Спасибо!

Korpch's function seems to be broken. Did not work as expected for me.

yapro's version worked, but was missing translation. Also it generated an array of arrays, which is not what i expected to get. I was looking for a way to get a simple plain list of error messages to display them to the user.

My final version:

     /**
     * @param \Symfony\Component\Form\Form $form
     * @return string[]
     */
    public static function getFormErrors(\Symfony\Component\Form\Form $form)
    {
        $errors = array();

        if ($form instanceof \Symfony\Component\Form\Form) {
            // find errors of this element
            foreach ($form->getErrors() as $error) {
                $errors[] = self::$translator->trans($error->getMessage(), array(), 'validators');
            }

            // iterate over errors of all children
            foreach ($form->all() as $key => $child) {
                if($child instanceof \Symfony\Component\Form\Form) {
                    /** @var $child \Symfony\Component\Form\Form */
                    $err = self::getFormErrors($child);
                    if (count($err) > 0) {
                        $errors = array_merge($errors, $err);
                    }
                }
            }
        }

        return $errors;
    }
