Code

function swftools_set_size(&$vars, $player = array()) {

  // Not a pretty piece of code, but should be ok for the moment. We are
  // purposefully passing the width and height
  // if we have them. Unsure if this will cause problems with some players.
  // It's an ugly piece of code, but will remain in this form until a clearer
  // solution arises.
  //
  // It may be that, in hook_swftools_methods, the flash player indicates that
  // it *want* certain values copied b/t params and flashvars.
  // The code below was patch to fix notice errors, but it broke flash node autodetect
  // Flash node has been patched to fix this by changing zero height / width to null
  // TODO : Is it really necessary to set the height and width in to the flashvars?
  // If flashvars are empty, but params are set, populate flashvars with params
  if (empty($vars->flashvars['width']) && empty($vars->flashvars['height'])) {
    if (!empty($vars->params['width']) && !empty($vars->params['height'])) {
