在Symfony 2.7中以字符串形式获取表单验证错误

Question

I'm getting a few form errors but i'm struggling to understand what the errors are, hence why the form is invalid. I'm using Symfony 2.7 and getting the errors using;

$errors = $form->getErrors(true, true);

I'd like them as a string so I can pass them to our logging application, however these are currently coming through as <empty>.

maybe try

$form->getErrorsAsString()

When having trouble to retrieve errors from a form (mostly when several forms are nested), I use these 2 custom utils functions :

public function getErrorMessagesFromUnbubblingForm(\Symfony\Component\Form\FormInterface $form)
{
    $errors = array();
    foreach ($form->getErrors() as $key => $error) {
        $template = $error->getMessageTemplate();
        $parameters = $error->getMessageParameters();

        foreach ($parameters as $var => $value) {
            $template = str_replace($var, $value, $template);
        }

        $errors[$key] = $template;
    }
    if ($form->count()) {
        foreach ($form as $child) {
            if (!$child->isValid()) {
                $errors[$child->getName()] = $this->getErrorMessagesFromUnbubblingForm($child);
            }
        }
    }
    return $errors;
}

public function getFlatErrorMessagesFromUnbubblingForm(\Symfony\Component\Form\FormInterface $form)
{
    $errors = array();
    foreach ($form->getErrors() as $error) {
        $template = $error->getMessageTemplate();
        $parameters = $error->getMessageParameters();

        foreach ($parameters as $var => $value) {
            $template = str_replace($var, $value, $template);
        }

        $errors[] = $template;
    }
    if ($form->count()) {
        foreach ($form as $child) {
            if (!$child->isValid()) {
                $errors = $this->getFlatErrorMessagesFromUnbubblingForm($child);
            }
        }
    }
    return $errors;
}
