I am trying to node_save($node) in different database. Second DB is clone of first DB.

its the part of Archive old content data in different database

I am trying with following code

  $node = node_load($nid);

But its not working. Is anything i am doing wrong ?

i want to use node_save because in my node, number of fields, field_collection, entity_refrences are available.

  • Have you try to read the data from that new DB, does it work?

  • hi @Namari : Yes, i am able to read the data from my newDB. Feb 3, 2016 at 10:32
  • One thing i also noticed, i am able to update node. Means same node if exist in both db and i have updated in default db then its updating in 'archive_db' using above code. But its not working if node is not present in ''archive_db'. Feb 3, 2016 at 11:32
  • Try this: unset($node->nid); $node->is_new = true; have you tried entity wrapper?

Try this, it was working for me:

$nid = '2841';
$item_ids = array();
$node = entity_load('node', array($nid), array(), true);
foreach ($node[$nid]->field_COLLECTION_NAME[LANGUAGE_NONE] as $key => $value) {
    $item_ids[] = $value['value'];

//load the field collections
$fc_item = entity_load('field_collection_item', $item_ids);

//change db

$clone = new stdClass();
$clone = clone $node[$nid];
$clone->is_new = true;

//save node so we can use the new nid to link the field collection
entity_save('node', $clone);
//gives you the nid of the new node created

//save the field collections
foreach ($fc_item as $key => $value) {
    //unset values
    $value->is_new = true;
    $value->revision_id = NULL; 
    $value->item_id = NULL;
    //link it to a node
    $value->setHostEntity('node', $clone);

dsm(entity_load('node', array($clone->nid), array(), true));
//go back to the default DB
  • Are you used field_collections with unlimited value in you entity ? My problem with Field_collections and Paragraph entity values are not saving; Feb 5, 2016 at 12:34
  • Is your field collection in the node_load?

  • same code i already tried , but no luck :( Its not saving the value Feb 5, 2016 at 13:35
  • I've edited, this should work. I had a weird behaviors giving me empty field collection before the one with the data, it disappears once the node is saved though.
