[moka同学笔记]yii2.0小物件的简单使用（第二种方法）

1.在widgets/TestWidget.php中

 <?php
 /**
  * Created by PhpStorm.
  * User: moka同学
  * Date: 2016/08/05
  * Time: 18:15
  */
 namespace app\widgets;

 use yii\base\Widget;

 class TestWidget extends Widget
 {
     public $msg = '';

     //初始化
     public function init()
     {
         parent::init(); // TODO: Change the autogenerated stub
     }

     //覆盖
     public function run()
     {
         return $this->render('index',['msg'=>$this->msg]);
     }
 }

2.在widgets/views/index.php

 <?php
 /**
  * Created by PhpStorm.
  * User:moka同学
  * Date: 2016/08/05
  * Time: 18:20
  */
 echo $msg.'这个是公共部分';
 ?>

3.在其他需要使用的视图文件中 如下调用即可

<?php
/**
 * Created by PhpStorm.
 * User: moka同学
 * Date: 2016/08/05
 * Time: 16:15
 */
use app\widgets\TestWidget;
?>
<?= TestWidget::widget();?>
