Display rows returned by query - yii2

Question

I am a total beginner in yii2. I have an actionView in my controller to which I pass the $id. I have written a query which returns the join from 3 tables. I want to know how can I display specific columns from these rows in my view named view. This is my actionView...
public function actionView($id)
{
$select = [
'user.username',
'package_subscriptions.package_id',
'order.order_number',
];
$query = new Query;
$query->select($select)
->from('order')
->innerJoin(['user'],'order.user_id = user.id')
->innerJoin(['package_subscriptions'],'order.user_id = package_subscriptions.user_id')
->all();
return $this->render('view', [
// What should I write here
]);
}

Answer 1

import Query class
use yii\db\Query;
Code in your actionView
public function actionView($id)
{
$select = [
'user.username as username',
'package_subscriptions.package_id as package_id',
'order.order_number as order_number',
];
$query = new Query;
$query->select($select)
->from('order')
->innerJoin(['user'],'order.user_id = user.id')
->innerJoin(['package_subscriptions'],'order.user_id = package_subscriptions.user_id');
$command = $query->createCommand();
$list = $command->queryAll();
return $this->render('view', [
'data'=>$list, // pass data to view
]);
}
Query return an array ,you can use in view as below :
foreach($data as $val)
{
echo $val['username'];
echo $val['package_id'];
echo $val['order_number'];
}

Answer 2

try this
public function actionView($id)
{
$select = [
'user.username',
'package_subscriptions.package_id',
'order.order_number',
];
$query = new Query;
$results= $query->select($select)
->from('order')
->innerJoin(['user'],'order.user_id = user.id')
->innerJoin(['package_subscriptions'],'order.user_id = package_subscriptions.user_id')
->all();
return $this->render('view', [
'results'=>$results
]);
}
in your view.php
<?
foreach($results as $result){
?>
username:<?=$result['username']?>
<br>
Package id:<?=$result['package_id']?>
<br>
order number:<?=$result['order_number']?>
<?
}
?>
