User Account Via Submit Field

I apologize, I should have explained a little more.

The email I need to display is that of the article author from their user account. I imagine I can get it using SQL, but I'm wondering if there is a simpler way.

Thank you

Update in case anyone needs it in the future. I added the following to a module and displayed it in a Flexi field

<?php
// no direct access
defined('_JEXEC') or die('Go Away');

//Grab the user ID of the author from the content component
$cdd_article =& JTable::getInstance('content');
$cdd_article->load(JRequest::getInt('id'));
$cdd_authorid = $cdd_article->created_by;

//Grab the contact associated with the above user ID
$db =& JFactory::getDBO(); //Establish DB Link
$query = "SELECT * FROM #__users WHERE id = " . $cdd_authorid ;
$db->setQuery($query); //Execute query. Should return 1 row
$cdd_contact = $db->loadAssoc(); //Load results as associative array


$cdd_email = $cdd_contact;

echo $cdd_email;

?>

in you template you can use some php code

$user = JFactory::getUser($item->created_by);
$email = $user->get('email');//user email
echo $email;

its done

I figured there had to be an easier way. As always, thank you for your help!

with pleasure
