This module provides a simple way to create forms and questionnaires.

Code

function webform_webform_submission_render_alter(&$renderable) {

  // If displaying a submission to end-users who are viewing their own
  // submissions (and not through an e-mail), do not show hidden values.
  // This needs to be implemented at the level of the entire submission, since
  // individual components do not get contextual information about where they
  // are being displayed.
  $node = $renderable['#node'];
  $is_admin = webform_results_access($node);
  if (empty($renderable['#email']) && !$is_admin) {

    // Find and hide the display of all hidden components.
