subcat

subcat函数的定义是在phpcms/libs/functions/global.func.php文件中

{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

函数原型如下：

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;
}

 

想到某个(如n)id终止循环则：

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

{php $num++}

{php if($r['catid']==n)break; }

...

{/loop}

想到某个(如a,b,c)id跳出循环，即：隐藏指定分类id栏目则：

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

{php $num++}

{php if($r['catid']==a || $r['catid']==b || $r['catid']==c)continue; }

...

{/loop}
