Display a set_message for each bad wor found in string

Rough try, not tested see if it will get you started.

Old saying get it to work first then throw in all the bells and whistles.

PHP Code:

class MY_Form_validation extends CI_Form_validation {

    public function badword($string)
    {
        // Dummy words
        $badWords = array("ban","bad","user","pass","stack","name","html");

        $badFound = '';
        $badCount = 0;

        $matches  = array();
        $matchFound = preg_match_all("/\b(" . implode($badWords,"|") . ")\b/i", $string, $matches);

        if ($matchFound)
        {      
              $words = array_unique($matches[0]);
              
              foreach($words as $word)
              {
                  $badFound =. $word . ' ';
                  $badCount++;
              }
              
              if ($badCount == 1)
              {
                  $this->set_message('badword', 'Your message has a band word <b>' . $badFound . '</b>you can not use that word.');
              }
              else
              {
                  $this->set_message('badword', 'Your message has a band words <b>' . $badFound . '</b>you can not use those words.');
              }

              return false;        
        }
        else
        {
            return true;
        }
    }
}
