Laravel WHERE scope on JOIN - php

Question

I am trying to get "shifts" and get all records I have,
But I join it with orders and run where on orders by delivery_date here "the shift" which has no orders erased
now I need to make the where only on orders and not affect on shifts
Shift::leftJoin('mt_plans', 'mt_plans.shift_id', '=', 'shifts.id')
->leftJoin('subscriptions', 'subscriptions.plan_id', '=', 'mt_plans.plan_id')
->join('orders', 'orders.subscription_id', '=', 'subscriptions.id')
->join('mt_order_details', 'mt_order_details.order_id', '=', 'orders.id')
->join('mt_item', 'mt_item.item_id', '=', 'mt_order_details.item_id')
->where('orders.delivery_date', $request->date)
->whereIn('orders.status', [OrderStatus::ACCEPTED, OrderStatus::ASSIGNED, OrderStatus::FAILED, OrderStatus::SUCCESSFUL])
->select([
'mt_item.item_id as meal_id',
'mt_item.en_name',
'mt_item.color',
'mt_item.label_number',
'shifts.id as shift_id',
'shifts.title',
'shifts.start_time',
'shifts.end_time',
'shifts.pickup_time'
])
->get();

You need a left join where your condition applies:
Shift::leftJoin('mt_plans', 'mt_plans.shift_id', '=', 'shifts.id')
->leftJoin('subscriptions', 'subscriptions.plan_id', '=', 'mt_plans.plan_id')
->leftJoin('orders', function($q) use($request) {
$q->on('orders.subscription_id', '=', 'subscriptions.id');
$q->where('orders.delivery_date', '=', $request->date);
})
->leftJoin('mt_order_details', 'mt_order_details.order_id', '=', 'orders.id')
->leftJoin('mt_item', 'mt_item.item_id', '=', 'mt_order_details.item_id')
->whereIn('orders.status', [OrderStatus::ACCEPTED, OrderStatus::ASSIGNED, OrderStatus::FAILED, OrderStatus::SUCCESSFUL])
->select([
'mt_item.item_id as meal_id',
'mt_item.en_name',
'mt_item.color',
'mt_item.label_number',
'shifts.id as shift_id',
'shifts.title',
'shifts.start_time',
'shifts.end_time',
'shifts.pickup_time'
])
->get();
Then you keep all "shifts" but join only order with delivery_date condition.
Keep in mind that it will retrieve all "shifts" where where condition applies. The orders will be null if doesn't match the id and delivery_date
