You should be able to do that using a plugin. Maybe there even are already such plugins available on JED.
Personally I don't see the need for this in core.

Actually I fully understand this request - especially after my presentations on "Whats my name" https://www.youtube.com/watch?v=P0m1hqyQlTQ

It makes perfect sense to me and I agree that this would be an improvement

I would look at creating something very similar to the password validation options /Applications/MAMP/htdocs/featured/libraries/cms/form/rule/password.php

@Bakual : Unfortunately, there is NO such a plugin can do this. I had already searched JED for many times in recent YEARS, but never find a plugin can do this.

Big components such as Community Builder has similar feature to limit "username" field, if this field was created by CB itself. But, why I need to install such a big component when I just want to limit the username pattern ? So the answer is still "no".

Hope someone will add this feature to Joomla core.

Thank you.

So this seems to me that what you're asking is a new rule for validating the username field in the same logic like the one that exist in password field.

• https://github.com/joomla/joomla-cms/blob/staging/libraries/cms/form/rule/password.php
• https://github.com/joomla/joomla-cms/blob/staging/administrator/components/com_users/config.xml#L132-L173
• https://github.com/joomla/joomla-cms/blob/staging/administrator/components/com_users/models/forms/user.xml#L23

Thats what I am thinking

If you want to add that, you would have to make it optional. Because a username like "Thomas Hunziker" is perfectly fine for most sites, as well as "André" or "Hämpu" or "email@domain.com".

Yes that is why I suggested doing it just like the password rules we added
that by default have no effect on an existing site and a site owner would
have to make a setting before anything would change.

Yes, this new feature should be "optional". Maybe some Admin would like to allow empty spaces in "username" value, but I personally do not want it, I perfer to replace empty space character with _ or - characters.

Just my two cents: shouldn't we reconsider the whole registration/(user)name stuff at all. For example email and password confirmation or using a username at all is very "old school" today. A lot "modern" pages offers a very short registration form: name/email/(some: confirm email)/password (one time). The username is replaced by the email, password has to insert just once etc.
If we rebuild the username stuff, perhaps we can rebuild the whole process and have a more flexible registration form in the core (at the moment I have to override the whole form with a plugin)

I think that is a topic for another time and not in this issue - perhaps
for Joomla 4

my2cent: The core should not care about features which are not necessary and can be easily realised via 3rd party plugins.

This is very necessary if you watch the video I linked to.

But if you know of a plugin that will allow username restrictions such as
character set etc then please post here

At the moment I don't know of a plugin and maybe it is because there is no urgent need?
I agree that the feature is useful. But I also think that we should keep the core slim. It's always juggling.

We are talking about one (possibly) two files and a few optional parameters

It should be possible easily with a plugin to check the username Server-Side after the form is sent. I'm surprised there is no such plugin available.
I think you can't add Client-Side (JavaScript) validation using a plugin. At least it's harder to do.

Maybe AJAX validation can make it faster?

seems to me a valid request, if someone has time to code it, go for it, I would press the merge button if it is ready and tested :-)

and the benefit of this proposal will be... ?

I think the premise is wrong:

we Admin do NOT want to allow usernames in other languages except English

We admin who?

Any (valid) issue such as using usernames in URLs should be handled differently (like e.g. not using user names at all in URLs and file names, also for security reasons)

If you have such a will and need, no problem, you can roll your own plugin for that. Others may have very different needs from yours...

... my 2c ...

Edit: Admittedly for a special case, but here is a plugin for imposing restrictions on usernames (that can probably be used as a starting point for something "custom"): http://www.joomdle.com/download/category/27-plugins-additional

Edit 2: At least one of my sites will be broken by such a "feature" probably together with numerous more as "email for username" seems to to be quite a popular plugin category

Actually a plugin appoach is possible: https://github.com/joomla/joomla-cms/blob/staging/libraries/joomla/user/user.php#L778-L788

Maybe we could add something like for password in the user's config: https://github.com/joomla/joomla-cms/blob/staging/administrator/components/com_users/config.xml#L132-L173
to:

• minimal length
• limit character
• ...

Yes, possible, and IMHO it belongs to here: https://github.com/joomla-extensions/

(I was so happy when the roadmap announced a Weight Watchers (tm) cure for Joomla...)

I did implement a 'usernamecheck' plugin and a PR: Issue 9943
First time I contribute... thought the PR should appear here but...

Thank you framontb , hope you will polish your code to perfectly solve this
issue.

Maybe you can add a new option to "reserve some strings", for example, do
not allow registration for "CEO", "administrator", "president", "f**k".
