phpcms 这样条件的栏目怎样调用呢

条件是:parentid  等于1的所有栏目,我想调出来,不知如何写啊

我这样写:
{pc:content action="category" parentid="1" num="25" siteid="$siteid" order="listorder ASC"}
          {loop $data $r}
          

{$r[catname]}

          {/loop}
          {/pc}
调不出来呢

回复讨论(解决方案)

	/**	 * 栏目标签	 * @param $data	 */	public function category($data) {		$data['catid'] = intval($data['catid']);		$array = array();		$siteid = $data['siteid'] && intval($data['siteid']) ? intval($data['siteid']) : get_siteid();		$categorys = getcache('category_content_'.$siteid,'commons');		$site = siteinfo($siteid);		$i = 1;		foreach ($categorys as $catid=>$cat) {			if($i>$data['limit']) break;			if((!$cat['ismenu']) || $siteid && $cat['siteid']!=$siteid) continue;			if (strpos($cat['url'], '://') === false) {				$cat['url'] = substr($site['domain'],0,-1).$cat['url'];			}			if($cat['parentid']==$data['catid']) {				$array[$catid] = $cat;				$i++;			}		}		return $array;	}	

从该标签实现看，没有parentid参数
