function taxonomy_feeds_atom_rdf_map_alter in Feeds Atom 6

Implementation of hook_feeds_atom_rdf_map_alter().

We implement this hook on behalf of the taxonomy module so that we can lazy-create terms as needed. We only do so if the vocabulary the term is in already exists. If the vocabulary doesn't exist, the incoming term is ignored.

Parameters

$target_item: The node that we are creating/editing.

$source_item: The parsed data array from the feed.

Return value

unknown_type

File

./feeds_atom.module, line 64

Contains the main functionality for feeds_atom.

Code

function taxonomy_feeds_atom_rdf_map_alter(&$target_item, $source_item) {
  if (empty($source_item['rdf']['taxonomy']) || !is_array($source_item['rdf']['taxonomy'])) {

    // Nothing to process
    return;
  }

  // Zero out the taxonomy data that is already there, as it will break if we
  // try to save the node with it there.
  $target_item->taxonomy = array();

  // Process the term data.
  foreach ($source_item['rdf']['taxonomy'] as $source_term) {

    // Add new terms if they don't exist
    $vid = NULL;
    $tid = NULL;

    // Find the vocabulary.

      // Features intergration: Features stores vocabulary machine name's in
      // module key prepended with features_
      if (module_exists('features')) {
        $machine_name = !empty($source_term['machine']) ? $source_term['machine'] : $source_term['vocabulary'];

        // Add in features_ if doesn't exist
        if (strpos($machine_name, 'features_') !== 0) {
