[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();?>
