A Moodle 1.9 version of this plugin can be downloaded directly here: - this is not available on as there would be a lot of work involved in rewriting it to pass the automated database naming checks.

    We have got this installed now and its working really well, but is there any way to stop the repeat function? We have staff who need to know when events are happening and the repeated events or getting overlooked.

    I've set the repeat options to 1 so that staff can't actually make a repeat booking but it doesn't overly tell them why they can't make that booking when they try to. Is there any way to hide the text so that it doesn't show repeat bookings as being an option?

    Many thanks

    There is no built-in way to do that, but you may be able to hide the elements by adding some custom CSS to your theme.

    People struggling with "repeat" bookings returning with a booking conflict with a date of 1970 change line 326 of web/mrbs_sql.php from $entrys = ''; to $entrys = array();

    Worked for us

    @Overnet Data - if that's a bug fix, could you post it on github (via the 'source control URL' linked above) or, even better, submit it as a patch (via github) and I can look at integrating it properly. It would be helpful it you gave clear instructions about how to reproduce (I've not tried yet).

    Sorry mate...
    Upgraded to Moodle 3.4.
    During database upgrade and afterwards it comes up with this error a lot of times..

    Invalid admin setting (auth_ldap/mrbs-admincontext)

    Sadly .. it also seems to break moodle in a lot, especially in other site administration tasks too.

    It seemed to work fine in 3.3 ... so it appears that something about 3.4 is not handling errors very well either...

    I am going to have to go back to 3.3.. Have tried the upgrade twice with the same problem..

    Pity .. as 3.4 has a new module to convert to https...

    Looks like there's a new restriction in Moodle 3.4 about characters such as '-' appearing in config settings. I'll look into it when I have a chance, but I'm not sure when that will be.

    Hi Peter - sorry for the slow reply. The error you have reported is not really related to the MRBS plugin. It seems you have created a role called 'mrbs-admin' (shortname) and that is causing a problem with auth_ldap, which generates its config names from role shortnames (and, hence, is creating the invalid setting).

    You should be able to fix this by renaming the role to 'mrbsadmin' instead of 'mrbs-admin' (note that 'mrbsadmin' is the name used by default when installing block_mrbs).

    Sorry about the delay.

    Correct you are.

    Changed the role name to default and upgraded to Moodle 3.4.2+ (Build: 20180421) and have no problems.

    Many tx for the fix.

    First of all congratulations for this useful moodle block.

    Until now it has been working perfectly to me but I've just installed Moodle 3.5 and I can't get booking multiple reservations (nor by date, nor by n-weekly).

    Any idea?

    Since 3.6 there seems to be an issue with multiple entries. When I try (as admin) to book a repeating entry, the system puts the beginning date to 1970. There is no way to change that :/

    Estou utilizando no 3.7. O único problema que tenho encontrado é com relação às recorrências. Elas simplesmente não funcionam. Mas para demais funções está OK.

    Hi, I tried to install the latest code of the plugin in moodle 3.7.2. During database update I receive an error, but installation finishes. A a role only mrbs viewer ist installed. Trying to manually create the roles admin and schedulers leads to the problem that block/mrbs:administermrbs and block/mrbs:editmrbs are missing.
    Has anyone succeded in installing an using this plugin with moodle 3.7 ?
