Class definition of FeedsFeedNodeProcessor.

Class

FeedsFeedNodeProcessor

Creates *feed* nodes from feed items. The difference to FeedsNodeProcessor is that this plugin only creates nodes that are feed nodes themselves.

Code

protected function existingItemId(FeedsImportBatch $batch, FeedsSource $source) {

  // We only support one unique target: source
  foreach ($this
    ->uniqueTargets($batch) as $target => $value) {
    if ($target == 'source') {
      return db_query("SELECT fs.feed_nid FROM {node} n JOIN {feeds_source} fs ON n.nid = fs.feed_nid WHERE fs.id = :id AND fs.source = :source", array(
        ':id' => $this
          ->feedNodeImporter()->id,
        ':source' => $value,
      ))
        ->fetchField();
    }
  }
  return 0;
