I used the wrong filter…

but I have one more problem. How to get post id of saved post in this action?
$_POST[‘ID’] – it does not work.

add_action('acf/validate_value/key=field_5e85a3ad796cf', [$this, 'acfValidateCode'], 10, 4);
  public function acfValidateCode($valid, $value, $field, $input_name)
  {
    if( $valid !== true ) {
      return $valid;
    }

    $results = apply_filters('check_promo_code', $value);

    if ($results && $results[0]->post_id != $_POST['ID']) {
      $valid = 'Taki kod promocyjny już instnieje.';
    }

    return $valid;
  }
