1. 调用模型

   $cate = new CateModel();
   $res = $cate->catetree();

2. 模型实现递归

      public function catetree()
       {
           $cateres = $this->select();
           return $this->sort($cateres);
       }
   
       public function sort($data,$pid=0,$level=0)
       {
           static $arr = array();
           foreach ($data as $key => $v) {
               if($v['pid'] == $pid){
                   $v['level'] = $level;
                   $arr[] = $v;
                   $this->sort($data,$v['id'],$level+1);
               }
           }
           return $arr;
       }

   3.视图输出

   <!--  表格显示 -->
   {volist name = "res" id = "vo"}
   <tr>
       <td align="center">{$vo.id}</td>
       <td align="left"><?php echo str_repeat('--------|',$vo['level'])?>{$vo.catename}</td>
       <td align="center">
           <!-- /以数组的方式传送参数id，用$vo['参数']这种方式/ -->
   
           <a href="{:url('edit',array('id'=>$vo['id']))}" class="btn btn-primary btn-sm shiny">
           <span class="glyphicon glyphicon-edit"></span>&nbsp;编辑
           </a>
           <a href="{:url('del',array('id'=>$vo['id']))}" onClick="window.confirm('确实要删除吗','index.html')" class="btn btn-danger btn-sm shiny">
           <span class="glyphicon glyphicon-trash"></span>&nbsp;删除
           </a>
       </td>
   </tr>
   {/volist}
