Check Reservation

apply_filters( 'vikrestaurants_check_reservation_cancellation', bool $allow, object $reservation )

Fires while checking whether the cancellation is allowed for the specified reservation.

Description

This filter can be used to apply additional conditions to the cancellation restrictions. Applies only for restaurant reservations.

When this hook is triggered, the system already validated the standard conditions and the cancellation has been approved for the usage.

In case of allowed cancellation, the page containing the reservation details will report a button to cancel the reservation.

Parameters

$allow

(bool)  Use false to deny the cancellation.

$reservation

(VREOrderRestaurant)  An object containing the details of the reservation that is going to be cancelled.

Example

The example below prevents the cancellation for those customers that never booked a table. In summary, the cancellation will be allowed starting from the second table booking.

/**

 *
 * @param  boolean  $allow        Use false to deny the cancellation.
 * @param  mixed    $reservation  The restaurant reservation to check.
