首先看数据库表:xp_cate

控制器:CateAction.class.php
field("id,name,pid,path,concat(path,'-',id) as bpath")->order('bpath')->select();
foreach($list as $key=>$value){
$list[$key]['count']=count(explode('-',$value['bpath']));
}
$this->assign('alist',$list);
$this->display();
}//添加栏目
function add(){
$cate=new CateModel();if($vo=$cate->create()){
if($cate->add()){
$this->success('添加栏目成功');
}else{
$this->error('添加栏目失败');
}
}else{
$this->error($cate->getError());
}
}}
?>模型:CateModel.class.php
where("id=$pid")->find();
$data=$list['path'].'-'.$list['id'];//子类的path为父类的path加上父类的id
}
return $data;
}
}
?>模板:index.html
显示结果如下:
