Calculate Maximum Orders

apply_filters( 'vikrestaurants_calculate_max_orders_per_interval', int $max, int $default, array $times, object $slot, mixed $search )

Fires while fetching the maximum number of accepted orders per interval.

Description

Plugins can use this hook to change at runtime the maximum number of accepted orders per interval.

NOTE: it is possible to use $slot->ordersCount to retrieve the total number of orders that were placed for this time slot. Only the orders with the same service specified from the configuration will be counted. In case you decided to limit the orders only for delivery service, any pickup order won't be counted.

Parameters

$max

(int)  The new maximum value.

$default

(int)  The default maximum value.

$times

(array)  The current working shift and all the related timeslots.

$slot

(object)  The current timeslot/interval.

$search

(VREAvailabilityTakeaway)  The instance used to fetch the times availability.

Example

The example below doubles the maximum number of accepted orders for purchases made in the week-end.

/**
