Create a simple form

symfony

Solution

The error has nothing to do with symfony, actually. It occurs because declaration of `buildForm` function does not match with that of base class (AbstractType). The first parameter of `buildForm` must be an instance of `FormBuilderInterface` whereas your first parameter is instance of `FormBuilder`

// ...
use Symfony\Component\Form\FormBuilderInterface;

class ContactForm extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    // ...

Problem

Just want to create a simple contact form in Symfony 2.1. How? ContactForm.php: ``` namespace frontend\mainBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilder; class ContactForm extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { $builder->add('subject', 'textarea'); $builder->add('email', 'email'); $builder->add('message', 'textarea'); } public function getName() { return 'contact'; } } ``` DefaultController.php ``` namespace frontend\mainBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use mylib\DataFormatChecker; use frontend\mainBundle\Form\ContactForm; use Symfony\Component\HttpFoundation\Request; class DefaultController extends Controller { public function contactAction(Request $request) { $task = array(); $form = $this->createFormBuilder(new ContactForm(), $task); if ($request->getMethod() == 'POST') { $form->bindRequest($request); if ($form->isValid()) { // perform some action, such as saving the task to the database //return $this->redirect($this->generateUrl('task_success')); } } return $this->render('frontendmainBundle:Default:contact.html.php', array( 'form' => $form->createView() )); } } ``` Error: Declaration of frontend\mainBundle\Form\ContactForm::buildForm() must be compatible with Symfony\Component\Form\FormTypeInterface::buildForm(Symfony\Component\Form\FormBuilderInterface $builder, array $options) in line 8 in ContactForm.php. What is wrong? Sorry, used to symfony 1.4
