Regex a user name and append to a URL in template?

[brdad]

Thanks, I think I got it. Part of my problem was trying to do the php in a template instead of a direct exec widget itself.

I did have to split the regex up into two lines. One part has to remove unwanted characters, the other has to remove leading digits, or I have now changed it to add an underscore before leading digits (Still not fully proven, however!)

PHP Code:

$dirty = vB::$vbulletin->userinfo['username'];
$clean = preg_replace('/[^-a-zA-Z0-9_|^{}[\]\\\\]/','',$dirty);
$cleaner = preg_replace('/^([0-9]+)([^0-9])/', '_\\1\\2',$clean);
