Yii2 Lesson

在SiteController.php中設置方法

    public function actionThree()
    {   
        $model = new Three();
        if($model->load(Yii::$app->request->post()) && $model->validate()) {
            Yii::$app->session->setFlash('success','Do it easy,Lesson 3');
        }   
        return $this->render('three',['model'=>$model]); 
    } 

新建一個模型類 Three.php

<?php
namespace appmodels;
use yiiaseModel;

class Three extends Model{
    public $name;
    public $email;

  public function rules()
  {
    return [
              [['name','email'],'required'],
              ['email','email'],
           ];
  }
}

定一个视图文件 views/site/three.php

<?php
use yiihelpersHtml;
use yiiwidgetsActiveForm;
?>
<?php
        if(Yii::$app->session->hasFlash('success')){
            echo Yii::$app->session->getFlash('success');
        }

?>
<?php  $form = ActiveForm::begin();?>
<?= $form->field($model,'name');?>
<?= $form->field($model,'email');?>
<?= Html::submitButton('submit',['class'=>'btn btn-success']);?>
~                                                                   

注意 commit 没反应的情况和 model中的rule格式有关系浪费我半小时
