Symfony

Step 1

Set the path to project folder in the command prompt

Step 2

Type the following command

            Php app/console server:run

Step 3

Create Entity folder in the demobundle à project/project1/src/Acme/DemoBundle

In the Entity folder, create new file à Person.php ( contains attributes, asserts, getter and setters )

Person.php

<?php

namespace Acme\DemoBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Person

{

 /**

  *@Assert\NotBlank()

  *@Assert\Email()

 */

 protected $email;

 /**

  *@Assert\NotBlank()

 */

 protected $fullname;

 public function getEmail()

 {

  return $this -> email;

 }

 public function setEmail($email)

 {

  $this-> email = $email;

 }

 public function getFullname()

 {

  return $this->fullname;

 }

 public function setFullname($fullname)

 {

  $this-> fullname = $fullname;

 }

}

?>

Step 4

Create php file in Acme/Demobundle/Form as PersonType.php.

In here we create the form to be appeared on the browser

PersonType.php

<?php

Namespace Acme\DemoBundle\Form;

use Symfony\Component\Form\AbstractType;

use Symfony\Component\Form\FormBuilderInterface;

class PersonType extends AbstractType

{

 Public function buildForm(FormBuilderInterface $builder, array $options)

 {

  $builder -> add('email','email')->add('fullname','text')->add('submit','submit');

 }

 Public function getName()

 {

  return 'person';

 }

}

Step 5

We modify the twig.

Demobundle à resources à views à welcome folder à index.html.twig

Remove all the <div> blocks and contents within them.

Index.html.twig

{% extends 'AcmeDemoBundle::layout.html.twig' %}

{% block title %}Symfony - Welcome{% endblock %}

{% block content_header '' %}

{% block content %}
    {% set version = constant('Symfony\\Component\\HttpKernel\\Kernel::MAJOR_VERSION') ~ '.' ~ constant('Symfony\\Component\\HttpKernel\\Kernel::MINOR_VERSION')%}

    <h1 class="title">Welcome!</h1>

    <p>Congratulations! You have successfully installed a new Symfony application.</p>
 
 {{form_start(form , {attr : {novalidate:'novalidate'}})}}
 {{form_row(form.email)}}
 {{form_row(form.fullname)}}
 {{form_end(form)}}
 
{% endblock %}

Step 6

We modify the WelcomeController

Demobundle à controller à WelcomeController

welcomController.php

<?php

namespace Acme\DemoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

use Acme\DemoBundle\Entity\Person;

use Acme\DemoBundle\Form\PersonType;

use Symfony\Component\HttpFoundation\Response;

class WelcomeController extends Controller

{

    public function indexAction()

    {

        /*

         * The action's view can be rendered using render() method

         * or @Template annotation as demonstrated in DemoController.

         *

         */

   

   //$user=array('name'=>'Nimal','active'=>true);

   

   $person = new Person();

   $form = $this->createForm(new PersonType(),$person);

   

   

  $request = $this->get('request');

  $form-> handleRequest($request);

  if($request->getMethod() == 'POST')

  {

   if($form -> isValid())

   {

    return new Response('Person Created');

   }

   else

   {

    return new Response('Error Occured while creating Person');

   }

   

  

   //return $this->render(‘AcmeDemoBundle:Main:index.html.twig’, array[‘form’=>$form=>createView()]);

   

  

  }

 

  return $this->render('AcmeDemoBundle:Welcome:index.html.twig' , array('form'=>$form->createView()));

 }

}
