How do I theme a fieldset's contents?

Posted by RodrigoBalest on February 27, 2013 at 9:19pm

Hi.

I'm trying to theme a fieldset generated by the module Field Group (http://drupal.org/project/field_group).

I'm implementing the following hook_fieldset in my theme:

function MYTHEME_fieldset($variables) {
	$element = $variables['element'];
	element_set_attributes($element, array('id'));
	_form_set_class($element, array('form-wrapper'));

	$output = '<fieldset' . drupal_attributes($element['#attributes']) . '>';
	if (!empty($element['#title'])) {
	  // Always wrap fieldset legends in a SPAN for CSS positioning.
	  $output .= '<legend><span class="fieldset-legend">' . $element['#title'] . '</span></legend>';
	}
	$output .= '<div class="fieldset-wrapper">';
	if (!empty($element['#description'])) {
	  $output .= '<div class="fieldset-description">' . $element['#description'] . '</div>';
	}
	if(function_exists('render_' . $element['#id']))
	{
		var_dump('render_' . $element['#id']);
		$output .= call_user_func('render_' . $element['#id'], array($element));
	}
	else
	{
		$output .= $element['#children'];
	}
	if (isset($element['#value'])) {
	  $output .= $element['#value'];
	}
	$output .= '</div>';
	$output .= "</fieldset>\n";
	return $output;
}

And the function that (tries to) render de fieldset contents:

function render_node_vehicle_form_group_precos_radio($element)
{
	//var_dump($element[0]['field_radio_deftime_15']);
	$table = '<table>';
	$table .= '<thead><tr><td></td><th scope="col">15&Prime;</th><th scope="col">30&Prime;</th></tr><thead>';
	$table .= '<tbody>';
	$table .= '<tr><th scope="row">Defined time</th><td>' . drupal_render($element[0]['field_radio_deftime_15']) . '</td><td>' . drupal_render($element[0]['field_radio_deftime_30']) . '</td></tr>';
	$table .= '<tr><th scope="row">Undefined time</th><td>' . drupal_render($element[0]['field_radio_undeftime_15']) . '</td><td>' . drupal_render($element[0]['field_radio_undeftime_30']) . '</td></tr>';
	$table .= '</tbody>';
	$table .= '</table>';
	return $table;
}

As you can see, I tryed var_dump the field, and found out that it's ['#printed'] key is 'true', and it makes drupal_render returns nothing.

So, what's the right way of achieve this?

Thanks!

Solved. That's what I did:

In the example above, just changed (eg.)

drupal_render($element[0]['field_radio_undeftime_15'])

with

$element[0]['field_radio_undeftime_15']['#children']

Thanks.
