Your Moodle version

Activities: Booking

Maintained by it's me David Bogner, Picture of Andraž P. Andraž P.
The module is perfect for managing participants and subscription of online and offline courses and events.
Moodle 2.0, 2.1, 2.2, 2.3, 2.4, 2.5

Attention: This plugin needs funding, otherwise it will be discontinued. The latest version is available for Moodle 3.1, but this will be the last supported Moodle version (if no funding is provided). There are a lot of necessary updates, that need funding in order to keep the  plugin working with future versions. Some of these tasks are

  • PostgreSQL and MSSQL Support is missing
  • Implement automated testing
  • New tagging API is not supported
  • Upgrade from custom availability to Moodle availability API has to be done
  • Replace YUI Javascript framework with JQUERY framework (YUI is not developped anymore)
  • Provide documentation (only a part of the features are documented)
  • Language optimization (German language support is not available anymore )
  • Additional features
This is a powerful booking tool, that provides a lot of features. It is perfect managing course bookings, or bookings of events, that are not associated with a moodle course. Some of the features are:
  • Max participants
  • Waitinglist
  • Automatic course subscription
  • Confirmation mail
  • Download userlist as xls or ods
  • Cancellation system
  • Subscription period
  • Accept terms and conditions
  • Custom messages
  • Bulk subscription management
  • and a lot more.

    Great work with the new update David Bogner. Thank you for adding an option to delete a booking. All seems to be working fine. Keep up the good work.

    With following stack trace error :

    @Anup Srivinas: This problem has nothing to do with the booking module. Please refer to the quiz module or report a general bug in Moodle. None of the lines in debug output is a booking module code.

    Hi David,

    Thanks for adding the Delete option.

    I dont understand the tagging issue you are talking about though. What i wanted to know is if there is a way to add more fields on the Booking report, except for the fields that are from the "Additional Fields" category? I am specifically interested in the user profile fields the under the "Optional" category. e.g. Skype ID, Yahoo ID etc.
    Or maybe there is a way to add these fields using Tags?

    Thank you David for testing to see if you can reproduce the error I am seeing. I am using Moodle 3.1.1. I first installed Booking when the site was running 2.6. We then went to 2.8 and upgraded Booking then.

    The server is Apache 2.4, PHP 5.6 and MySQL 5.6. I have Opcache enabled. Output buffering is set to 4096. I see the same error on a fresh 3.1 site on the same server. Any insight would be appreciated.

    @Rob Johnson: If you look at the post from Anup Srinivas, there seems to be the same problem with the quiz module. Could you test the report page in the quiz module and look, if there is the same error displayed?

    Hi David,
    Quiz results download just fine for me. Also, individual booking options download fine. It is only when I try to download all booking options that it throws the error. Is there a difference in the code between a single booking option and downloading all?

    I turned off output buffering on a dev server and I do not get the error. However, the resulting file is shown in the browser instead of being prompted to download. I would like to keep output buffering on for performance reasons.

    Hi David,
    places/waitinglist places are not shown in the booking overview! Available places are set to 20, waitinglist places to 5. Do I have to consider anything else to get this working?

    I am using the latest plugin version on Moodle 3.1.2+!

    Many thanks in advance!

    Hi David,
    I turned off output buffering temporarily on my production server and the error is cleared. Did you have output buffering turned on when you tried to reproduce the error? Again, it only happens when I try to download all booking option responses. It does not happen when downloading a single booking option. Thank you again for any help.

    Hi Rob,
    I did not have the time to have a closer look at the problem. How did you turn off the output buffer?
    Kind regards,

    @Georg Wiesinger: The reason you are not seeing any places available is, because you are using german. German is not supported anymore due to lack of funding. You can nevertheless provide your own translation in the Moodle admin backend or even better on

    @Rob: How many bookings do you have? 10, 1000 or 10000 or 100000 or 1.000.000?

    @David, The output buffer is in the php.ini file. It is set to 4096 bytes by default.

    The export fails for all booking options no matter if there only two or up to 80. If I then click a single booking option, it works fine.
