Automatically Fill A Form Field With the Node Title

This currently isn't possible without custom coding (as far as I know). The only way I can think of doing it is using the additional processing code to check the current URL, loading the node, then setting the value of a field. However I don't provide support on how to write custom code in the Webform issue queue. See http://drupal.org/handbook/modules/webform/submission-code

Try something like this in the "additional validation" processing block:

<?php
$form_values['submitted_tree']['your_field_name'] = $node->title;
?>

try the prepopulate module http://drupal.org/node/228167 - i've found it very handy, though i haven't used it with webform - but it's supposed to work see http://drupal.org/node/587306

I solved it by using a hook_form_alter() in my custom module. It looks like this:

/**
* Implementation of hook_form_alter()
*/
function YOURMODULE_form_alter(&$form, &$form_state, $form_id) {

switch ($form_id) {
    case 'webform_client_form_YOURWEBFORMID':
      if(arg(0)=='node' && is_numeric(arg(1))) {
      $node = node_load(arg(1));
      // Add the node title to the webform field      
      $form['submitted']['YOURFIELD']['#default_value'] = $node->title;
      }
      return $form;
    break;
  }
}

If additional processing does it, I would go for that instead.

You can find YOURWEBFORMID by doing a dpm($form_id); before switch ($form_id) { if you have the Devel module installed. Or just use print_r($form_id);

In my case I had a hidden field with the node title inserted.
