I am trying to set the value for an existing Node Reference drop-down field in a content type via hook_form_alter as part of an AJAX call. The form needs to set values based on a selection, which is does correctly for dozens of fields, but I can't get or find the array structure to change/set the value for a Node Reference field. I've looked around and tried every permutation I can find, including dozens of guesses at what the array structure should look like without any success. Any help would be appreciated.

  • @Neograph734 of what? every permutation I've tried, I didn't track it. I need the array structure to assign a node value to a node reference field

  • Looking at the code I guess that should be an array of nids, like this: array(array('nid' => 1)) (single value field) or array(array('nid' => 1), array('nid' => 2)) (multi value).

  • Node Reference as in provided by the obsolete References module? Or an Entity Reference?

  • it should be an array of nodes, but the exact structure eludes me: for example where a text field would be something like $form['field_name'][LANGUAGE_NONE][0]['value']['#value'] = 'abc', I don't know the corresponding structure and relevant names for a reference field

With Clive's help, I was able to figure out the array structure I needed. To set the node ID for a Node Reference field (References Module) in hook_form_alter, this structure worked for me:

$form['field_name'][LANGUAGE_NONE]['#value'][0] = {node id}
