Form_validation: How do I not allow spaces? - El Forum - 12-11-2008

I want users to register a username with no spaces and only allow A-Z and 0-9, no other characters. How do I use the form_validation to make sure the user submits with the rule as stated above?

I just noticed in the form_validation there is:
Code:
function alpha_numeric($str)
{
return ( ! preg_match("/^([a-z0-9])+$/i", $str)) ? FALSE : TRUE;
}
