Laravel table joins - php

Question

I'm trying to do some table joins and having some trouble.i need to display
the customer’s complete name and title, item description, quantity ordered, for each item ordered after April 2000. i made a SQL script that works but i need to use Laravel ORM.
SELECT `first_name`,`last_name`,o.order_id,`quantity`,`description`,`date_placed`
FROM `customer` c
JOIN `order` o
ON c.`customer_id` = o. `customer_id`
JOIN `orderline` ol
ON o.`order_id` = ol. `order_id`
JOIN `item` i
ON ol.`item_id` = i. `item_id`
WHERE `date_placed` > '2000-4-00';
I created 2 models for the tables "Customer", "Order"
here is my Customer model
public function orders(){
return $this->hasMany('App\Order','customer_id');
}
here is my order model
public function orderline(){
return $this->hasMany('App\Orderline','order_id');
}
right now i am able to get some of my data but i dont feel like this is a good way to go about
$customer = Customer::all();
foreach($customer as $input){
$item = Customer::find($input->customer_id)->orders;
$name = $input->title . ' ' . $input->first_name . ' ' . $input->last_name;
$datePlaced = null;
$orderID = null;
foreach($item as $value){
$orderID = $value->order_id;
$datePlaced = $value->date_placed;
$order = Order::find($value->order_id)->orderline;
}
if anyone could point me in the right direction that would be great.

It looks like you want to get all Customers with their Orders and OrderLines?
Customer::with(['order' => function ($query) {
$query->where('date_placed', '>=', '2000-04-01')->with('orderline');
}])->get();
If you want to limit the columns on the relationships, you can...
Customer::with(['order' => function ($query) {
$query->select(/* columns */)->where('date_placed', '>=', '2000-04-01')
->with(['orderline' => function ($query) {
$query->select(/* columns here */);
}]);
}])->get();
Just make sure if you specify the columns in the relationships, that you're selecting all of the foreign keys or related columns for each relationship.
