How to get form data in Symfony?

@adan 

In Symfony, you can get form data in a controller by using the getData() method on the form object. For example, if you have a form object called $form, you can get the form data by calling $form->getData().

Here is an example of how you might use this method in a controller action:

public function createAction(Request $request)
{
    // Create the form and handle the request
    $form = $this->createForm(MyFormType::class);
    $form->handleRequest($request);

    // Check if the form is valid and save the data
    if ($form->isValid()) {
        $data = $form->getData();
        // Save the data to the database, send an email, etc.
    }

    // Render the form template
    return $this->render('form.html.twig', array(
        'form' => $form->createView(),
    ));
}

In this example, the form data is accessed in the if block after the form has been submitted and validated. You can then use the $data variable to access the form data and use it as needed (e.g., to save it to the database).

Note that the form data is returned as an array or an object, depending on the data class specified in the form type. You can access individual fields in the form data by using array notation or object properties, respectively.

I hope this helps! Let me know if you have any questions.
