Import files

I would like to be able to import files with the node import. This can be achieved with the following code (I think):

  $file = new stdClass();
  $file->filename = basename($filename);
  $file->filepath = $filename;
  $file->filemime = $mime;
  $file->filesize = filesize($filename);

  $file->uid = $uid;
  $file->status = FILE_STATUS_PERMANENT;
  $file->timestamp = time();
  drupal_write_record('files', $file);
  $file->fid = db_result(db_query("SELECT fid FROM {files} WHERE filepath = '%s'", $file->filepath));

Use case:

I have a directory of files for the letter "k" with about 400 files. Each file corresponds to a dictionary entry. I made a script to merge the results, and a line looks like this:

kátaloga;katalog;s.;0001;words/se/k/0001.mp3;words/nb/k/0013.mp3

Ideally the above code would enable a function for selecting the fifth field for creating the file and return the fid which is needed for inserting in the filefield cck. (At least the latest 5 version of Node Import only lets me give fid to the filefield, and not a filename). All derived filefield fields ask for the fid. So this would work with audio filefield and filefield image.

The same would probably apply for image and audio nodes as well.

For importing images I'm not sure if there needs to be a call for image cache, or if image cache automagically will notice the new images and resize when needed. The same for image.

I looked into the 6.x-1.x-dev files but couldn't immediately see where the field mappings are done.

Best regards,
Paul
