domain_form_alter($form_id, &$form)
domain.module, line 982
Description
Implements hook_form_alter()
This function is crucial, as it appends our node access elements to the node edit form. For users without the "set domain access" permission, this happens silently.
Code
function domain_form_alter($form_id, &$form) {
// There are forms that we never want to alter, and they are passed here.
$forms = module_invoke_all('domainignore');
if (in_array($form_id, $forms)) {
return;
}
// Set a message if we are on an admin page.

// to the currently active domain. See http://drupal.org/node/196217.
