Username Registration (A-Z, 0-9 Characters Only)

In Reply to this thread: https://vborg.vbsupport.ru/showthread.php?t=92308

Only accept usernames with no special characters or spaces.

Database query:

Open up PhpMyAdmin, goto to your vbulletin database, run following query:

INSERT INTO setting ( varname , grouptitle , value , defaultvalue , optioncode , displayorder , advanced , volatile )
VALUES (
'az09characters', 'register', '1', '1', 'yesno', '101', '0', '1'
)

Phrases To Add:

Phrase Type: Front-End Error Messages
Varname:     az09charactersonly
Text:        Only  characters A-Z, 0-9 may be used in usernames, no spaces, no special ascii-type letters.

Phrase Type: vBulletin Settings
Varname:     setting_az09characters_title
Text:	     Disallow Special Characters

Phrase type: vBulletin Settings
Varname:     setting_az09characters_desc
Text:        Setting this to "yes" prevents users from using special characters or spaces in there user name.

File Modifications:

Open:

[forumroot]/register.php

Find:

PHP Code:

    // check username does not contain semi-colons
    if (preg_match('/(?<!&#[0-9]{3}|&#[0-9]{4}|&#[0-9]{5});/', $_POST['username']))
    {
        //eval(print_standard_error('error_username_semicolon'));
        eval('$errors[10] = "' . fetch_phrase('username_semicolon', PHRASETYPEID_ERROR) . '";');
    } 


Above that add:

PHP Code:

    // Only A-Z, 0-9 Characters Only */
    if ($vboptions['az09characters'])
    {
        if (!eregi("^[A-Za-z0-9]+$", $_POST['username']))
        {
            eval(print_standard_error('error_az09charactersonly'));
        }    
    } 


Save:

register.php

Now users can not use special chars or spaces in their username when signing up.

To disable the function goto, Admin CP > vBulletin Options > User Registration Options.
Find the yes/no option under ?Disallow Special Characters ?

That's all, Gr3?Tz Untold....

has anyone made this for vb3.5.0 ? I've just wiped 9000 accounts off my site .. and I know many of the accounts will be coming back with the new site. I'd really like to have something like this in place before my new site goes public.
