subcat获取指定数目的分类

1. {php $k=0}
   
2. {loop subcat($catid,0,0,$siteid) $v}
   
3. {loop subcat($v[catid],0,0,$siteid) $r}
   
4. {php $k++}
   
5. <li><a href="{$r[url]}"><img src="{$r[image]}"></a></li>
   
6. {/loop}
   
7. {php if($k>6) break;}
   
8. {/loop}

复制代码

{php if($k>6) break;}

这句话限制了  如果 $k大于6  就终止循环

此函数在global.func.php中定义
function subcat($module = 'phpcms', $parentid = NULL, $type = NULL)
{
        global $CATEGORY;
        $subcat = array();
        foreach($CATEGORY as $id=>$cat)
        {
                if($cat['module'] == $module && ($parentid === NULL || $cat['parentid'] == $parentid) && ($type === NULL || $cat['type'] == $type)) $subcat[$id] = $cat;
        }
        return $subcat;
}
