A form theming example would be a nice addition to the form_example if you'd be interested in posting a patch. Thanks, -Randy On Sun, Oct 24, 2010 at 10:45 AM, Bob Hutchinson <hutchlists@midwales.com>wrote:

In D7 I get somewhat different behaviour:
If I do not create an entry in the theme registry, all works as expected, but if I do, things start to behave oddly.
function mymodule_theme() { ....
'mymodule_thingy_form' => array(
'variables' => array(
'form' => NULL,
),
),
In D7 the above should actually be:
'mymodule_thingy_form' => array( 'render element' => 'form',
.... } and create a function function theme_mymodule_thingy_form($variables) {
$form = $variables['form']; $output = drupal_render($form); return $output;
}
You should use either render() or drupal_render_children() rather than drupal_render(). So far as I could figure out, drupal_render() should no longer be used inside theme functions. You use render() to render a specific element, and drupal_render_children() to render all the children but NOT the element (which is what you want when attempting to render $form since that is currently being rendered).
I ran some trials using form_example from http://drupal.org/project/examples I found that indeed I should not use drupal_render() inside theme functions, drupal_render_children() works fine. I also found that using drupal_get_form() within a function (as opposed to in a menu) requires the output of drupal_get_form() to be run through render(), otherwise the form is not complete. The theme (defined with 'render element') is picked up automatically, the same as it is when calling drupal_get_form() directly in a menu $item.
Thanks for your help.
