↑ Back to topMake calendar default to first available booking
↑ Back to topBy default the current month will be shown on the Bookings calendar for performance reasons. This will default it to the month with the first available block:
Modify the date in a booking’s summary
↑ Back to topA booking’s date in its summary is able to be modified with the wc_bookings_summary_list_date
filter. This filter passes three arguments, the original date string, the timestamp for the start, and the timestamp for the end.
This example will modify the date so that only the start date is returned for the summary:
Modify when In Cart bookings expire
↑ Back to topWhen bookings are added to the cart, they are immediately created. This allows for blocks to be properly reserved on the calendar. By default, these bookings expire after 60 minutes and are deleted by a WP Cron event.
The woocommerce_bookings_remove_inactive_cart_time
filter allows you to increase or decrease this time. The example below reduces the time to 30 minutes:
Note: If this time is reduced to just a few minutes, then it is possible a booking may be removed from a customer’s cart before they complete checkout. The lowest recommended time is 15 minutes.
Enable Big Selects to fix MAX_JOIN_SIZE errors
↑ Back to topSometimes shared hosts have a low threshold for MAX_JOIN_SIZE, which causes problems with WooCommerce Bookings and WordPress in general. This example fixes that in most cases:

Additionally, Bookings has templates that can be overridden for a more customized approach.
Forward Booking Details to External Site Upon Confirmation
↑ Back to topTo forward booking details to an external site upon confirmation, you’ll need to make an API call to create a post on the external site. There is a WooCommerce Bookings hook to make these API calls. Please note that here we do not cover the specifics of making API calls to external sites.
The woocommerce_booking_{new_status}
hook can be utilized to send booking details to an external site. This hook includes two parameters: $booking_id
and the $booking
object. It is triggered whenever a booking status changes.
Here’s an example of how to use this hook to pass the booking ID and booking object to a function, which can then be used to make an API call to create a post on the external site:
add_action( 'woocommerce_booking_confirmed', 'add_booking_to_other_site', 10, 2 );
function add_booking_to_other_site( $booking_id, $booking ) {
// API call here based on the received $booking_id and $booking
...
}
