Mysql

(1/5) > >>

ben build:
This is quite a big request but would it be possible to have a mysql option which makes it use mysql for users, groups and bans instead of txt

I run multiple servers and i don't want to have to write my own admins system to accommodate this, I know there is the uban system but it doesn't seem to integrate very well.

spbogie:
There is no need to write an entirely new admin mod just to get your users through SQL. You can just write a module for ULib and call ULib.ucl.addUser and ULib.ucl.addGroup. Full documentation of the ULib developer library can be found at http://www.ulyssesmod.net/docs.
One small note on making it a module however, you should only put a small init script in lua/ULib/modules/ as it will be run on both client and server. Put all the functionality and configuration in (a) separate file(s) located elsewhere.

I do not personally have the time right now to create this myself (finals and such), and I know Megiddo and JamminR have been quite busy lately as well, but we encourage you, or anyone else, to attempt. We wrote ULib for everyone, not just us, to use. If you take up this project, we would greatly appreciate it if you would release it here. If you can't/don't want to try this, and no one else picks it up, you will have to wait until we have time.

Megiddo:
We're pulling the users for all our servers from these forums with just a few lines of code. :)

JamminR:
I personally don't know SQL, but as spbogie said, don't have time to learn either.
Megiddo, mind sharing those few lines of code for pulling from our db, minus PW and servernames/etc. Or would that open us to risk?
I've always been curious what it looks like. Might help Ben on his way.

Ben,
As for UBan, Other than it using different commands, why would it be more difficult than what you wish now?

Megiddo:
Obviously this only works for SMF forums, but maybe it will help you. The grants is based off the group IDs assigned by the forums. This is more than my previously stated few lines of code because of the MySQL wrapper, which was grabbed from UBan (and not really entirely necessary). The only function of substance is CheckUser().
