In this example, we create a bundle MyBundle
in the directory src/MyProject
$ php app/console generate:bundle --namespace=MyProject/MyBundle --format=yml
Add these two routes in the routing file of the bundle.
# src/MyProject/MyBundle/Resources/config/routing.yml
myform:
pattern: /myform
defaults: { _controller: MyProjectMyBundle:Default:form }
myformsuccess:
pattern: /myformsuccess
defaults: { _controller: MyProjectMyBundle:Default:success }
Note! You may create form which is not relate on Entity.
Look at Validation of the forms which are built manually.
<?php
// src/MyProject/MyBundle/Entity/Product.php
namespace MyProject\MyBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Product
{
/**
* @Assert\NotBlank()
*/
protected $name;
/**
* @Assert\NotBlank()
* @Assert\Length(min=20)
*/
protected $price;
...
}
<!-- src/MyProject/MyBundle/Resources/views/Default/index.html.twig -->
<!-- MyProjectMyBundle:Default:index.html.twig -->
<!-- Include prerequisite librairies and bundles -->
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript" src="{{ asset('bundles/bazingaexposetranslation/js/translator.min.js') }}"></script>
<script type="text/javascript" src="{{ url('bazinga_exposetranslation_js', { 'domain_name': 'validators' }) }}"></script>
<!-- Call JsFormValidationBundle -->
{{ JSFV(form) }}
<!-- Display the form -->
<form method="post" {{ form_enctype(form) }}>
{{ form_widget(form) }}
<input type="submit" />
</form>
<?php
// src/MyProject/MyBundle/Controller/Default.php
namespace MyProject\MyBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use MyProject\MyBundle\Entity\Product;
class DefaultController extends Controller
{
public function formAction()
{
$product = new Product();
$form = $this->createFormBuilder($product)
->add('name', 'text')
->add('price', 'money', array('currency' => 'USD'))
->getForm();
$request = $this->get('request');
if ($request->getMethod() == 'POST') {
$form->bindRequest($request);
if ($form->isValid()) {
return $this->redirect($this->generateUrl('myformsuccess'));
}
}
return $this->render('MyProjectMyBundle:Default:index.html.twig', array( 'form' => $form->createView() ));
}
public function successAction()
{
return new Response('Product posted');
}
}
Execute this command to clear the cache:
$ php app/console cache:clear
Go to your form page. ( ie : http://localhost/app_dev.php/myform )
- Click in and out of a field, validation messages appear.
- Put some text in the name field and the number 10 in the price field.
- Submit the form.
- A validation message for the price field appears. The submit action is prevented by the bundle when all fields are not correctly filled.
