[Midas] location of an item

[Patrick Reynolds]

Mona,

First, a bit about how items correspond to files. Items are made up of revisions. Most items contain one revision (the head or latest revision). Within each revision are bitstreams. These bitstreams are analogous to the files on the file system. With all that in mind, the following code should get you what you want (I'm going to assume the item ID is in a variable called, appropriately, $itemId.):

// Load our models
$ItemModel = MidasLoader::loadModel('Item');
$ItemRevisionModel = MidasLoader::loadModel('ItemRevision');
$BitstreamModel = MidasLoader::loadModel('Bitstream');

// Get the item and its last revision from the time id
$itemDao = $ItemModel->load($itemId);
$lastRevisionDao = $ItemModel->getLastRevision($itemDao);

// loop through the bitstreams and print their paths
foreach($lastRevisionDao->getBitstreams() as $bitstreamDao)
  {
  print($bitstreamDao->getPath());
  }

Hope that helps! 

Thanks,
