你好对不起，但我的英语不好。

我正在 Symfony 2.3.6 中开发一个应用程序，我必须将用户的值保存在数据库（postgres）中。当我的具有 2 个提交按钮的嵌入表单（pais + 区域）用户按下第二个按钮时，就会出现问题。系统抛出

Child "salvar_region" does not exist.

问题是如果系统抛出异常，我如何检测是否按下了第二个按钮？

这是我的默认控制器

 public function addLocalAction(Request $request)
    {
        $region = new Region();
        $localidad = new Pais();
        $localidad->setRegion($region);
        $form = $this->createForm(new localidadType(), $localidad);  
         if($request->isMethod('POST')){
            $form->handleRequest($request);
            $form->getData();    




       if ($form->get('salvarPais')-> isClicked()){
        $objeto = new Pais();
        $objeto->setNombrePais($form->get('nombrePais')->getData());            
        $em = $this->getDoctrine()->getManager();
        $em->persist($objeto);
        $em->flush();}

       if ($form->get('salvarregion')->isClicked()){

        $objeto = new Region();
        $objeto->setNombreRegion($form->get('nombreRegion')->getData());
        $objeto->setNombreRegion($form->get('numeroRegion')->getData());
        $em = $this->getDoctrine()->getManager();
        $em->persist($objeto);
        $em->flush();}



        return $this->redirect($this->generateUrl('localidades'));


  }
    return $this->render('plataformaPlataformaBundle:Default:localidades.html.twig', array('form'=> $form->createView()));
}

我的 html.twig

<form action="{{ path('localidades')}}" method="post" {{ form_enctype(form) }}>
<h3>Agregar País</h3>
<div class="pais">
    {{ form_row(form.nombrePais) }}
    {{ form_row(form.salvarPais) }}
</div>   


<form action="{{ path('localidades')}}" method="post" {{ form_enctype(form) }}>
    <h3>Agregar Region</h3>

    <div class="region">
        {{ form_start(form) }}
            {{ form_errors(form)}}
            {{ form_row(form.region.nombreRegion) }}
            {{ form_row(form.region.numeroRegion) }}
            {{ form_row(form.region.pais) }}
            {{ form_row(form.region.salvarregion) }}
        {{ form_end(form) }}

    </div>    

</form>

和我的 2 种表格

    public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('nombreRegion', 'text', array('label' => 'Nombre de Región: '));
    $builder->add('numeroRegion', 'integer', array('label' => 'Número de Región: '));
    $builder->add('pais', 'entity', array('label' => 'País al que pertenece: ',
        'class' => 'plataformaPlataformaBundle:Pais',
        'property' => 'nombrePais'));
    $builder->add('salvarregion', 'submit', array('label' => 'Guardar Región'));
    $builder->getForm();

}


  public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('nombrePais', 'text');
    $builder->add('salvarPais', 'submit', array('label' => 'Guardar País'));
    $builder->add('region', new regionType());
    $builder->getForm();

}

PD：如果有人可以帮助我，非常感谢 PDx2：这是 URL 请求的示例：{"region":{"nombreRegion":"ewrew","numeroRegion":"4","pais":"3 ","salvarregion":""},"_token":"853d5460b076e01fdf4cef4c59c33e836ab64af3"}

你得到的错误看起来不像你在构建过程中给按钮的名字。

无论如何，要判断是否单击了特定提交，您可以使用：

if($form->get('salvarregion')->isClicked()) {

}
