{pc:content action="lists" catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
{loop $info $v}

target="_blank" title="{$v["title']}"{title_style($v)}>{str_cut($v['title'],28)}
{str_cut($v['description'],100)}

{/loop}
{/pc}

{pc:content action="lists" catid="$r" num="5" order="id DESC" return="info"}

{loop $info $v}

• ·{str_cut($v['title'],40)}

{/loop}

{/pc}

{if $num%2==0}{/if}
{/if}

=====================================================

{loop subcat(0,0,0,$siteid) $r}{/loop}函数解释：

{loop subcat(0,0,0,$siteid) $r}{/loop}

/**

* 获取子栏目
* @param $parentid 父级id
* @param $type 栏目类型 1为单网页类型，0为栏目类型；（查看phpcms的mysql数据库可以看到）
* @param $self 是否包含本身 0为不包含
* @param $siteid 站点id
*/
function subcat($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;
