Using Rules to Update Content

Jaya,

I found a solution to my problem with help from a training video from Nodeone, which you should be able to find at: http://nodeone.se/en/coding-for-rules-2

In the setup for the Rule I was able to specify an argument to pass, which I set as the node ID.

In my module I used views_get_view_result to identify the node I wanted to update and then accessed the node's variables.

foreach ($summaries as $summary) {

// Load up the summary node so that we can access its data.
$summnode = node_load($summary->nid);
$object = entity_metadata_wrapper('node', $snode);  
$nodetype = $object->type->value();
switch ($nodetype) 
{ 
    case '010_about':
  // Write the data into the summary fields
  $field_firstname = $object->field_firstname->value();
  $summnode->field_firstname[LANGUAGE_NONE][0]['value'] = $field_firstname;
  ...
  Other node types are handled in further case groups.

I found that I had to use the following code to update long text fields:

$field_long_text = $object->field_long_text->value();
$field_long_textv = $field_long_text['value'];
$summnode->field_long_text[LANGUAGE_NONE][0]['value'] = $field_long_textv;

I'd expect that someone would be able to do what I've coded in a more efficient way, but it works for me.

I hope that this helps - the Nodeone training is highly recommended!
