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

This is my first post and I'm jumping in head first so please bear with me.

I want to format a user name removing unusable characters, and then append that user name to a URL for IRC chat. I'm not 100% sure I can do this in a template for a widget nor am I 100% sure how to code it. Any help would be appreciated. I know the code below is wrong, but it should be clear what I am trying to accomplish.

Thanks

PHP Code:


		
			
<div class="cms_widget"> 

  <div class="block"> 

    <div class="cms_widget_header widget_header"> 

       <h3>IRC Chat</h3> 

    </div> 

  <div class="cms_widget_content widget_content"> 



      Dirty = $bbuserinfo[username]



      $Clean = preg_replace('/^[0-9]+([^0-9])/', '\\1', preg_replace('/[^-a-zA-Z0-9_|^{}[\]\\\\]/', '', $Dirty));}



      $Output = 'http://www.somesite.com/chat&user='$Clean

  



    </div> 

   </div> 

</div>

PHP Code:


		
			
$cn = preg_replace('/^[0-9]+([^0-9])/', '\\1', preg_replace('/[^-a-zA-Z0-9_|^{}[\]\\\\]/', '', $bbuserinfo["username"]));

$output .= '<a href="http://www.somesite.com/chat&user='.$cn.'">Join Chat!</a>';

try this

no guarantee on that regex operation tough, looks unnecessarily complicated.

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);

For what it's worth, you could do this:

PHP Code:


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

Sorry, it seems the PHP tags don't want to size the box properly above.
