Code

function _jplayer_check_id($id) {

  // We keep track of player IDs generated per request. This ensures that if a
  // player pointing to the same field is shown multiple times on a page, that
  // each player gets a unique ID. This is especially a problem when jPlayers
  // are embedded in hidden content such as View rendered with Quicktabs.
  static $player_ids = array();

  // Add the request time, so if the same player is inserted multiple times
  // AJAX all players are functional.
  $id = $id . '-' . $_SERVER['REQUEST_TIME'];

  // Store a count of the number of times a unique ID is used, and make it
  // unique if needed.

    $id = $id . '-' . $player_ids[$id]++;
  }
