表单没有发送，我的代码有错误？

Question

I have a problem with the form, apparently not sent properly or there is some error. I'm new to Symfony and use version 3.0.

Sorry for my bad English.

Here is my code:

UserController.php

public function addAction()
{
    $user = new User();
    $form = $this->createForm(UserType::class, $user);

    return $this->render("asignacionesBundle:User:add.html.twig", array(
        'form' => $form->createView()
    ));
}

public function createAction(Request $request)
{
    $user = new User();
    $form = $this->createForm(UserType::class, $user);
    $form->handleRequest($request); #Obtengo el formulario y lo proceso.

    if($form->isSubmitted()) { #Compruebo si el formulario es válido
        $data = $this->getDoctrine->getManager(); # Busca el objeto en la entidad para procesar en la db
        $data->persist($user); # Administra el objeto
        $data->push(); # Procesa los datos, hace la insercción a la base de datos.

        return $this->redirectToRoute('asignaciones_index');
    } else {
        return $this->Response("Entro acá");
    }


    return $this->render("asignacionesBundle:User:add.html.twig", array(
        'form' => $form->createView()
    ));

}

Sorry for the mess of code, I hope you can help me. And sends the URL by pressing the button Submit:

web/app_dev.php/user/add?user%5Busername%5D=asdsadas&user%5BfirstName%5D=dasdasdsad&user%5BlastName%5D=asdsad&user%5Bemail%5D=asd%40email.com&user%5Bpassword%5D=asdsadasd&user%5Bisactive%5D=1&user%5Brole%5D=Administrador&user%5Bsave%5D=&user%5B_token%5D=0k9C38QskgnlnR-y-WodFaN4GQJOBBhdSk8r7_JUvzA

Answer 1

Your form action need to point to the route of the controller method createAction instead of addAction.

So try change the line:

        {{ form_start(form, {'action':'', 'method':'POST'}) }}

with something like:

        {{ form_start(form, {'action': path('_route_name') , 'method':'POST'}) }}

Where _route_name is the route name of the action method addAction. Here some example from the doc.

In addiction, in the addAction method i don't know what is the method push on the entity manager, i suspect a typo with the flush method for persisting the new object. So I think you need to change the following line:

    $data->push(); # Procesa los datos, hace la insercción a la base de datos.

with

    $data->flush(); 

Hope this help
