{loop subcat(0,0,0,$siteid) $r}{/loop}
获取子栏目：
@param $parentid 父级id @param $type 栏目类型 @param $self 是否包含本身 0为不包含 @param $siteid 站点id
在PHPCMS中的函数定义代码如下：
function subcat($parentid = NULL, $type = NULL,$self = '0', $siteid = '') {
if (empty($siteid)) $siteid = get_siteid();
$category = getcache('category_content_'.$siteid,'commons');
foreach($category as $id=>$cat) {
if($cat['siteid'] == $siteid && ($parentid === NULL || $cat['parentid'] == $parentid) && ($type === NULL || $cat['type'] == $type)) $subcat[$id] = $cat;
if($self == 1 && $cat['catid'] == $parentid && !$cat['child']) $subcat[$id] = $cat;
}
return $subcat;
}
