自己在做酒店管理的时候,直接做成无限极,顺便将代码分享出来 //酒店和房型信息列表<br>
public function index(){<br>
$Hotel=M('Hotel');<br>
$hotelList=$Hotel->field('id,name,pid,path,concat(path,"-",id) as bpath ,sort')->order('sort desc,bpath')->select();<br>
foreach ($hotelList as $k=>$v){<br>
$hotelList[$k]['count']=intval(count(explode('-',$v['path']))-1); // 判断无限极层次深度<br>
}<br>
if($hotelList){<br>
$this->hotelList=$hotelList;<br>
}<br>
$this->display();<br>
}<br>
<br>
<br>
//添加酒店/房型<br>
public function add(){<br>
if(IS_POST){ //post方法提交<br>
if($_POST['name']==''){<br>
$this->success('名称不能为空!');die;<br>
}<br>
$Hotel=M('Hotel');<br>
if(intval($_POST['pid']) > 0){<br>
$parent=$Hotel->where(array('id'=>$this->_post('pid')))->find();<br>
$_POST['path']=$parent['path'].'-'.$_POST['pid'];<br>
}<br>
$_POST['time']=time();<br>
$data=getPost($_POST);//转义所有进入post方法的非法字符<br>
$Hotel=M('Hotel');<br>
if($Hotel->add($data)){<br>
$this->success('保存成功!');<br>
}else {<br>
$this->error('保存失败!');die;<br>
}<br>
}else{<br>
$this->error('非法请求');<br>
} <br>
}<br>
