YII数据库删除记录示例 _删除记录

若要删除数据库中的记录, 请按照下列步骤操作。我们已将Yii2文件夹命名为delete。
步骤1创建模型文件
在frontend / models文件夹中创建一个模型文件child.php。

< ?php namespace app\models; use Yii; class Child extends \yii\db\ActiveRecord { /** * @inheritdoc */ public static function tableName() { return 'child'; } /** * @inheritdoc */ public function rules() { return [ [['name', 'meaning', 'gender'], 'required'], [['name', 'meaning'], 'string', 'max' => 100], [['gender'], 'string', 'max' => 15] ]; } }

【YII数据库删除记录示例】步骤2在控制器中创建动作
在ChildController.php文件中创建一个actionDelete动作。

< ?php namespace frontend\controllers; use Yii; use app\models\Child; use yii\web\Controller; /** * manual CRUD **/ class ChildController extends Controller {/** * Create */ public function actionCreate() { $model = new Child(); // new record if($model-> load(Yii::$app-> request-> post()) & & $model-> save()){ return $this-> redirect(['index']); } return $this-> render('create', ['model' => $model]); } /** * Read */ public function actionIndex() { $child = Child::find()-> all(); return $this-> render('index', ['model' => $child]); } /** * Edit * @param integer $id */ public function actionEdit($id) { $model = Child::find()-> where(['id' => $id])-> one(); // $id not found in database if($model === null) throw new NotFoundHttpException('The requested page does not exist.'); // update record if($model-> load(Yii::$app-> request-> post()) & & $model-> save()){ return $this-> redirect(['index']); } return $this-> render('edit', ['model' => $model]); } /** * Delete * @param integer $id */ public function actionDelete($id) { $model = Child::findOne($id); // $id not found in database if($model === null) throw new NotFoundHttpException('The requested page does not exist.'); // delete record $model-> delete(); return $this-> redirect(['index']); }}

步骤3运行
在浏览器上运行它。
