Allow users to book maximum x number of events per day - per week - per month per calendar

[MNRKLK]

Hello!
This is a great work that you have done here!
I would like to know if using a custom code or perhaps you could include this in an update if useful for others, to be able to block the users from booking more than x number of events per day, per week or per month per calendar
For instance: 1 user can maximum book 2 events a day for calendar A, the same user can maximum book 1 event a day for calendar B, the same user can maximum book 1 event a week for calendar C
This case could be useful in case of subscriptions and not letting people book all the events in a day.
Thank you!

Hello,
Thanks a lot!

This feature has been requested, I add your vote, thank you.

I will post a custom code here for reference (you will need to adapt it to your needs, and maintain it) using the bookacti_validate_booking_form hook.

The code below allows a logged-in user to book a maximum of 2 distinct events per month, and 10 bookings per month.

This code is to be added in your child theme functions.php or with Code Snippets:

EDIT:
2021-05-14 - Compatibility with Booking Activities 1.9 and more. Now works with groups of events. Count the bookings quantity instead of distinct bookings. Do not count events already booked.
2023-01-27 - Compatibility with Booking Activities 1.15.6 and more.

// Restrict the number of bookings / booked events per user per period (per month in that example)
function my_theme_restrict_number_of_bookings_per_period( $validated, $picked_events, $args ) {
	// Don't check if the booking is already refused 
	if( $validated[ 'status' ] !== 'success' ) { return $validated; }

	// Doesn't work for non-logged-in users
	$user_id = get_current_user_id();
	if( ! $user_id ) { return $validated; }

	/****** SET THE MAX VALUES HERE *****/
	$max_bookings_per_month = 10;
	$max_booked_events_per_month = 2;
	
	// Keep one entry per event, not per group
	$picked_events_single = bookacti_reconstruct_picked_events_array( $picked_events );
	
	// Check if each picked event can be booked according to the per-period restrictions
	foreach( $picked_events_single as $picked_event ) {
		// First day and last day of the picked event month
		$first_day_of_month = new DateTime( $picked_event[ 'start' ] );
		$first_day_of_month->modify( 'first day of this month' );
		$last_day_of_month = new DateTime( $picked_event[ 'start' ] );
		$last_day_of_month->modify( 'last day of this month' );

		/****** SET THE PERIOD HERE *****/
		$from = $first_day_of_month->format( 'Y-m-d' ) . ' 00:00:00';
		$to = $last_day_of_month->format( 'Y-m-d' ) . ' 23:59:59';

		$filters = bookacti_format_booking_filters( array(
			'templates' => false,
			'user_id' => $user_id,
			'from' => $from,
			'to' => $to,
			'active' => 1
		));
		$bookings = bookacti_get_bookings( $filters );
		
		// Count bookings and booked events
		$bookings_nb = 0;
		$booked_events_uid = array();
		if( $bookings ) {
			foreach( $bookings as $booking ) {
				$bookings_nb += $booking->quantity;
				$booked_events_uid[] = $booking->event_id . '_' . $booking->event_start . '_' . $booking->event_end;
			}
		}
		
		// Add picked events to booked events count
		$from_dt = new DateTime( $from );
		$to_dt = new DateTime( $to );
		$picked_events_uid = array();
		foreach( $picked_events_single as $future_booked_event ) {
			$future_booked_event_start_dt = new DateTime( $future_booked_event[ 'start' ] );
			if( $future_booked_event_start_dt >= $from_dt && $future_booked_event_start_dt <= $to_dt ) {
				$bookings_nb += $args[ 'quantity' ];
				$picked_events_uid[] = $future_booked_event[ 'id' ] . '_' . $future_booked_event[ 'start' ] . '_' . $future_booked_event[ 'end' ];
			}
		}
		// Count only distinct events (if the event was already booked, do not count it)
		$booked_events_uid = array_unique( array_diff( array_merge( $booked_events_uid, $picked_events_uid ), array_intersect( $booked_events_uid, $picked_events_uid ) ) );
		
		// Check if the max number of bookings is reached
		if( $bookings_nb > $max_bookings_per_month ) {
			$validated[ 'status' ] = 'failed';
			$validated[ 'error' ] = 'too_many_bookings_per_month';
			$validated[ 'messages' ][ 'too_many_bookings_per_month' ] = array( 'You can make only ' . $max_bookings_per_month . ' bookings per month.' );
			break;
		}
		
		// Check if the max number of events is reached
		$booked_events_nb = count( $booked_events_uid );
		if( $booked_events_nb > $max_booked_events_per_month ) {
			$validated[ 'status' ] = 'failed';
			$validated[ 'error' ] = 'too_many_booked_events_per_month';
			$validated[ 'messages' ][ 'too_many_booked_events_per_month' ] = array( 'You can book only ' . $max_booked_events_per_month . ' distinct events per month.' );
			break;
		}
	}

	return $validated;
}
add_filter( 'bookacti_validate_picked_events', 'my_theme_restrict_number_of_bookings_per_period', 100, 3 );

Hi!!
Thank you very much! I'll implement it and will let you know.
Kind Regards,

[prosie]

I would like this feature, too. Will try the code in the meantime. Please add my vote! Thank you.

Hello, the code is outdated, it won't work after version 1.8.9, sorry. The bookacti_validate_booking_form hook parameters and return value have changed in 1.9, so this code needs to be adapted.
I have added your vote, thank you.

[prosie]

Thanks for letting me know. Maybe I'll need to find another plugin.

[yoancutillas]

I have updated the code for Booking Activities 1.9 and more.

[antoinepernaud]

Ho Great job !
Is it possible to limit to X booking(s) per activitie ?

[yoancutillas]

Sorry I missed your message. Thank you! Yes, you can adapt this code with your own conditions, this is only an example.

[antoinepernaud]

Sorry I missed your message. Thank you! Yes, you can adapt this code with your own conditions, this is only an example.

Ok thank you

[rayedgar]

I noticed that it won't let you reschedule and throws the same limit message with this code. ($max_bookings_per_month = 1;
$max_booked_events_per_month = 1;) or am i missing something in the code to set? And could i specify an event to limit?

[yoancutillas]

Hello Ray, sorry, this is just an example in the hope to help. You need to customize it to get it working as desired.

[hassounet]

I also need this feature ! will try to figure out custom code in the meantime
