Accessing the Order object from the Cart Id in Prestashop

I am POSTing the Cart id to my module method. From that I can obviously create the Cart object using that id. But how do I access the Order object that corresponds to that Cart object?

I've tried something like;

$cart = new Cart($_POST['id']);

var_dump($this->context->order);

And also trying to do a sort of where() query on the Order (where id_cart is equal to the id in my Cart object);

$order = new Order('id_cart', $cart->id);

It is probably really obvious but I just don't know Prestashop very well.

The reason I am trying to do this is so I change the status of an Order if the payment has timed out.

I win;

$order = Order::getOrderByCartId((int)($cart->id));

Try

$order = Order::getByCartId($cart->id)

I am passing ```$cart->id``` to function in my module and then I pass it to .tpl where I can access it.

But in function in controller I can not get to an order object

Either:
```php
$order = Order::getByCartId($cart->id)
```
or
```php
$order = Order::getOrderByCartId((int)($cart->id));
```
no results.
I have

```php
public function displayMyHooKName($params) {

$id_cart = $params['id_cart'];
/* $id_cart has value of cart id - I have checked */


}
```

I tried:
```php
$cart = new Cart($params['id_cart']);

$order = Order::getOrderByCartId((int)($cart->id));
/*or*/
$order = Order::getByCartId($cart->id);


```

so how to access ```php$order``` knowing ```$cart->id``` ?

*******
OK
```php
$order = Order::getOrderByCartId((int)($cart->id));
```
gives back
```php
#order_id
```

so I did:
```php

$cart = new Cart($params['id_cart']);
$orderID = Order::getOrderByCartId((int)($cart->id));
$order = new Order($orderID);

$products = $order->getProducts();
```

and my
```php
$products
```
is empty

*******
SOLVED

OK I got it. Code above is 100% correct and it works as it should.

I was smart enough to try to get data from order object - before order was placed:) Was calling my hook on order-address.tpl.

So products data were in
```php
$cart->getProducts();
```

However maybe my case will help someone.
