cakephp find('list') for select box

问题

I am trying to implement selectbox in my site.Option for that selectbox is set in my controller like below

$tmp_user = $this->User->find('first',array('id'=>$this->Auth->user('id')));
                $zip_info = $this->Zipcode->find('first',array('id'=>@$tmp_user['User']['zip_id']));
                $region_admins = $this->AdminRegion->find('all',array('conditions'=>array('AdminRegion.region_id'=>@$zip_info['Zipcode']['region_id'])));

if(!empty($region_admins)){         
                    foreach($region_admins as $radmn):
                        //pr($radmn);
                        $admin_user = $this->User->find('list',array('conditions'=>array('id'=>$radmn['AdminRegion']['user_id']),'fields'=>array('id','username')));                
                        pr($admin_user);
                        $this->set('users',$admin_user);
                    endforeach;

I am getting value like this when i print from controller

    [137] => governmentuser1

    [198] => testadmin

)
Array

How about something like this:

<?php
    $tmp_user = $this->User->find('first', array(
                    'id' => $this->Auth->user('id')
                ));

    $zip_info = $this->Zipcode->find('first', array(
                    'id' => @$tmp_user['User']['zip_id']
                ));
    $region_admins = $this->AdminRegion->find('list', array(
                        'conditions' => array(
                            'AdminRegion.region_id' => @$zip_info['Zipcode']['region_id']
                        ),
                        'fields' => array('AdminRegion.user_id', 'AdminRegion.user_id')
                     ));

    $admin_users = $this->User->find('list', array(
                        'conditions' => array(
                            'id' => $region_admins
                        ),
                        'fields' => array(
                            'id','username'
                        )
                    ));

    ?>

A few side notes:

Why do another query for the user data? Isn't it all in the session?
I wouldn't use the @ anywhere, it's slower and suppresses errors. It will make debugging a nightmare too.

I think you missed array:

$admin_user[] = $this->User->find('list',array('conditions'=>array('id'=>$radmn['AdminRegion']['user_id']),'fields'=>array('id','username')));

Hope it helps
