namespace Sym\FormBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sym\FormBundle\Entity\TblCust;
use Symfony\Component\HttpFoundation\Request;
use Sym\FormBundle\Form\TblCustType;
class DefaultController extends Controller
{
public function indexAction(Request $request)
{
$tbl = new TblCust();
// $form = $this->createForm(new TblCustType(),$tbl);
$form = $this->createFormBuilder($tbl)
->add('custName','text')
->add('custCity','text')
->add('custAddress','text')
->add('custPhno','text')
->add('save','submit')

$form->handleRequest($request);
if($form->isValid()){
$em = $this->getDoctrine()->getManager();
$em = persist('$tbl');
$em->flush();
return new response('New Customer Added..!');
}

index.html.twig
{% block gender_widget %}
{% spaceless %}
{% if form %}
<ul {{ block('widget_container_attributes') }}>
{% for child in form %}
<li>
{{ form_widget(child) }}
{{ form_label(child) }}
</li>
{% endfor %}
</ul>
{% else %}
{# just let the choice widget render the select tag #}
{{ block('choice_widget') }}
{% endif %}
{% endspaceless %}
{% endblock %}
{% block container %}
{% endblock%}
I have created form using doctrine:generate:bundle symfony commend
TblCustType.php
<?php
namespace Sym\FormBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class TblCustType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('custName')
->add('custCity')
->add('custAddress')
->add('custPhno')
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Sym\FormBundle\Entity\TblCust'
));
}
/**
* #return string
*/
public function getName()
{
return 'sym_formbundle_tblcust';
}
}
My output is looking like below image
My problem is when i click on submit button it doesn't return response and i can not save my record. Please help my out this.

Answer 1

I believe you need to put the form tag in twig:
{{ form_start(form) }}
//all form widgets
//submit button
{{ form_rest(edit_form) }} <-- so it renders the hidden ones like the csrf token
</form>

Answer 2

You need to use form_start, form_rest and form_end like that :
{% block gender_widget %}
{% spaceless %}
{% if form %}
{{ form_start(form) }}
<ul {{ block('widget_container_attributes') }}>
{% for child in form %}
<li>
{{ form_widget(child) }}
{{ form_label(child) }}
</li>
{% endfor %}
</ul>
{{ form_rest(form) }}
{{ form_end(form) }}
{% else %}
{# just let the choice widget render the select tag #}
{{ block('choice_widget') }}
{% endif %}
{% endspaceless %}
{% endblock %}
