第一步:sql注意:id要自增,怎么做才能自增呢?
models:记住,继承了ActiveRecord后,就得到了它所有的功能哦(注意,sql表要跟models相对应!!!)
<?php
namespace frontend\models;
use yii\db\ActiveRecord;
class Article extends ActiveRecord
{
}
控制器:注意,一个一个的来哦
<?php
namespace frontend\controllers;
use frontend\models\Article;
class IndexController extends \yii\web\Controller
{
public function actionIndex(){
//增加/*$article=new Article();$article->title="cyg";$article->created_at=time();$article->save();*///修改/*$article=Article::findOne(['id'=>1]);$article->title="lwien";$article->save();*///删除$article=Article::findOne(['id'=>1]);$article->delete();}}
