error in the view entry page

[abidfakhrealam]

I'm encountering an issue with my MRBS. I modified the mrbs_auth.inc file is to open so all users can view the meeting details when viewing an entry. Here's the snippet of code I modified:

case 'view_entry.php':
  $result = 0;
  break;

However, when a meeting allows for registration, I'm receiving an error when attempting to view it. The error occurs at the following URL: http://3.19.252.152/view_entry.php?view=day&year=2024&month=3&day=13&area=1&id=5

the error is :

Whoops! Unfortunately MRBS has encountered a fatal error. Please consult your system administrator.

I've now fixed the problem in f89540f.

Are you expecting users who haven't logged in to be able to register? If so, how do you see that working?

[abidfakhrealam]

Yes, we wanted to use the registration process to identify attendees. We only want students to use the registration process to register for the room event program. We do not require students to provide login credentials to make bookings on the platform. They should fill in their details and write their name, course name, and email so that they can register without providing any credentials to the student.

I don't think that would be easy: the registration process only records usernames at the moment.

I think your best bet would be to solve #3635 somehow.
