How to get an entity and a count in the same query? - php

Question

I've created the following repository and method. The method does what you would expect it to do except for one thing. It cannot return both ->select('ol') and ->select('count(ol.product) as totalProducts'). As soon as I inclode the ->select('ol') it will ignore the count.
class OrderLineRepository
{
// ...
public function getOpenOrders()
{
$qb = $this->createQueryBuilder('ol');
$orders = $qb
->select('count(ol.product) as totalProducts')
->select('ol')
->where('BIT_AND(ol.flags, 3) = 2')
->groupBy('ol.orderId')
->setMaxResults(100)
->getQuery()
->getResult()
;
return $orders;
}
// ...
}
I am still in the early stages of mastering symfony and this could possibly quite a stupid question. But it's still a question I'm currently facing. Can someone help me out?
Update
Witht the help of RiggsFolly I now get the following result by using ->addSelect(...) instead of ->select(...).
array:10 [
// ...
array:2 [
0 => OrderLine {
id: 8068005
product: Product {#1503 ▶}
supplier: Supplier {#1552 ▶}
reference: Reference {#1528 ▶}
}
"products" => "3"
]
// ...
]
Ideally, I would like to get it like this:
array:10 [
// ...
array:2 [
id: 8068005
product: Product {#1503 ▶}
supplier: Supplier {#1552 ▶}
reference: Reference {#1528 ▶}
"products" => "3"
]
// ...
]

I don't know how it's related OrderLine and Products if it is; but maybe you can create a DB relation between it, so you would get an array of products related to your OrderLine.
Finally, to get the number of products:
$productsNumber = count($orderLine->getProducts());
UPDATE
In this case, total Products will be the same as total OrderLines, is that correct?
So... total products is not an OrderLine attribute, in my opinion; and it should not be part of your OrderLine object, instead, you probably can count the OrderLines objects retrieved by Doctrine, and it will be your totalProduct.
Looking a little further, you can also create an Order entity, that is related to your OrderLine object (One to Many). Then, you could query for your Order entity using Doctrine, and count the OrderLines attribute of your Order entity, which will be the same as the total products.
