To get user input with Twig and Symfony, you can follow the below steps:

  1. Create a new form in Symfony using the form builder or using an existing form class.
  2. In your controller, create a new instance of the form and pass it to the Twig template as a variable.
  3. In your Twig template, render the form fields using the form(form) function provided by Symfony.
  4. Add an action attribute to the form tag with the desired route to submit the form.
  5. Create a new controller action to handle the form submission. This action should accept a Request parameter.
  6. In the controller action, use the handleRequest() method of the form object to process the submitted data.
  7. If the form is valid, you can retrieve the user input using the getData() method of the form object.
  8. You can then handle the user input accordingly, such as saving it to a database or performing any necessary operations.


Here is an example:


In your controller:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
use AppFormExampleFormType;

public function exampleAction(Request $request)
{
    $form = $this->createForm(ExampleFormType::class);

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
        $data = $form->getData();
        // Handle the user input here
    }

    return $this->render('example.html.twig', [
        'form' => $form->createView(),
    ]);
}


In your Twig template (example.html.twig):

1
2
3
4
{{ form_start(form) }}
    {{ form_widget(form) }}
    <button type="submit">Submit</button>
{{ form_end(form) }}


Note: Replace ExampleFormType with the actual form class you want to use, and update the form fields and actions according to your requirements.
