PHPBB Limit User Name Characters

[GoodGuy201]

Hi,
  I am trying to limit the characters that can be used for PHPBB to just letters,numbers,underscore,and dash.  I don't know how i can do this.  I hope someone can help. Thanks!

ask on phpbb forums, plenty of hacks and other modders there.

A little example for you to see how it works.

but i agree you should use the forum from the provided code as jenk said.


letters,numbers,underscore,and dash are all clased as a charecter.

[code]
<?php

$name="redarrows";

$lenth=strlen($name);

if($lenth > 8){

echo "sorry the name is to long your using $lenth charecters but there should only be 8";

}else {

echo "name lenth ok your useing $lenth charecters";

}
?>
[/code]
