Usernames/AdminNames - Stop people from using certain ones, and stop people from having the same names

[fuzzyDCR]

So today some people decided to have some fun on my game and everyone changed there name to the same...Like 15 people...I tried to figure out a way to stop this from happening and couldn't figure it out. Any help would be great. I would also like to be able to prevent people from using certain names in general, or even have certain words in there names...Like Admin...Right now i have the name ADMIN blocked, but can't figure out how to make it so they cant put stuff like Admin-Brad, or Admin-God, or Adminsdeath. Any help if great enough will be compensated.

In preferences, for the username change, and register

Just do a simple query to chekc if the name is taken

Ten a simple if to check it, if its taken tell them, kill the script.

firstly i would stop people from using names already in use like this

 

if($db->num_rows($db->query("SELECT `userid` FROM `users` WHERE `username`='$_POST[username]'"))){die('username already in use');}

 

second if you dont want people to have "admin" in there name u should do it something like this

 

if(substr_count($_POST['username'],'admin')){die('Admin is not allowed in your name');}

I understand how, i just can't figure out where. When ever I do anything in the preferences it doesnt work. I tried doing it with wildcard, and the way posted above, and I must be doing it in the incorrect spot.

Yeh, i edited my post, dont use the wildcard, it wont work :/

[bluegman991]

well i cant tell you where cuz i dont know how that page looks but instead of using preferences.php

you could delete that and use a mod i made a while ago account.php

hmmm...I get errors using that code...

Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';' in /home/wereatw1/public_html/account.php on line 44

[Danny696]

Let me put it in laymans....

Oi, you've made me error. Theres a problem with your syntax. I've just checked it, there was meant to be a coma or semi colon (more likely the later), but instead there was a variable. Just to help you its in account.php, and its on line 44.

Mc v2.0.3 has this in preferences

	$check_ex = $db->query('SELECT `userid` FROM `users` WHERE `username` = "'.$_POST['newname'].'"');
   if ( $db->num_rows($check_ex) > 0 ) {
  echo '
This username is already in use.

> [url=""]Back[/url]
  ';
  die($h->endpage());
   }

mwg's bbcode parser is messing up the input and output of my code so you will have to download the zip in my original thread
