3. 11.x core/lib/Drupal/Core/FileTransfer/Form/FileTransferAuthorizeForm.php \Drupal\Core\FileTransfer\Form\FileTransferAuthorizeForm::setConnectionSettingsDefaults()

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 details 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.

Provides the file transfer authorization form.

Namespace

Code

protected function setConnectionSettingsDefaults(&$element, $key, array $defaults) {
    // If we're operating on a form element which isn't a details, and we have
    // a default setting saved, stash it in #default_value.
    if (!empty($key) && isset($defaults[$key]) && isset($element['#type']) && $element['#type'] != 'details') {
        $element['#default_value'] = $defaults[$key];
    }
    // Now, we walk through all the child elements, and recursively invoke
    // ourselves on each one. Since the $defaults settings array can be nested
    // (because of #tree, any values inside details 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) {
        $this->setConnectionSettingsDefaults($element[$child_key], $child_key, isset($defaults[$key]) && is_array($defaults[$key]) ? $defaults[$key] : $defaults);
    }
}
