thinkphp5.1 商品分类

商品分类实现无限级分类：

递归：
–controller

 public function index()
	    {
	
	        $CatModel = new CatModel();
	        $get_cats = $CatModel->getCats();
	
	        $cats = $this->getTree($get_cats);
	        $this->assign('cats',$cats);
	
	        return $this->fetch('list');
	    }
	
	    private function getTree($data,$pid=0,$level=0){
	
	        static $list = [];
	
	        foreach ($data as $k=>$v){
	
	            if ($v['pid']==$pid){
	                $v['level'] = $level;
	                $list[] = $v;
	                $this->getTree($data,$v['id'],$level+1);
	            }
	        }
	            return $list;
	    }

–model

public function getCats(){

        return $this->select();
    }

–view

{volist name="cats" id="vo"}
    <tr>
      <td>{$i}</td>
      <td>{$vo.level|str_repeat='--',###}{$vo.cat_name}</td>

      <td><div class="button-group"> <a class="button border-main" href="cateedit.html"><span class="icon-edit"></span> 修改</a> <a class="button border-red" href="javascript:void(0)" onclick="return del(1,2)"><span class="icon-trash-o"></span> 删除</a> </div></td>
    </tr>
    {/volist}
