yii\widgets\ContentDecorator - Yii2 类参考手册

Class yii\widgets\ContentDecorator

Inheritanceyii\widgets\ContentDecorator » yii\base\Widget » yii\base\Component » yii\base\BaseObject
Implementsyii\base\Configurable, yii\base\ViewContextInterface
Available since version2.0

ContentDecorator records all output between begin() and end() calls, passes it to the given view file as $content and then echoes rendering result.

<?php ContentDecorator::begin([
    'viewFile' => '@app/views/layouts/base.php',
    'params' => [],
    'view' => $this,
]) ?>

some content here

<?php ContentDecorator::end() ?>

There are yii\base\View::beginContent() and yii\base\View::endContent() wrapper methods in the yii\base\View component to make syntax more friendly. In the view these could be used as follows:

<?php $this->beginContent('@app/views/layouts/base.php') ?>

some content here

<?php $this->endContent() ?>
