Inheritance | yii\widgets\Block » yii\base\Widget » yii\base\Component » yii\base\Object |
---|---|
Implements | yii\base\Configurable, yii\base\ViewContextInterface |
Available since version | 2.0 |
Source Code | https://github.com/yiisoft/yii2/blob/master/framework/widgets/Block.php |
Block records all output between begin() and end() calls and stores it in yii\base\View::$blocks.
for later use.
yii\base\View component contains two methods yii\base\View::beginBlock() and yii\base\View::endBlock(). The general idea is that you're defining block default in a view or layout:
<?php $this->beginBlock('messages', true) ?> Nothing. <?php $this->endBlock() ?>
And then overriding default in sub-views:
<?php $this->beginBlock('username') ?> Umm... hello? <?php $this->endBlock() ?>
Second parameter defines if block content should be outputted which is desired when rendering its content but isn't desired when redefining it in subviews.
