我的管理类

     public function getTemplate($name)
     {
       switch ($name) {
        case 'edit':
            if ($this->getSubject()->getId()) {
                return 'HelloAdminBundle:Builder:base_edit.html.twig';
            } else {
                return 'HelloAdminBundle:Builder:base_edit.html.twig';
            }
            break;
        default:
            return parent::getTemplate($name);
            break;
    }

}

protected function configureRoutes(RouteCollection $collection) {
$collection
    ->add('getArticleFromSection', 'getArticleFromSection')
    ;
}
protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper

        ->add('section')
        ->add('title','choice',array('required' => false ))

    ;
}

我的生成器:base_edit.html.twig

My Builder:base_edit.html.twig

     <script type="text/javascript">
     $(document).ready(function()
       {
         $("#{{ admin.uniqId }}_section").change(function()
        {
        var id=$(this).val();
        var dataString = 'id='+ id;
        $.ajax
        ({
            type: "POST",
            url: "{{ admin.generateObjectUrl('getArticleFromSection', object) }}",
            data: dataString,
            cache: false,
            success: function(html)
            {
                $("#{{ admin.uniqId }}_title").html(html);
            } 
        });
       });

     });

</script>

Ajax 请求控制器

    $article        = $this->get('hello_frontend.article');
    $totalArticle        = $article->getArticleByContentType($id);

     $html = "";
    foreach($totalArticle as $res){
    $html .="<option value=".$res->getId().">".$res->getTitle()."</option>";
    }

直到现在一切正常....

I am not able to figure out the problem. your help will be appreciated

推荐答案

Noscope，正是他想做的.他想动态填充第二个选择，所以他无法在管理类中填充它.

Noscope, it is exactly what he wants to do. He wants to populate the second select dynamically, so there is no way he could populate it in the admin class.

我遇到了同样的问题，我找不到如何解决它.我现在找到的唯一方法是检查 $this->container->get('request')->request->get('YourFormName[your_field]', null, true) 在我的行动中.

I have the same problem and I can't find how to solve it. The only way I've found for now is to check $this->container->get('request')->request->get('YourFormName[your_field]', null, true) in my action.
