我有一个与方法POST
一起使用的搜索表单,但方法POST
不会在网址中显示请求的数据。
使用方法POST
,网址如下所示:
/search_flight
方法GET
未找到任何结果,网址如下所示:
/search_flight?from=Cape+Town%2C+International+CPT&to=Johannesburg%2C+O.R.+Tambo+International+JNB&departuredate=2016%2F01%2F08&arrivaldate=2016%2F10%2F04&price=57.5%2C1000
我还注意到,使用方法GET
,数据会在表单的每个输入中重置。
的routing.yml
searchFlight:
path: /search_flight
defaults: { _controller: FLYBookingsBundle:Post:searchtabflightResult }
requirements:
_method: GET|POST
控制器
此方法将请求的数据发送到将处理查询的方法searchtabflightResultAction
。
public function searchtabflightAction()
{
//$form = $this->createForm(new SearchflightType(),null, array('action' => $this->generateUrl('searchFlight'),'method' => 'GET',));
$form = $this->get('form.factory')->createNamed(null, new SearchflightType());
return $this->render('FLYBookingsBundle:Post:searchtabflight.html.twig', array(
'form' => $form->createView(),
));
}
<form action="{{ path ('searchFlight') }}" method="GET">
{# here I have my forms #}
</form>
public function searchtabflightResultAction(Request $request)
{
//$form = $this->createForm(new SearchflightType());
$form = $this->get('form.factory')->createNamed(null, new SearchflightType());
$form->handleRequest($request);
$em = $this->getDoctrine()->getManager();
$airport1 = $form["to"]->getData();
$airport = $form["from"]->getData();
$departureDateObj = $form["departuredate"]->getData();
$arrivalDateObj = $form["arrivaldate"]->getData();
$price = $form["price"]->getData();
$entities = $em->getRepository('FLYBookingsBundle:Post')->searchflight($airport1,$airport,$departureDateObj,$arrivalDateObj,$price);
return $this->render('FLYBookingsBundle:Post:searchtabflightResult.html.twig', array(
'entities' => $entities,
'form' => $form->createView(),
));
}
如何使我的搜索过滤器与方法get?
一起使用答案 0 :(得分:1)
一切都应该在两个行动中完成,基本概念是:
SearchFlightType具有/ wo价格选项:
class SearchFlightType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('from', FormType\TextType::class)
->add('to', FormType\TextType::class)
->add('departuredate', FormType\TextType::class)
->add('arrivaldate', FormType\TextType::class);
if ($options['price']) {
$builder->add( 'price', FormType\TextType::class );
}
$builder
->add('submit', FormType\SubmitType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'price' => false,
));
}
}
Controller.php这样
class PostController extends Controller
{
/**
* @Route("/index", name="index")
*/
public function indexAction(Request $request)
{
$defaultData = array();
$form = $this->createForm(SearchFlightType::class, $defaultData, array(
// action is set to the specific route, so the form will
// redirect it's submission there
'action' => $this->generateUrl('search_flight_result'),
// method is set to desired GET, so the data will be send
//via URL params
'method' => 'GET',
));
return $this->render('Post/searchtabflight.html.twig', array(
'form' => $form->createView(),
));
}
/**
* @Route("/search_flight_result", name="search_flight_result")
*/
public function searchTabFlightResultAction(Request $request)
{
$defaultData = array();
$entities = null;
$form = $this->createForm(SearchFlightType::class, $defaultData, array(
// again GET method for data via URL params
'method' => 'GET',
// option for price form field present
'price' => true,
));
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// get data from form
$data = $form->getData();
// process the data and get result
$em = $this->getDoctrine()->getManager();
$entities = $em->getRepository('FLYBookingsBundle:Post')->searchflight($data['from'], $data['to'], ...);
}
return $this->render('Post/searchtabflight.html.twig', array(
'form' => $form->createView(),
// present the result
'entities' => $entites,
));
}
}
