此节中,我们创建最后一个 portlet ,它将显示最新发布的评论列表。
RecentComments
类 ¶我们将 RecentComments
类创建在文件 /wwwroot/blog/protected/components/RecentComments.php
中。此文件内容如下:
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()
{
$this->render('recentComments');
}
}
如上所示,我们调用了 Comment
类中定义的 findRecentComments
方法。此方法代码如下:
class Comment extends CActiveRecord
{
......
public function findRecentComments($limit=10)
{
return $this->with('post')->findAll(array(
'condition'=>'t.status='.self::STATUS_APPROVED,
'order'=>'t.create_time DESC',
'limit'=>$limit,
));
}
}
recentComments
视图 ¶recentComments
视图存储在文件 /wwwroot/blog/protected/components/views/recentComments.php
中。它只是简单的显示由 RecentComments::getRecentComments()
方法返回的每一条评论。
RecentComments
Portlet ¶我们修改布局文件 /wwwroot/blog/protected/views/layouts/column2.php
插入最后这个 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> ......
