Php无限级栏目分类读取的实现代码
下面给大家分享一个Php实现无限栏目分类读取的例子,希望文章对各位会带来帮助
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 "
}
}
}
?>
