Code to confirm the e-mail during signups. Since this code is only needed when building or submitting the signup form (or editing an existing signup), it all lives in this include file and is only loaded when needed.

Code

function signup_confirm_email_alter_signup_form(&$form, &$form_state, $form_id) {
  global $user;
  if ($form_id == 'signup_edit_form') {
    $signup = $form['#signup'];

    // Only display the email confirmation fields if an authenticated user is
    // editing their own signup (anonymous signups already provide an email,
    // and we shouldn't confirm email when an admin is editing another signup).
    if (empty($user->uid) || $user->uid != $signup->uid) {
      return;
    }

    // Ensure the user has permission to edit their own signups, or the rest
    // of this is wasted effort for a form that can't be submitted.
    $node = node_load($signup->nid);
    $admin = _signup_menu_access($node, 'admin');
    $own = !empty($user->uid) && $user->uid == $signup->uid;
    $can_edit = $admin || user_access('edit own signups') && $own;
    if (!$can_edit) {
      return;
    }
  }

  // We only need to do this for authenticated users signing up
  // themselves. We already collect the (presumably current) e-mail for
  // "anonymous" signups. If an administrator is signing up another user,
  // there's no reason to include the e-mail confirmation field, either.
