To finish this example, let's add our theme function to produce the proper output.
if (!empty($list)) {
// Prepare the information for theming.
$variables = array(
'items' => $list,
);
$content = theme('item_list', $variables);
// Attach the content to the user page according to the API.
if (!isset($account->content['example'])) {
$account->content['example'] = array();
}
$account->content['example'] += array(
'#type' => 'user_profile_category',
'#attributes' => array('class' => array('user-member')),
'#weight' => 5,
'#title' => t('Content'),
);
$account->content['example']['output'] = array(
'#type' => 'user_profile_item',
'#title' => t('Content creation permissions'),
'#markup' => $content,
'#attributes' => array('class' => array('content-creation')),
);
}
}
With this theme function in place, we can display the following output:
