thinkphp5实现无限级分类(2)

public function edit(Request $request)
{
 //1.获取一下分类id
 $cate_id = $request -> param('id');
 
 //2.查询要更新的数据
 $cate_now = CategoryModel::get($cate_id);
 
 //3.递归查询所有的分类信息
 $cate_level = CategoryModel::getCate();
 
 //4.模板赋值
 $this -> view -> assign('cate_now', $cate_now);
 $this -> view -> assign('cate_level', $cate_level);
 
 
 //5.渲染模板
 return $this -> view -> fetch('category_edit');
}
