Check if Input Field Contains *insert text here*

[Joshua F]

I have a register script, and I am wanting to make it so that if the username field contains, lets say "mod", "ass", and more, then it'll return an error and wont let them register.

Try the following, just place the banned words in the $bannedWords array...

<?PHP

  $username = 'Peter Ass';

  $bannedWords = array('ass','poop','admin','mod','team','staff');

  if(preg_match('#('.implode('|',$bannedWords).')#i', $username)) {
    echo 'Failed';
  } else {
    echo 'Passed';
  }

?>

 

Try it out and let me know how it goes.
