Expose node author's email address as a field

As long as the help text has a big warning in the field help text, i think this is acceptable. default drupal does not ever disclose user email address, thus the caution.

Here is a patch. this patch is running fine on boston2008 so i just set to RTBC

This worked for us also. (I added a handler function modeled on the author name handler function, but I'm sure the reason it didn't show up at first was not clearing the views cache at admin/build/views/tools .)

Some keywords to help people find this issue:

Node author's e-mail field for Drupal views
Drupal export users with e-mail addresses
Drupal show node author email Views
view user emails
show node author email

'help' should use double-quotes.

i've used this idea for comments emailaddresses but isn't there a way to put this in a seperate module. i don't want to modify the views module for this

Possible handler for creating a link to an individual users contact form:

/*
 * Format as a field as a user email to link to a contact form. Needs to also have a 'uid' available 
 */
function views_handler_field_usermail($fieldinfo, $fielddata, $value, $data) {
  if (module_exists('contact')) {
    return l($value, "user/". $data->users_uid ."/contact");
  }
  else {
    return $value;
  }
}

and in the original table definition change

      'mail' => array(
        'name' => t('User: Email'),
        'sortable' => TRUE,
        'help' => t('Display the user\'s email address. Beware that this should only be shown to administrators in a normal Drupal installation. Further, no attempt is made to obfuscate the email address.'),
      ),

to

      'mail' => array(
        'name' => t('User: Email'),
        'handler' => 'views_handler_field_usermail',
        'uid' => 'uid',
        'addlfields' => array('uid'),
        'sortable' => TRUE,
        'help' => t('Display the user\'s email address. No attempt is made to obfuscate the email address, so these should never be made public.'),
      ),

If the contact module is enabled, the email text links to the contact form, otherwise it displays as plain text. Since emails addresses of users are already always filtered, this doesn't need to be run through check_plain()

Applies correctly and works as expected.

Committed with slight corrections.
