In this section, we create the last portlet that displays a list of comments recently published.
RecentComments
Class ¶We create the RecentComments
class in the file /wwwroot/blog/protected/components/RecentComments.php
. The file has the following content:
Yii::import('zii.widgets.CPortlet');
class RecentComments extends CPortlet
{
public $title='Recent Comments';
public $maxComments=10;
public function getRecentComments()
{
return Comment::model()->findRecentComments($this->maxComments);
}
protected function renderContent()
{
$this->render('recentComments');
}
}
In the above we invoke the findRecentComments
method which is defined in the Comment
class as follows,
class Comment extends CActiveRecord
{
......
public function findRecentComments($limit=10)
{
return $this->with('post')->findAll(array(
'condition'=>'t.status='.self::STATUS_APPROVED,
'order'=>'t.create_time DESC',
'limit'=>$limit,
));
}
}
recentComments
View ¶The recentComments
view is saved in the file /wwwroot/blog/protected/components/views/recentComments.php
. It simply displays every comment returned by the RecentComments::getRecentComments()
method.
RecentComments
Portlet ¶We modify the layout file /wwwroot/blog/protected/views/layouts/column2.php
to embed this last portlet,
...... <div id="sidebar"> if(!Yii::app()->user->isGuest) $this->widget('UserMenu'); $this->widget('TagCloud', array( 'maxTags'=>Yii::app()->params['tagCloudCount'], )); $this->widget('RecentComments', array( 'maxComments'=>Yii::app()->params['recentCommentCount'], )); </div> ......
