Sending mail in yii2?

Question

Yii

Good afternoon . I'm making a store in yii2. Can't send data from input button to email via swiftmailer. The mail itself is working fine. But I want to insert from input into a letter in a certain place, I can’t help pliz.
button - <?= $form->field($order, 'email') ?>
$email = Yii::$app->request->post('order[email]');
$email = post('order[email]'); - not suitable
Here are the main texts:
CartController.php :

public function actionView(){
$session = Yii::$app->session;
$session->open();
$this->setMeta('Корзина');
$order = new Order();
if( $order->load(Yii::$app->request->post()) ){
$order->qty = $session['cart.qty'];
$order->sum = $session['cart.sum'];

if($order->save()){
$this->saveOrderItems($session['cart'], $order->id);
Yii::$app->session->setFlash('success', 'Ваш заказ принят. Менеджер вскоре свяжется с Вами.');
Yii::$app->mailer->compose('order', ['session' => $session])
->setFrom(['[email protected]'])
->setTo($order->email)
->setSubject('Заказ')
->setTextBody('Текст сообщения')
->send();
$email = $oder->email;echo"$email";
Yii::$app->mailer->compose('order', ['session' => $session])
->setFrom(['[email protected]'])
->setTo('[email protected]')
->setSubject('Заказ')
->send();


$session->remove('cart');
$session->remove('cart.qty');
$session->remove('cart.sum');
return $this->refresh();
}else{
Yii::$app->session->setFlash('error', 'Ошибка оформления заказа');
}
}
return $this->render('view', compact('session', 'order',['order' => $order]));
}

in the folder mail - order.php:

<?php
use yii\helpers\Html;

That is, the code for transferring data from the input button to the letter.

He decided everything himself. Saving the drowning, as they say. Special thanks to Maxim Timofeev, he at least sent him in the right direction.
Here is the corrected code for anyone who may need it:
Cart.php
public function actionView(){
$session = Yii::$app->session;
$session->open();
$this->setMeta('Cart');
$order = new Order();
if( $order->load(Yii::$app->request->post()) ){
$order->qty = $session['cart.qty'];
$order->sum = $session['cart.sum'];
if($order->save()){
$email = [$order->email];
$name = [$order->name];
$phone = [$order->phone];
$address = [$order->address];
$this->saveOrderItems($session['
Yii::$app->session->setFlash('success', 'Your order has been accepted. The manager will contact you shortly.');
->setFrom(['[email protected]'])
->setTo($order->email)
->setSubject('Order')
->send();
->setFrom(['[email protected]'])
->setTo('[email protected]'
) ->setSubject('Order')
->send();
$session->remove('cart');
$session->remove('cart.qty');
$session->remove('cart.sum');
return $this->refresh();
}else{
Yii::$app->session->setFlash('error', 'Order checkout error');
}
}
return $this->render('view',compact('session', 'order'));
}
Order.php:
<?php
use yii\helpers\Html;
?>
Product details

Name	Qty	Price	Sum
<?= $item['name']?>	<?= $item['qty']?>	<?= $item['price']?>	<?= $item['qty'] * $item['price']?>
Total:	<?= $session['cart.qty']?>
For the amount:	<?= $session['cart.sum']?>

<?php $i = 1; foreach($name as $name): ?>
<?= "Name" ?>
<?= $name ?>
<?php $i++; endforeach; ?>
<?php $i = 1; foreach($email as $email): ?>
<?= "Email" ?>
<?= $email ?>
<?php $i++; endforeach; ?>
<?php $i = 1; foreach($phone as $phone): ?>
<?= "Phone" ?>
<?= $phone ?>
<?php $i++; endforeach; ?>
<?php $i = 1; foreach($address as $address): ?> <?= "Address" ?>
<?= $address ?>
<?php $i++; endforeach; ?>
