Yii2 HOW-TO：把数据从控制器传递到视图

Posted 2021-01-06

控制器类中定义数据

public function actionIndex()
{
        $h1 = ‘这是一个主标题!‘;
        $h4 = ‘这是一个副标题‘;
        $dateTime = new DateTime();

        return $this->render(‘index‘, [‘title‘ => $h1, ‘subTitle‘ => $h4,‘dateTime‘=>$dateTime]);
}

视图中使用数据

<?php
use yiihelpershtml;

$this->title = ‘Login‘;
?>
<div class="site-index">

    <div  class="jumbotron">
        <h1><?= Html::encode($this->title); ?></h1>
    </div>

    <div style="text-align: center;">
        <?= $subTitle ?>
    </div>
    <div style="text-align: right;">
        <?= $dateTime->format(‘Y-m-d H:i:s‘);  ?>
    </div>
</div>
