) );
echo "ORDER: ".$order."<br />";
//echo "ORDER BY: ".$order_by;
//$query2 = "SELECT * FROM ()"
// Set the filters based on the module params
$model->setState('list.start', (int) $params->get('number_of_skip', 0));
$model->setState('list.limit', (int) $params->get('number_of_article', 5));
$model->setState('filter.published', 1);
// Access filter
$access = !JComponentHelper::getParams('com_content')->get('show_noauth');
$authorised = JAccess::getAuthorisedViewLevels(JFactory::getUser()->get('id'));
$model->setState('filter.access', $access);
// Category filter
$model->setState('filter.category_id', $params->get('catid', array()));
// User filter
$userId = JFactory::getUser()->get('id');
switch ($params->get('user_id'))
{
case 'by_me':
$model->setState('filter.author_id', (int) $userId);
break;
case 'not_me':
$model->setState('filter.author_id', $userId);
$model->setState('filter.author_id.include', false);
break;
case '0':
break;
default:
$model->setState('filter.author_id', (int) $params->get('user_id'));
break;
}
// Filter by language
$model->setState('filter.language',$app->getLanguageFilter());
// Featured switch
switch ($params->get('show_featured'))
{
case '0':
$model->setState('filter.featured', 'hide');
break;
case '1':
default:
$model->setState('filter.featured', 'show');
break;
case '2':
$model->setState('filter.featured', 'only');
break;
}
// Set ordering
$order_map = array(
'0' => 'a.created',
'1' => 'a.hits',
'2' => 'a.ordering',
'3' => 'RAND()',
);
$ordering = "catid, ";
$ordering .= JArrayHelper::getValue($order_map, $params->get('order_by'), 'a.publish_up');
//$ordering = JArrayHelper::getValue($order_map, $params->get('order_by'), 'a.publish_up');
echo $ordering;
//help ordering system for DESC or ASC
switch ($params->get( 'order_type' ))
{
case 1:
$dir = 'DESC';
break;
case 0:
default:
$dir = 'ASC';
break;
}
$model->setState('list.ordering', $ordering);
$model->setState('list.direction', $dir);
//Filter and Set Period (days)
$model->setState('filter.date_filtering', 'relative');
$model->setState('filter.relative_date', $period);
$items = $model->getItems();
