我使用以下代码获取5个最活跃的用户ID。
public function actionAllstats()
{
$this->layout='main';
$user=UserJoinEvent::model()->findAll(array(//yeh hum model isi query mein chala raya hain because jab mein ne
//yeh $rbmodel=userjoinevent::model->findall() se kia tha to yeh mujhay saray results userjoinevent ke show raha
//tha, matlab sari user_id of this table show kar raha tha
'select'=>'user_id',
'group'=>'user_id',
'order'=>'COUNT(*) DESC',
'limit' => 5
));
$this->render('allstats', array("user"=>$user));
}
，视图文件为
<div>
<?php
foreach($user as $show)
{
echo '<h3>' . $show->user_id . '</h3>';
}
?>
</div>
如何才能获取用户名称，其名称来自用户模型。这是用户模型的代码
<?php
