实现无限极栏目分类思路: 获取自增加ID(也就是父ID) 然后在到数据库获取子ID(也就是uid子id) 数据如下
id:1  uid:0  我是栏目1
id:2  uid:1  我是栏目2
id:3  uid:1  我是栏目1的子类

显示结果:                                                
我是栏目1                                                
我是栏目1的子类
我是栏目2               

下面是Php代码

复制代码 代码如下:

 $query = $this->db->query("SELECT * FROM category");
 $list = $query->result();
 foreach($list as $v){
 if($v->category_id == 0){//获取父栏目(等于0的都是父栏目)
 $categoryul = anchor("home/content/".$v->id,$v->category_name);
 echo "
    ".$categoryul."
";
 $listx = $this->Listx->list_id($v->id);//在根据父id显示出指定的子栏目
 foreach($listx as $vid){

 $category = anchor("home/content/".$vid->id,$vid ->category_name);
 echo "
  • ".$category."
  • ";
       }
        }
      }
    ?>
