Tweaks signatures in ways inspired by other traditional forum software:

Code

function signature_forum_user($op, &$edit, &$account, $category = NULL) {

  // Re-route the user signature to this module's signature table.
  switch ($op) {
    case 'submit':

      // Check if the signature is set in the form
      // (#276349 - Signature deleted when editing profile).
      if (!isset($edit['signature'])) {
        break;
      }

      // If the user has a signature set update it, otherwise create a new entry.
      if (db_result(db_query("SELECT uid FROM {users_signature} WHERE uid = %d", $account->uid)) != '') {
        db_query("UPDATE {users_signature} SET signature='%s' WHERE uid = %d", array(
          $edit['signature'],
          $account->uid,
        ));
      }
      else {
        db_query("INSERT INTO {users_signature} (uid, signature) VALUES (%d, '%s')", array(
          $account->uid,
          $edit['signature'],
        ));
      }
      unset($edit['signature']);
      break;
    case 'load':
      $signature = db_result(db_query("SELECT signature FROM {users_signature} WHERE uid = %d", $account->uid));

      // Bug #190446 OG puts $account->signature into comments.
      $account->signature_forum = $signature;
      break;
    case 'validate':
      $settings = variable_get('signature_forum_settings', signature_forum_defaults());

      // If the signature contains too many lines.
      if ($settings['signature_forum_line_limit'] > 0 && substr_count($edit['signature'], "\n") > $settings['signature_forum_line_limit']) {
        form_set_error('signature', t('Maximum number of !max_lines lines allowed in signature exceeded.', array(
          '!max_lines' => $settings['signature_forum_line_limit'],
        )));
      }
      break;
  }
