Suggested Additional Functions

Hi,

I wrote a small module to allow for previous / next links using a nodequeue as the list. I added the following functions, which I think would be helpful in further development of Nodequeue in general.

/* Get the nid based off position */
function nodequeue_position_nid($sqid, $position) {
  return db_query("SELECT nid FROM {nodequeue_nodes} WHERE sqid = :sqid AND position = :position", array(':sqid' => $sqid, ':position' => $position))->fetchField();
}

/* Return the number of elements in the nodequeue. */
function nodequeue_count_elements($sqid) {
  return db_query("SELECT MAX(position) FROM {nodequeue_nodes} WHERE sqid = :sqid", array(':sqid' => $sqid))->fetchField();
}
