Array element returning null in laravel-4 - php

Question

I'm trying to get records from a table using a given ID and I want to store specific columns into another array but I'm getting null every time I var_dump() my array.
My code:
$getOrder = array();
foreach($ordersInWaypoint as $ordersInWaypoints)
{
$getOrder[] = array(
array($ordersInWaypoints),
array(Order::where('id', '=', $ordersInWaypoints)->get()->lists('tracking_id')),
array(Order::where('id', '=', $ordersInWaypoints)->get()->lists('shipper_ref_no'))
);
}
For those wondering where $ordersInWaypoint came from, I retrieved that from here:
$ordersInWaypoint = array();
ordersInWaypoint = Transaction::where('waypoint_id', "=", $firstWaypoint)->get()->lists('order_id');
Don't mind the $firstWaypoint since that is determined by user input.
Everytime I var_dump($getOrder); I get the following result set:
array (size=1)
0 =>
array (size=3)
0 =>
array (size=1)
0 => int 637
1 =>
array (size=1)
0 =>
array (size=1)
...
2 =>
array (size=1)
0 =>
array (size=1)
...
The first element is correct, but the rest return empty sets.

I think you're getting no value because those Order::where(...) return Eloquent objects, not just single values.
You could better try this way:
$getOrder = array();
foreach($ordersInWaypoint as $ordersInWaypoints)
{
$order = Order::where('id', '=', $ordersInWaypoints)->get();
$getOrder[] = array(
array($ordersInWaypoints),
array($order->tracking_id),
array($order->shipper_ref_no)
);
}
Let me know if this fixes it ;)
Edit
It's even better if you don't use a multidimensional array as you need just these three values, so the final code becomes:
$getOrder = array();
foreach($ordersInWaypoint as $ordersInWaypoints)
{
$order = Order::where('id', '=', $ordersInWaypoints)->get(); // create Eloquent object from query
$getOrder[] = array(
$ordersInWaypoints,
$order->tracking_id, // Calls column value as method from the Eloquent object
$order->shipper_ref_no // Same (you could also call it as an array,
); // in that case you would type $order['shipper_ref_no']
}
