Hub

Alternative storage and retrieval mechanism for custom forms.

How does it work?

The most common use-case is to use Hub in a custom form in your
administration UI. You can do this by return hub_closure(). The
hub_closure() function will handle populating default values, as
well as display the data structures in the form element's
#description for priviledged users.

function mymodule_general_settings($form, &$form_state) {
  $form['var1'] = array(
    '#type' => 'text',
    '#title' => t('Var 1'),
  );
  
  $form['var2'] = array(
    '#type' => 'date',
    '#title' => t('Var 2'),
  ),
  
  $form['set1'] = array(
    '#type' => 'fieldset',
    '#title' => t('Set 1'),
  );
  
  $form['set1']['var3'] = array(
    '#type' => 'checkboxes',
    '#title' => t('Var 3'),
    '#options' => array(
      'op1' => t('Option 1'),
      'op2' => t('Option 2'),
      'op3' => t('Option 3'),
    ),
  ),
  
  // .... etc.
  
  
  // hub_closure() arguments are a unique name for
  // your configuration object, and the form array.
  return hub_closure(__FUNCTION__, $form);
}

You could also create arbitrary Hub configurations with hub_save().

$config = new stdClass();
$config->name = 'mymodule_security_settings';
$config->data = array(
  'security_level' => array(
    'anonymous' => 'low',
    'authenticated' => 'medium',
    'administrator' => 'high',
  ),
);

hub_save('insert', $config);

Retrieve the data with hub_load().

$config = hub_load('mymodule_security_settings');

By the way, all your configurations are exportable.
