• After somebody submits a webform, he should be redirected to the "webform result" (which is standard generated, but only accessible by clicking the "webform results" tab as an admin).
  • My module needs to hook into the "webform results", and add some simple custom PHP calculations on top of that "webform result" (for example: if two radio-elements have a certain value, a warning is displayed on top of that result page)

Any ideas ?

You have do some customization for this, use hook_form_alter().

  1. Create a custom module.
  2. Create a result page in that module.
  3. Alter the webform.
  4. Do the calculation.
  5. Sent the data to result page and show.


function  MODULE_NAME_form_alter(&$form, &$form_state, $form_id) {
  if (strpos($form_id, 'webform_client_form_') === 0) {
    // webform_client_form_ (change this id with your form id)

   $form['#submit'][] = 'changeform_form_submit';


function changeform_form_submit($form, &$form_state) {
  ... your submission logic ...
  • 1) Hi. Would it be better that after submission, the user redirected to node/<nid>/submission/<sid>? Here is all the submitted content visible. 2) Is this a better hook to use : webform_submission_page() ? Then I can add custom PHP text to this variable : $output = drupal_get_form('webform_client_form_' . $node->nid, $node, $submission);
