Sometimes, views share the same common portion of content. In the examples made until now, we have seen that a common area for itemsList and itemDetail could be copyright data, which displays a disclaimer about copyright info.
In order to make this, we must put the common content in a separate view and call it using the renderPartial() method of controller (http://www.yiiframework.com/doc-2.0/yii-base-controller.html#renderPartial%28%29-detail). It has the same types of parameters of the render() method; the main difference between the render() and renderPartial() methods is that render() writes a view content in layout and renderPartial() writes only view contents to output.
In this example, we create a common view for both itemsList and itemDetail about copyright data.
Create a view file named _copyright.php in views/news.
In this file, put only a text for copyright into views/news/_copyright.php:
<div>
This is text about copyright data for news items
</div>Now, we want to display this view inside the itemsList and itemDetail views.
Change the content in itemsList.php located at views/news/ as follows:
<?php echo $this->context->renderPartial('_copyright'); ?>
<table>
<tr>
<th>Title</th>
<th>Date</th>
</tr>
<?php foreach($newsList as $item) { ?>
<tr>
<th><a href="<?php echo Yii::$app->urlManager->createUrl(['news/item-detail' , 'id' => $item['id']]) ?>"> <?php echo $item['title'] ?> </a></th>
<th><?php echo Yii::$app->formatter->asDatetime($item['date'], 'php:d/m/Y'); ?></th>
</tr>
<?php } ?>
</table>Then, change the content in itemDetail.php located at views/news/ as follows:
<?php // $item is from actionItemDetail ?>
<?php echo $this->context->renderPartial('_copyright'); ?>
<h2>News Item Detail<h2>
<br />
Title: <b><?php echo $item['title'] ?></b>
<br />
Date: <b><?php echo $item['date'] ?></b>We have put a common code at the top of the file in both views:
<?php echo $this->context->renderPartial('_copyright'); ?>This will render the content of the _copyright.php view without layout.
