In all web applications, user input is handled by HTML Forms. Symfony has the form component to make easy and fast form implementation and handling. Here is a basic form layout that you may use to implement your own forms:


Basic Form Creation:
Let's say you want to create a simple contact form with a name, email, and message field.

// src/Form/ContactFormType.php
namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ContactFormType extends AbstractType
    public function buildForm(FormBuilderInterface $builder, array $options)
            ->add('name', TextType::class, ['label' => 'Name'])
            ->add('email', EmailType::class, ['label' => 'Email'])
            ->add('message', TextareaType::class, ['label' => 'Message']);

    public function configureOptions(OptionsResolver $resolver)
            // Configure the data class to store the form data (optional)
            'data_class' => 'App\Entity\Contact', // Replace with your entity class if using one


Using the Form in a Controller:
Now, you can use this form in a controller to handle form submission and processing.

// src/Controller/ContactController.php
namespace App\Controller;

use App\Form\ContactFormType;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class ContactController extends AbstractController
     * @Route("/contact", name="contact")
    public function contactForm(Request $request): Response
        // Create a new instance of your data class to store the form data (optional)
        $contact = new \App\Entity\Contact(); // Replace with your entity class if using one

        // Create the form
        $form = $this->createForm(ContactFormType::class, $contact);

        // Handle form submission
        if ($form->isSubmitted() && $form->isValid()) {
            // Process the form data, e.g., sending an email or saving to the database

            // Redirect to a success page or display a success message
            return $this->redirectToRoute('success_page');

        return $this->render('contact/contact_form.html.twig', [
            'form' => $form->createView(),


Rendering the Form in a Twig Template:
Finally, render the form in a Twig template.

{# templates/contact/contact_form.html.twig #}
{% extends 'base.html.twig' %}

{% block content %}
    <h1>Contact Form</h1>
    {{ form_start(form) }}
    {{ form_row( }}
    {{ form_row( }}
    {{ form_row(form.message) }}
    <button type="submit">Submit</button>
    {{ form_end(form) }}
{% endblock %}


The Form Component provides many options and features to handle form rendering, validation, and data processing, making it a powerful tool for managing form data in Symfony applications.
