Controller（typesAction和typesAddAction）：

public function typesAction()
{       
    $em = $this->getDoctrine()->getManager();
    $types = $em->getRepository('CsmBundle:Type')->findAll();

    $newType = new Type();
    $form = $this->createFormBuilder($newType)
        ->add('typeName', 'text')
        ->add('description', 'text')
        ->add('starterPath', 'text')
        ->getForm();

    return $this->render('CsmBundle:Root:types.html.twig', array(
        'types' => $types,
        'form' => $form->createView()
    ));
}

public function typesAddAction(Request $request)
{
    $newType = new Type();

    $form = $this->createFormBuilder($newType)
        ->add('typeName', 'text')
        ->add('description', 'text')
        ->add('starterPath', 'text')
        ->getForm();

    if ($request->getMethod() == 'POST')
    {
        $form->bind($request);

        if ($form->isValid())
        {
            $em = $this->getDoctrine()->getManager();
            $em->persist($newType);
            $em->flush();

            return $this->redirect($this->generateUrl('root_types'));
        }
        else
        {
            $em = $this->getDoctrine()->getManager();
            $types = $em->getRepository('CsmBundle:Type')->findAll();

            return $this->render('CsmBundle:Root:types.html.twig', array(
                'types' => $types,
                'form' => $form->createView()
            ));
        }
    }
}

types.html.twig：

...
<form class="well" action="{{ path('root_types_add') }}" method="post" {{ form_enctype(form) }}>
<fieldset>
    <legend>Adding New Type</legend>
    <table border="0">

            <td width="100" align="left"><strong>Type name:</strong></td><td>{{ form_widget(form.typeName, { 'attr': {'class': 'txt'} }) }}</td>
        </tr>
        <tr>
            <td align="left"><strong>Description:</strong></td><td>{{ form_widget(form.description, { 'attr': {'class': 'txt'} }) }}</td>
        </tr>
        <tr>
            <td align="left"><strong>Starter:</strong></td><td>{{ form_widget(form.starterPath, { 'attr': {'class': 'txt'} }) }}</td>
        </tr>
        <tr>
            <td colspan="2">{{ form_errors(form) }}</td>
        </tr>
        <tr>
            <td colspan="2">{{ form_rest(form) }}</td>

        <tr>
            <td colspan="2" align="right"><button style="" class="btn btn-large btn-success" value="add" name="add">Add!</button></td>
        </tr>
    </table>
</fieldset>
</form>

问题：只有第一个字段（typeName）出错。如果我从HTML表单的所有字段输入不正确的数据，我只得到（！）第一个字段（typeName）的一个错误。如果我输入错误数据到第二个（描述）和第三个（starterPath）字段 - 我没有错误。

Answer 1

请在模板中使用{{ form_row(form.name) }}代替{{ form_widget(form.name)来解决问题....

form_widget仅呈现字段的html，而form_row呈现form_label，form_widget和form_errors的组合。

查看文档here。

如果您的表单冒充全局错误，请尝试在表单的默认选项中将error_bubbling设置为false（默认为true），如下所示：

$this->createFormBuilder($entity, array(
        'error_bubbling' => false,
        'data_class'     => 'Vendor\MyBundle\Entity\Name',
        // ... more options 
     )
 )
