yii2 添加城市功能save()问题
我想要添加该省份下的城市和改城市对应的级别(A,B,C,D,E),省份和级别都是字符串,但城市可能是一个或多个一个的话就是字符串,多个就是数组,如果为数组改怎么添加数据库(如果有两个城市就要添加两条记录,如 江苏省,苏州市,B ; 江苏省,南京市,B),并且所有数据插入成功要返回1,有一条失败就返回0,求解决
<code>public function add($post){ $province = $post['province']; $citys = $post['city']; $city_level = $post['city_level']; var_dump($citys);exit; $this->province = $province; $this->city_level = $city_level; foreach ($citys as $city){ $this->city = $city; if($this->save()){ return 1; }else{ return 0; } } }</code>

数据库其实设计的不好:
id | parent_id | name |
---|---|---|
1 | 0 | 北京 |
2 | 1 | 海淀 |
3 | 1 | 朝阳 |
用一个 parent_id
来控制层级关系即可
