empty fields not to be included in e-mail

In your custom e-mail template, you can add a few lines to remove components that do not have any value. You'll just need to expand on the example already provided in the .tpl.php file.

In your webform-mail.tpl.php that you've copied to your theme directory change lines 38 through 43 to:

  // Print out all the Webform fields. This is purposely a theme function call
  // so that you may remove items from the submitted tree if you so choose.
  // unset($form_values['submitted_tree']['element_key']);
  foreach ($form_values['submitted_tree'] as $key => $value) {
    if ($value == '') {
      unset($form_values['submitted_tree'][$key]);
    }
  }

  print theme('webform_mail_fields', 0, $form_values['submitted_tree'], $node);

Right... in which case you'll need to do multiple loops (or recursive looping) to remove all the empty values inside of fieldsets. The approach I used above would only work if you didn't use any fieldsets. Multiple pages do not make a difference though when dealing with e-mails.

Something like this should be pretty close. Again, not tested.

  // Print out all the Webform fields. This is purposely a theme function call
  // so that you may remove items from the submitted tree if you so choose.
  // unset($form_values['submitted_tree']['element_key']);
  if (!function_exists('webform_empty_fields')) {
    function webform_empty_fields(&$form_values) {
      foreach ($form_values as $key => $value) {
        if ($value == '') {
          unset($form_values[$key]);
        }
        if (is_array($value)) {
          webform_empty_fields($form_values[$key]); 
        }
      }
    }
  }

  webform_empty_fields($form_values['submitted_tree']);

  print theme('webform_mail_fields', 0, $form_values['submitted_tree'], $node);

Ha! I can't believe that worked ;)

What's happening is the empty array of values is still left, even though all the values are gone. This *should* remove the empty array too.

  // Print out all the Webform fields. This is purposely a theme function call
  // so that you may remove items from the submitted tree if you so choose.
  // unset($form_values['submitted_tree']['element_key']);
  if (!function_exists('webform_empty_fields')) {
    function webform_empty_fields(&$form_values) {
      foreach ($form_values as $key => $value) {
        if ($value == '') {
          unset($form_values[$key]);
        }
        if (is_array($value)) {
          webform_empty_fields($form_values[$key]);
          if (empty($form_values[$key])) {
            unset($form_values[$key]);
          }
        }
      }
    }
  }

  webform_empty_fields($form_values['submitted_tree']);

  print theme('webform_mail_fields', 0, $form_values['submitted_tree'], $node);

Hey there,
I am trying to accomplish this as well (empty fields to be excluded in the form email). After editing my drupal/modules/webforms/webform-mail.tpl.php I am still getting empty fields sent in my emails. Here is what I have done:

Edited the drupal/modules/webforms/webform-mail.tpl.php file to read:

<?php
// $Id: webform-mail.tpl.php,v 1.1.2.5 2009/11/06 00:59:47 quicksketch Exp $

/**
 * @file
 * Customize the e-mails sent by Webform after successful submission.
 *
 * This file may be renamed "webform-mail-[nid].tpl.php" to target a
 * specific webform e-mail on your site. Or you can leave it
 * "webform-mail.tpl.php" to affect all webform e-mails on your site.
 *
 * Available variables:
 * - $form_values: The values submitted by the user.
 * - $node: The node object for this webform.
 * - $user: The current user submitting the form.
 * - $ip_address: The IP address of the user submitting the form.
 * - $sid: The unique submission ID of this submission.
 * - $cid: The component for which this e-mail is being sent.
 *
 * The $cid can be used to send different e-mails to different users, such as
 * generating a reciept-type e-mail to send to the user that filled out the
 * form. Each form element in a webform is assigned a CID, by doing special
 * logic on CIDs you can customize various e-mails.
 */
?>
<?php print t('Submitted on @date', array('@date' => format_date(time(), 'small'))) ?>

<?php if ($user->uid): ?>
<?php print t('Submitted by user: @username [@ip_address]', array('@username' => $user->name, '@ip_address' => $ip_address)) ?>
<?php else: ?>
<?php print t('Submitted by anonymous user: [@ip_address]', array('@ip_address' => $ip_address)) ?>
<?php endif; ?>


<?php print t('Submitted values are') ?>:

<?php
  // Print out all the Webform fields. This is purposely a theme function call
  // so that you may remove items from the submitted tree if you so choose.
  // unset($form_values['submitted_tree']['element_key']);
  if (!function_exists('webform_empty_fields')) {
    function webform_empty_fields(&$form_values) {
      foreach ($form_values as $key => $value) {
        if ($value == '') {
          unset($form_values[$key]);
        }
        if (is_array($value)) {
          webform_empty_fields($form_values[$key]);
          if (empty($form_values[$key])) {
            unset($form_values[$key]);
          }
        }
      }
    }
  }

  webform_empty_fields($form_values['submitted_tree']);

  print theme('webform_mail_fields', 0, $form_values['submitted_tree'], $node);

?>

<?php print t('The results of this submission may be viewed at:') ?>

<?php print url('node/'. $node->nid .'/submission/'. $sid, array('absolute' => TRUE)) ?>

Let me know if I can provide any more information. Any help would be greatly appreviated. Thanks in advance!

Any idea?

Any help on how to do this in 6.x-3.0-beta 5?. Above methods won't work sadly enough.

Subscribing

Subscribing - I get the following error when using the previously mentioned code

warning: Invalid argument supplied for foreach() in modules/webform/templates/webform-mail.tpl.php on line 29.

Subscribing.
Just like in email, I also want to the webform displays only the non empty fields in the result (Submissions) page.
Thank you!

I also want to remove the empty fields from the e-mail? I have a very long form with many fieldsets.
All the solutions above won't work.
Is there a solution what works with the webform module 6.x-3.4.

Thank you

Subscribing

The solution above is for the 6.x-2.x branch.

The solution for the 6.x-3.x branch can be found here:
http://drupal.org/node/749360#comment-2751838

Can anyone suggest a working solution for Webform 6.x-3.20? Have tried the above solution in template.php:

<?php
function mytheme_webform_element_text($element, $value) {
  // Check if there is any value to print out at all, if not, return an empty string.
  if (strlen(trim($value)) == 0) {
    return '';
  }
  // Call the default theme function if there is a value.
  return theme_webform_element_text($element, $value);
}
?>

...which does not seem to work and comment #23 refers to what has become the 7.x version.

Thanks.

The 6.x branch is receiving critical bug fixes only.
