Question

我遇到了表单和POST方法的问题。我在控制器中创建一个表单，如下所示：

 $total =0;
function payableAmount($totalPrice){    
   // calculate total price here
   global $total;
    $total += $totalPrice;
    echo $total;
}

我以这种方式在路由文件中配置“ ricerca_index ”：

$form = $this->createFormBuilder()
        ->setAction($this->generateUrl('ricerca_index'))
        ->setMethod('POST')
        ->add('search', 'text',array(
                'label'=>'Cerca',
                'required'=>false))
        ->add('submit', 'submit', array('label' => 'Cerca'))
        ->getForm();       

    $name = $request->getLocale();
    return $this->render('DtEcBundle:Default:index.html.twig',array(
            'form' => $form->createView()

在我的目标页面的控制器中，我用这种方式编写了在ricerca_index中打印我的变量：

     ################################################################################
     #                               ricerca                                        #
     ################################################################################

ricerca_index:
      host:      "{_locale}.{domain}"
      locales:  { it: "/ricerca.{_format}", fr: "/ricerca.{_format}", de:    "/ricerca.{_format}" }
      defaults:  { _locale: "%locale%", domain: "%domain%", _format: "html",     _controller: DtEcBundle:Search:index }
requirements:
    _locale: "it|fr|de"
    domain:  "%domain%"
    _format:  "html|json"
    method:  "POST"

ricerca_index_www.it:
     path:      /ricerca.{_format}
     host:      "www.{domain}"
     defaults:  { _locale: "%locale%", _format: "html", _controller: DtEcBundle:Search:index }
requirements:
    _locale: "%locale%"
    domain:  "%domain%"
    _format:  "html|json"
    method:  "POST"

ricerca_index_nowww.it:
     path:      /ricerca.{_format}
     host:      "{domain}"
     defaults:  { _locale: "%locale%",  _format: "html", _controller:            DtEcBundle:Search:index }
requirements:
    _locale: "%locale%"
    domain:  "%domain%"
    _format:  "html|json"
    method:  "POST"

在twig文件中，我会打印我的变量形式“ textbox ”，然后我写下这段代码：

use Symfony\Component\HttpFoundation\Request;
class SearchController extends Controller {

public function indexAction(Request $request) {

    $search = $request->get('search');

    return $this->render('DtEcBundle:Search:index.html.twig',array(
            "search" => $search,

    ));

}

我没有收到错误，但我的转储变量为null，问题在哪里？我是Symfony的新手。我怎样才能在页面中打印我的变量？

就这样做：

$searchForm = $request->get('form');
$search = $searchForm['search'];

而不是$ request-＆gt; get（'search'）;

您的帖子数据实际上是这样的：

[
    'form' => [
        'search' => <search_val>,
        <...> // other values if any
    ]
]
