Here is the form cleansing code described in my last entry.  Here’s a PHP function I whipped up to scan the player name field:

function checkPlayer($in) {
  if(strlen($in) < 3) {
    errorForm(”player name must be at least 3 characters ($in)”);
  }
  if(strlen($in) > 15) {
    errorForm(’player name must be between 3 and 15 alphanumeric characters. Your submitted name is greater than 15 characters’);
  }
  if(!ereg(”^[a-zA-Z0-9]+$”, $in)) {
    // oops!
    errorForm(’player name must be between 3 and 15 alphanumeric characters. Your submitted name contained illegal characters’);
   }
}

In my next interactive blogging game entry, it is cookie and file writing time.

Did this post make you go hmm?
