添加函数

/*面包屑导航*/
function get_bread_nav($module,$trem_id){
     $arr['href']['action']=$module;
     $arr['href']['param']['id']=$trem_id;
     $nav=M('nav');
     $rs=$nav->select();
     foreach($rs as $k=>$v){
         $rs[$k]['href']=unserialize(stripslashes($v['href']));
     }

            if($v['href']==$arr['href']){
                $a=$v;
            }
         }
        $bread_path=$a['path'];
        $arr_path=explode("-",$bread_path);
        $str_path=" <li><a href='/' class='icon-home'> 首页</a></li>";
     
        for($i=1;$i<count($arr_path);$i++){
            $breadtitle=$nav->where("id=$arr_path[$i] and status=1 ")->find();
            $breadtitle['href']=unserialize($breadtitle['href']);
            $href=leuu($breadtitle['href']['action'],array('id'=>$breadtitle['href']['param']['id']));
            $str_path.="<li><a href=$href>".$breadtitle['label']."</a></li>";
        }

          $str_path="<li><a href='/' class='icon-home'> 首页</a></li>";
