It seems like getElements() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        if (is_array($elements)) {
            foreach ($elements as $name => $element) {

                    if (isset($request[$name])) {
                        $data = is_array($request[$name]) ? $request[$name] : [$request[$name]];
                        $element->getData($data, 'request');
                    }
                } else {
                    $value = isset($request[$name]) ? $request[$name] : null;
                    if (strpos($name, '[') && strpos($name, ']')) {
                        $arrayPrimary = substr($name, 0, strpos($name, '['));
                        $arrayKeys = str_replace($arrayPrimary, '', $name);

                        preg_match_all('/\[([^\]]*)\]/', $arrayKeys, $arr_matches, PREG_PATTERN_ORDER);
                        $value = $request[$arrayPrimary];
