XF 1.4 How to disable numbers usernames

[AscalonCZ]

Hello guys, can you please help me with username registration. I want disable registration users with only numbers in username like 12547951. If they have for example Dan45, Asterix77 it is OK, just clear numbers registration.

You just need to set the username regex to match one non-number character:

[^0-9]

 

[AndyB]

This is what I use:

^[a-zA-Z0-9]+$

This allows all alphabet characters and numbers, but it also allows only a number. How would I use what I have and disallow just a number?

 

[Paul B]

If you mean to prevent any numeric characters, use ^[a-z]+$

 

[AndyB]

If you mean to prevent any numeric characters, use ^[a-z]+$

I mean the following:

Allow
Brogan

Allow
Brogan1234

Disallow
1234

 

[AscalonCZ]

Andy B version is correct, i want allow numbers in usernames, but not ONLY numbers.

 

[AscalonCZ]

Is there any option?

 

[Jashugan]

I'd also like to know this please. Since obviously no real user will just be using numbers.

Admin CP -> Home -> Options -> User Registration -> User Name Match Regular Expression

Alpha only:

^[a-zA-Z]+$

Alpha+space only:

^[a-zA-Z ]+$

Alphanumeric only:

^[a-zA-Z0-9]+$

Alphanumeric+space only:

^[a-zA-Z0-9 ]+$

Alphanumeric+space+underscore only:

^[a-zA-Z0-9 _]+$

Alphanumeric+space+underscore+dash only:

^[a-zA-Z0-9 _\-]+$

 

[Jashugan]

Cheers for that, although I don't think those would do what we were looking for exactly.

I think the OP was looking to allow letters and numbers, but disallow if ONLY numbers.

I think the OP was looking to allow letters and numbers, but disallow if ONLY numbers.

Mike's regex should work for that, though it doesn't explicitly say what the character range is, only that one must not be a number.

This is more explicit... this is alphanumeric only with at least one alpha somewhere:

^[a-zA-Z0-9]*[a-zA-Z][a-zA-Z0-9]*$

Or you may want to allow spaces also:

^[a-zA-Z0-9 ]*[a-zA-Z][a-zA-Z0-9 ]*$

 

[AscalonCZ]

^[a-zA-Z0-9]*[a-zA-Z][a-zA-Z0-9]*$

Thank you Jake, this is what I am looking for, excellent work.

Hmm. My mistake. I referred you to this thread. But now I see in the code that the username regex uses an "i" flag which makes it case-insensitive:

library/XenForo/DataWriter/User.php

Removing the i would allow the regex to be case-sensitive, but that requires a file edit or addon.

			$matchRegex = $this->getOption(self::OPTION_USERNAME_REGEX);
			if ($matchRegex)
			{
				$matchRegex = str_replace('#', '\\#', $matchRegex); // escape delim only
				if (!preg_match('#' . $matchRegex . '#i', $username))
				{
					$this->error(new XenForo_Phrase('please_enter_another_name_required_format'), 'username');
					return false;
				}
			}

so cannot be resolved without plugin?

 

[Robert9]

[A-Z]{1,1}[a-z0-9\-\.]{3,14}

So this will still take "name" instead of "Name"?

Is there a hook around this register test?
Can i add some php code before?
I would like to delete spaces and everything that is not allowed, set all to lower case and a ucfirst, bevor the regex starts.

yap i wonder why is not resolved in default option inside xenforo

My changes in vb > register.php from 1912:

       // fix extra whitespace and invisible ascii stuff                                                                       
        $username = trim(preg_replace('#\s+#si', '', strip_blank_ascii($username, ' ')));

        for($x=0;$x<4;$x++) {                                                                                                                       
           $username = str_replace($array_1[$x],$array_2[$x],$username);                                                       
       }
      
       // Only one!
       $username = str_replace("--","",$username);
       $username = str_replace("..","",$username);
       $username = str_replace("__","",$username);
      
       $username = str_replace("._","",$username);
       $username = str_replace(".-","",$username);
       $username = str_replace("-_","",$username);
       $username = str_replace("-.","",$username);
       $username = str_replace("_-","",$username);
       $username = str_replace("_.","",$username);       
      
        
       // Ucase first                                                                                                 
       $username = ucfirst($username);

For shure an addon would be nice, but it is not done in 2 minutes like changing the code,
what can i do.
