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)) != FALSE) {
        db_query("UPDATE {users_signature} SET signature = '%s', status = %d WHERE uid = %d", array(
          $edit['signature'],
          $edit['signature_default_status'],
          $account->uid,
        ));
      }
      else {
        db_query("INSERT INTO {users_signature} (uid, signature, status) VALUES (%d, '%s', %d)", array(
          $account->uid,
          $edit['signature'],
          $edit['signature_default_status'],
        ));
      }
      unset($edit['signature']);
      break;
    case 'load':
      $signature = db_fetch_object(db_query("SELECT signature, status FROM {users_signature} WHERE uid = %d", $account->uid));

      // Bug #190446 OG puts $account->signature into comments
