 * I am trying to create a profanity filter for gravity forms but the doucmentation
   about their addon frame work is not clear I downlaoded the sample code for sample
   addon and adapted it i am using a filter in my function php to keep out profanity
   and key words from my contact form my question is in gravity forms how do i add
   the filters code i am using the sample addon code provided by gravity forms
 * `/*
    * Use an array to search a string * Allows us to pass the stop words list
   and our post data */ function bld_strpos_arr($haystack, $needle) { if(!is_array(
   $needle)) { $needle = array($needle); } foreach($needle as $what) { $pos = stripos(
   $haystack, $what); if( $pos !== false) { return true; } } return false; }
 * /*
    * Our bad words validation function */ add_filter(‘gform_validation’, ‘bld_custom_validation’);
   function bld_custom_validation($validation_result){ $form = $validation_result[“
   form”];
 *  $stop_words = array(
    ‘outsource’, ‘Sir/Madam’, ‘Sir/ Madam’, ‘Sir / Madam’,‘
   Sir /Madam’, ‘long term relationship’, );
 *  $stop_id = array();
 *  foreach($_POST as $id => $post)
    { if(bld_strpos_arr($post, $stop_words)) { /**
   We have a match so store the post ID and initiate validation error */ $stop_id[]
   = $id; } }
 *  if(sizeof($stop_id) > 0)
    { $validation_result[‘is_valid’] = false;
 *  foreach($form[‘fields’] as &$field)
    { foreach($stop_id as $id) { $the_id = (
   int) str_replace(‘input_’, ”, $id);
 *  if($field[‘id’] == $the_id)
    { $field[‘failed_validation’] = true; $field[‘validation_message’]
   = ‘Please do not send us unsolicited messages’; } } } }
 *  //Assign modified $form object back to the validation result
    $validation_result[“
   form”] = $form; return $validation_result;
 * }’
 * My Quesiton is how do i add this to the plugin code of below
    ‘<? /* Plugin Name:
   Gravity Forms PayPal Add-On Plugin URI: [http://www.gravityforms.com](http://www.gravityforms.com)
   Description: Integrates Gravity Forms with PayPal, enabling end users to purchase

   protected $_title = ‘Profanity Filter Gravity Forms’; protected $_short_title
   = ‘Porfanity Filter Gravity Forms’;
 *  private static $_instance = null;
 *  public static function get_instance() {
    if ( self::$_instance == null ) { self::
   $_instance = new self; }
 *  return self::$_instance;
    }
 *  public function plugin_page() {
    ?> This page appears in the Forms menu <?php}
 *  public function form_settings_fields() {
    return array( array( ‘title’ => ‘Simple
   Form Settings’, ‘fields’ => array( array( ‘label’ => ‘My checkbox’, ‘type’ =>‘
   checkbox’, ‘name’ => ‘enabled’, ‘tooltip’ => ‘This is the tooltip’, ‘choices’
