php - 根据用户的 id 获取用户的名称

Question

我使用以下代码来获取 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));
            } 

View 文件是

<div>
        <?php
            foreach($user as $show)
            {
                echo '<h3>' . $show->user_id . '</h3>';
            }
        ?>
    </div>

我如何根据用户的 ID 获取用户的名称，该名称来自用户模型。这是用户模型的代码

<?php

这是用户加入事件模型

谢谢。

Answer 1

    This is a simple solution, not a good pratice but really simple 
    You decode the value you need inside the show loop.. For a fast solution can be useful 

And a allstat.php(in the view file of UserJoinEvent) which is

<div>
    <?php
        foreach($user as $show)
        {
           $model = User::model()->findByAttributes(array('id'=>$show->user_id,));
           if (isset($model)) then {
               echo '<h3>' . $show->user_id .  ' - ' . $model->username . '</h3>';
           } else {
               echo '<h3>' . $show->user_id .  ' - Username not found</h3>';
           }

        ?>
    </div>
