RegEx

[NeoPlosive]

I'm doing a recoding of SourceBans which is a Steam ID banning system for Multiplayer Online Games (released under Creative Commons).

 

I'm a bit useless with RegEx - theres a validation line which validates Steam IDs

 

define('STEAM_FORMAT', "^STEAM_[0-9]:[0-9]:[0-9]+$");

 

Steam IDs are STEAM_x:x:xxxxxxxxx

 

I want to change it so it validates Punkbuster GUIDs instead. These are 32 characters log and alphanumeric.

 

i.e.

 

299f51c289005b05069057e94938afec

3dbacc0e7126a796c60834b832526c49

 

Any suggestions?

This may have been one Google Search too soon!

 

^[a-zA-Z0-9]+$ seems to do the trick - going to test it properly and will post if any problems.

If you want to match exactly 32 characters you can do it like this (assuming your regex library supports this syntax):

 

^[a-zA-Z0-9]{32}$

They're hexadecimal - you don't need g-z

Both very good points!

 

Shall give the {32} a try.

 

I would have tweaked, eventually, getting a bit tired of coding now been doing it all day.
