function _authorize_filetransfer_connection_settings_set_defaults
Sets the default settings on a file transfer connection form recursively.
The default settings for the file transfer connection forms are saved in the database. The settings are stored as a nested array in the case of a settings form that has fieldsets or otherwise uses a nested structure. Therefore, to properly add defaults, we need to walk through all the children form elements and process those defaults recursively.
Parameters
$element: Reference to the Form API form element we're operating on.
$key: The key for our current form element, if any.
array $defaults: The default settings for the file transfer backend we're operating on.

Code
function _authorize_filetransfer_connection_settings_set_defaults(&$element, $key, array $defaults) {
// If we're operating on a form element which isn't a fieldset, and we have
// a default setting saved, stash it in #default_value.
if (!empty($key) && isset($defaults[$key]) && isset($element['#type']) && $element['#type'] != 'fieldset') {
$element['#default_value'] = $defaults[$key];
}
// Now, we walk through all the child elements, and recursively invoke
// ourself on each one. Since the $defaults settings array can be nested
// (because of #tree, any values inside fieldsets will be nested), if
// there's a subarray of settings for the form key we're currently
// processing, pass in that subarray to the recursive call. Otherwise, just
// pass on the whole $defaults array.
foreach (element_children($element) as $child_key) {
_authorize_filetransfer_connection_settings_set_defaults($element[$child_key], $child_key, isset($defaults[$key]) && is_array($defaults[$key]) ? $defaults[$key] : $defaults);
}
