Make the site's domain name available to a node template in Drupal

Submitted by Benjamin Melançon on August 29, 2011 - 5:21pm

Current approach:

<?php
/**
 * Implements template_preprocess_node().
 */
function issy_preprocess_node(&$vars) {
  $vars['domain'] = $_SERVER['SERVER_NAME'];
}
?>

This makes a $domain variable available in node.tpl.php and its derivatives like node--event.tpl.php.

Using 'SERVER_NAME' is preferred over the $_SERVER['HTTP_HOST'] variable which can be spoofed by the user.
