How to get form values in Symfony2 controller

Question

I am using a login form on Symfony2 with the following controller code

public function loginAction(Request $request)
{
    $user = new SiteUser();
    $form          


        

Answer 1

Simply :

$data = $form->getData();

Answer 2

To get the data of a specific field,

$form->get('fieldName')->getData();

Or for all the form data

$form->getData();

Link to docs: https://symfony.com/doc/2.7/forms.html

Answer 3

If you're using Symfony 2 security management, you don't need to get posted values, you only need to manage form template (see documentation).

If you aren't using Symfony 2 security management, I advise you strongly to use it. If you don't want to or if you can't, can you give us the LoginType's sources ?

Answer 4

If you have extra fields in the form that not defined in Entity , $form->getData() doesn't work , one way could be this :

$request->get("form")["foo"] 

Or :

$form->get('foo')->getData();

Answer 5

For not mapped form fields I use $form->get('inputName')->getViewData();

Answer 6

None of the above worked for me. This works for me:

$username = $form["username"]->getData();
$password = $form["password"]->getData();

I hope it helps.
