Computing a field from a view

Your mileage may vary, but here is some code which calculates a field based on a view.

This code may not do what you want— if the view changes (e.g. another node is added), this field would not be re-evaluated till the next time the node is saved.

One (ugly) solution is to put similar code into the header or footer of a view.

This is a coding alternative to the views_calc module, which allows a great deal of flexibility, but is perhaps not ideal.

<?php
$view = views_get_view('YOURVIEWNAME');
$info=views_build_view('items', $view, array($node->nid), false, false);
$total=0;
//drupal_set_message(serialize($info));
foreach ($info['items'] as $item) {
  $total+=$item->YOUR_FIELD_USE_THE_DEBUG_MESSAGE_ABOVE_TO_FIND_IT;
}
$node_field[0]['value']=$total;
?>
