disallow space in username?

Is there a way or a hack to disallow a space in a username? I searched but no luck...

i would like to know that too, as well as other characters like #, %, & * etc.

I want to fliter out any ASCII characters like this as they screw things up. ¿

To complete disallow spaces in usernames:

In register.php, find:

PHP Code:


		
			
  $username = trim($username);

ABOVE add:

PHP Code:


		
			
if (stristr($username,' ')) {

    eval("standarderror(\"".gettemplate("error_nospace")."\");");

    exit;

  }

Then create a new template called "error_nospace" with the contents:

Code:

Spaces are not allowed in usernames.

Not tested, but should work.

thank you so much buddy! I will test it and let you know. I really needed this as my hack I wrote to create an e-mail account in cPanel is hanging Ensim if a member tries to create a mail account with a space in it.. If it works, may I have your permission to add this to the hack install file?

Of course you can.

The other alternative is to force the user to use an underscore rather than a space by doing this - also if it's for email, make everything into lower case:

In register.php, find:

PHP Code:


		
			
$username = trim($username);

Above, add:

PHP Code:


		
			
    $username = strtolower(str_replace(" ","_",$username));

So if I register with the name "Erwin Loh", the system will save it as "erwin_loh". :) You may need to move that line of code higher or lower depending on what you want it to do... play around with it. Again, not tested, but should work...

this is great, but how do i stop special characters altogether? like ! @ # $ % ^ & * ( ) { } [ ] | = - and others

In register.php, find:

PHP Code:


		
			
$username = trim($username);

Under it, add:

PHP Code:


		
			
$username = str_replace(' ', '_', $username);



if(!preg_match('#^([A-Za-z0-9\_]+)$#', $username)) {

  eval("standarderror(\"".gettemplate("error_badusername")."\");"); 

  exit;

}

Then create a template named error_badusername

Code:

The username you have chosen is invalid. It can only contain alphanumeric characters and underscores.

Untested, but it should work :p
