Guidelines for Updating Node Fields Without node_save() In Drupal

Customization is nowadays common in Drupal site. Here you may need to save node programmatically at any time. For saving node programmatically we use node_save() hook which will save the whole node though we want to update only one field.

A Drupal function field_attach_update() will replace node_save() in some way. It will update only that field which you want to update.

Benefits of field_attach_update()

  1. Reduces load time.
  2. Not update CCK fields.
  3. Easy to use.

Below is the code to use field_attach_update() hook.

// $arr_nids is array of node id that you want to update
$arr_nodes = node_load_multiple($arr_nids);
foreach ($arr_nodes as $key => $node) {
$node->field_fieldname1[LANGUAGE_NONE][0]['value'] = 'field1 value';
$node->field_fieldname2[LANGUAGE_NONE][0]['value'] = 'field2 value';
$node->field_fieldname3[LANGUAGE_NONE][0]['value'] = 'field3 value';

field_attach_update('node', $node);
entity_get_controller('node')->resetCache(array($node->nid));
}

entity_get_controller('node')->resetCache(array($node->nid)) is used to clear cache for the entity.

For example:
