I want to have a computed field pull in the name and content of a field after it has been edited. I would also like the computed field to contain the content that was edited before edit (if that makes sense?). So what code do I need to find which field has been edited?
I also found this in the node_form drupal api:
// Changed must be sent to the client, for later overwrite error checking. $form['changed'] = array( '#type' => 'hidden', '#default_value' => isset($node->changed) ? $node->changed : NULL, );
Is there a way I access this 'changed' value to check if a piece of content has been changed?
p.s. I am new to drupal and php, so stating your answer in simpler terms with more explination is greatly appreciated.
