Redirect to Dynamic URL

By setting the $node->webform['confirmation'] key, you can change where Webform redirects the user after form processing has been completed. Use the code below to change the URL based on your own criteria.

// Redirect to Google when done.
$node->webform['confirmation'] = 'http://google.com';

// Redirect to node 1 (an internal Drupal path).
$node->webform['confirmation'] = 'internal:node/1';

// Redirect to the contents of a hidden field.
$node->webform['confirmation'] = $form_values['submitted_tree']['my_hidden_value'];
