Restrict usernames to alphanumeric and underscore
 

This is a vB 3.7 port of the same mini mod.

What is this Plugin about?

Are you tired of seeing in your forums usernames like these?:
1.- The Super Boy (spaces)
2.- my_new_name (underscore abuse)
3.- im?a??nd?b?ar (international characters)

Well, with this simple addon you can prevent that from happening from now on (it can't correct already spoiled usernames). When a user tries to register using one of those chars, a nice error message makes sure the user picks another "normal" name.

Installation instructions
1.- Download the attached .xml
2.- Go to Admin Control Panel => Plugin System => Manage Products => Add/Import Product => and browse for the the location where you downloaded the .xml
3.- Hit Import
4.- To configure it (not really needed, but it is there), go to Vbulletin Forum Options => Restrict Usernames on registration

By default this addon prevents spaces and any char other than numbers and (english) letters while allowing underscore.

**Disclaimer**
This mod is not absolutely necessary as vBulletin allows you to do what this mod does and more from within the Admin Panel:
Admin CP -> vBulletin Options -> vBulletin Options -> User Registration Options -> Username Regular Expression

You only need to use this mod if you don't want to deal with Regular Expressions.

This is already possible in default vBulletin, since 3.6.8 if not sooner.

Admin CP -> vBulletin Options -> vBulletin Options -> User Registration Options -> Username Regular Expression

Which is actually more powerful than your mod is as well.

Thanks GrayMatter,

As you can see from the previous version thread, https://vborg.vbsupport.ru/showthrea...light=restrict
some people are unaware of that feature or they just don't want to deal with Regular Expressions.

Anyway, thanks for the heads up. I will add a disclaimer so people know beforehand that this feature is available from within the ACP as long as they are not scared of RegEx.

thenk yuuu canim :D:up: good job meeen :D:up:

What if my Real name is imçañóndábèar :'(

Great work mate. Thanks.

One of my most favorable mods for vb. Thanks for the update.

Thanks, for so long I have been inputting every other symbol I could think of into the disallowed user names list.

Is this the same as using regular expressions that are built into vB 3.7?

Something like:

In vB options - User Registration Options - Username Regular Expression

Would that have the same effect, or am I missing something about what this mod does?

Thanks!
